DETAILED DESCRIPTION

[0018] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0019] Before further describing the embodiments of the present disclosure in detail, the nouns and terms involved in the embodiments of the present disclosure are first described. The nouns and terms involved in the embodiments of the present disclosure are subject to the following interpretations: Mesoscale eddy: Mesoscale eddy is a common vortex phenomenon in the ocean. Its spatial scale is generally between tens of kilometers and hundreds of kilometers, and its life cycle ranges from a few days to a few months. Mesoscale eddy has obvious rotation characteristics and is divided into cyclonic eddy (CE) and anticyclonic eddy (AE). In the method disclosed in the present invention, CE and AE need to be processed separately.

[0020] The flow field corresponding to the mesoscale eddy: refers to the flow state of seawater in the ocean area where the mesoscale eddy exists. The flow field can be described by velocity, including the magnitude and direction of the flow velocity. The flow field structure of the mesoscale eddy is complex, and the flow velocity and direction are usually different in the center and edge of the vortex.

[0021] Marine heatwave: Marine heatwave refers to a phenomenon in which the ocean surface temperature is significantly higher than the historical average temperature for a certain period of time. Marine heatwaves can have serious impacts on marine ecosystems and climate.

[0022] In a first aspect of the present disclosure, a method for determining the correspondence between a mesoscale eddy and an ocean heat wave is provided, such as Figure 1 As shown, the method includes: Step 101, for each mesoscale eddy, determine the target flow field data and target ocean heat wave data corresponding to the mesoscale eddy; the target flow field data includes the initial flow field rectangular coordinates and the corresponding flow field velocity, and the target ocean heat wave data includes the initial ocean heat wave rectangular coordinates and the corresponding ocean heat wave intensity.

[0023] First, for each mesoscale eddy, the data within the range of the mesoscale eddy are screened out from a large amount of flow field data and ocean heat wave data, and these data are used as target flow field data and target ocean heat wave data, respectively. Among them, the target flow field data includes the initial flow field rectangular coordinates of multiple flow field points, and the initial flow field rectangular coordinates are the specific positions of the flow field points in the Cartesian coordinate system. And the flow field velocity of each flow field point at this position. The flow field velocity is the speed and direction of the flow of seawater at this point. The target ocean heat wave data includes the initial ocean heat wave rectangular coordinates of each ocean heat wave, and the initial ocean heat wave rectangular coordinates are the specific positions of the ocean heat wave in the Cartesian coordinate system. And the corresponding ocean heat wave intensity at each position. The intensity of the ocean heat wave is the degree of abnormal increase in ocean temperature.

[0024] Step 102, converting the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates to obtain the initial flow field polar coordinates and the initial ocean heat wave polar coordinates.

[0025] The initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are expressed based on the Cartesian coordinate system. In order to more accurately describe the spatial correspondence between the mesoscale eddy and the ocean heat wave, this step converts the rectangular coordinates. Specifically, the center of the mesoscale eddy is used as the origin of the polar coordinates. Using a coordinate conversion algorithm or formula, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are converted into initial flow field polar coordinates and initial ocean heat wave polar coordinates, respectively.

[0026] Step 103, based on the initial flow field polar coordinates and the initial ocean heat wave polar coordinates, obtain the target flow field polar coordinates and the target ocean heat wave polar coordinates within a plurality of preset angle intervals corresponding to the mesoscale vortex.

[0027] For flow field data, the initial flow field polar coordinates often present a non-uniform distribution in space. This non-uniform distribution will bring certain difficulties to subsequent analysis. By classifying each data point into the corresponding preset angle interval, the target flow field polar coordinates are obtained, and the flow field data can be standardized in azimuth, so that the data in each preset angle interval has relatively consistent azimuth characteristics. Similarly, the initial ocean heat wave polar coordinates also have uneven azimuth distribution. Using the same processing method as the flow field data, the initial ocean heat wave polar coordinates are divided according to the preset angle interval to obtain the target ocean heat wave polar coordinates.

[0028] The division criteria of the preset angle interval can be determined according to actual needs. Smaller angle intervals can provide more detailed azimuth information, but may result in insufficient data in some intervals. Larger angle intervals can ensure data volume, but may lose azimuth resolution. Therefore, the specific value of the preset angle interval can be determined based on factors such as data distribution characteristics and research purpose.

[0029] Step 104, obtaining the correspondence between the mesoscale eddies and the ocean heat waves according to the target flow field polar coordinates and the corresponding flow field velocities, the target ocean heat wave polar coordinates and the corresponding ocean heat wave intensities corresponding to the multiple mesoscale eddies.

[0030] The target flow field polar coordinates reflect the position of each flow field point relative to the center of the mesoscale eddy through the polar diameter and polar angle, and the flow field velocity reflects the speed and direction of the seawater flow at that location. Together, they describe the characteristics of the mesoscale eddy field. The target ocean heat wave polar coordinates reflect the position of the ocean heat wave relative to the center of the mesoscale eddy through the polar diameter and polar angle, and the ocean heat wave intensity reflects the degree of abnormal increase in ocean temperature at that location. Together, they describe the characteristics of the ocean heat wave.

[0031] By comprehensively considering the target flow field polar coordinates and their corresponding flow field velocities, the target ocean heat wave polar coordinates and their corresponding ocean heat wave intensities corresponding to multiple mesoscale eddies, more comprehensive information can be obtained to determine the corresponding relationship between mesoscale eddies and ocean heat waves.

[0032] First, based on the combined target flow field polar coordinates and target ocean heat wave polar coordinates, the relationship between mesoscale eddies and ocean heat waves can be determined from the perspective of spatial position. For example, at a location determined by a specific polar diameter and polar angle, if the flow field exhibits a strong rotation feature and the intensity of the ocean heat wave at that location is also at a high level, then this indicates that the two are closely related in spatial position.

[0033] Secondly, based on the combined flow velocity and ocean heat wave intensity, the relationship between mesoscale eddies and ocean heat waves can be determined from the perspective of intensity. For example, when the flow velocity is faster, the intensity of ocean heat waves will increase or decrease accordingly.

[0034] In order to more clearly and intuitively show the spatial relationship between the mesoscale eddy and the ocean heat wave, the combined target flow field polar coordinates and the target ocean heat wave polar coordinates can also be converted into rectangular coordinates before analysis. This method will be elaborated in detail in the subsequent embodiments and will not be repeated here.

[0035] The method for determining the correspondence between mesoscale eddies and ocean heat waves in this embodiment is to convert the flow field data and ocean heat wave data corresponding to the mesoscale eddies in the rectangular coordinate system into the polar coordinate system. Then, in the polar coordinate system, the flow field data and ocean heat wave data are unified into a preset angle range. In this way, the flow field data and ocean heat wave data corresponding to all mesoscale eddies can be synthesized. Based on the synthesized data, the correspondence between the mesoscale eddies and the ocean heat waves is determined. The influence of the spatial asymmetry of the mesoscale eddies on the calculation of the spatial correspondence between the mesoscale eddies and the ocean heat waves is overcome. In this way, a more accurate correspondence between the mesoscale eddies and the ocean heat waves can be obtained, which provides technical support for evaluating the influence of the mesoscale eddies on the ocean heat waves.

[0036] In one embodiment of the present disclosure, for each mesoscale eddy, target flow field data and target ocean heat wave data corresponding to the mesoscale eddy are determined, which can be specifically achieved through the following steps: for each mesoscale eddy, based on the occurrence time and location of the mesoscale eddy, the original flow field data and the original ocean heat wave data are screened to obtain the target flow field data and the target ocean heat wave data.

[0037] The original flow field data refers to the collection of flow field data covering the entire research sea area and at different time points. Similarly, the original ocean heat wave data refers to the collection of ocean heat wave data covering the entire research sea area and at different time points. First, based on the occurrence time of the mesoscale eddy, the flow field data and ocean heat wave data that match the occurrence time of the mesoscale eddy are screened out from the original flow field data and original ocean data, respectively.

[0038] Based on the location where the mesoscale eddy occurs, the flow field data and ocean heat wave data within the range of the mesoscale eddy are screened out. Specifically, the longitude and latitude of the outermost envelope of the mesoscale eddy can be obtained. The mesoscale eddy is not a precise circle or regular shape, and the longitude and latitude of its outermost envelope can more accurately define the spatial range of the mesoscale eddy in the ocean. By comparing the geographic coordinate information in the original flow field data and the original ocean heat wave data, the flow field data and ocean heat wave data within the longitude and latitude of the outermost envelope are determined as the target flow field data and target ocean heat wave data.

[0039] In one embodiment of the present disclosure, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are converted to obtain the initial flow field polar coordinates and the initial ocean heat wave polar coordinates, which can be specifically achieved by the following technical means: first, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are normalized to obtain the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates; then, the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates are converted to obtain the initial flow field polar coordinates and the initial ocean heat wave polar coordinates.

[0040] First, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are normalized. These coordinates are unified into a standard data interval, such as the [0, 1] interval. Through normalization, the differences between different data due to different dimensions or value ranges can be eliminated, making subsequent processing more convenient and accurate. After normalization, the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates are obtained.

[0041] Next, the rectangular coordinates of the intermediate flow field and the rectangular coordinates of the intermediate ocean heat wave are transformed from the rectangular coordinate system to the polar coordinate system. In the polar coordinate system, the flow field data and the ocean heat wave data are expressed in terms of the distance from the center of the mesoscale eddy (i.e., the radius) and the angle relative to the eddy center.

[0042] This representation method can directly reflect the relative position and distribution characteristics of flow field data and ocean heat wave data and the center of mesoscale eddies, and is more intuitive and effective for analyzing phenomena related to mesoscale eddies.

[0043] In one embodiment of the present disclosure, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are normalized to obtain the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates, which specifically includes the following steps: obtaining the effective radius of the mesoscale vortex; based on the effective radius, normalizing the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates to obtain the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates.

[0044] First, the effective radius of the mesoscale vortex is a characteristic parameter that can characterize the spatial scale and influence range of the vortex. For the initial flow field rectangular coordinates, let a certain initial flow field rectangular coordinate point be (x, y). When normalizing, divide the horizontal and vertical coordinates of the point by the effective radius of the mesoscale vortex. That is, the new horizontal coordinate , the new vertical coordinate , where R is the effective radius of the mesoscale eddy.

[0045] After this processing, the flow field data originally expressed in actual geographic coordinates is converted to a relative scale based on the effective radius of the mesoscale eddy. Similarly, for the initial ocean heat wave rectangular coordinates, let a certain initial ocean heat wave rectangular coordinate point be (m, n), and perform similar operations, that is, the new horizontal coordinate , the new vertical coordinate After normalization based on the effective radius, the initial flow field rectangular coordinates are transformed into the intermediate flow field rectangular coordinates, and the initial ocean heat wave rectangular coordinates are transformed into the intermediate ocean heat wave rectangular coordinates.

[0046] This normalization process enables the flow field and ocean heat wave data of different mesoscale eddies to be subsequently analyzed and processed at a unified relative scale, eliminating the problem of inconsistent data scales caused by differences in the size of mesoscale eddies, and laying a good data foundation for subsequent accurate research on the relationship between mesoscale eddies and ocean heat waves.

[0047] In one embodiment of the present disclosure, based on the initial flow field polar coordinates and the initial ocean heat wave polar coordinates, the target flow field polar coordinates and the target ocean heat wave polar coordinates within a plurality of preset angle intervals corresponding to the mesoscale eddy are obtained. This can be specifically achieved through the following steps: the initial flow field polar coordinates and the initial ocean heat wave polar coordinates are interpolated to obtain the target flow field polar coordinates and the target ocean heat wave polar coordinates within a plurality of preset angle intervals corresponding to the mesoscale eddy.

[0048] First, it is necessary to clearly define the division of the preset angle intervals. This division can be set according to the research purpose and the characteristics of the mesoscale eddies. For example, a 360° circle can be divided into multiple angle intervals at intervals of 10°, starting from 0° and ending at 360°. Such divisions help to analyze the flow field and ocean heat wave characteristics of the mesoscale eddies at different angles in more detail.

[0049] Next, the initial flow field polar coordinates are interpolated. Between the known polar coordinate data points, the flow field data values ​​corresponding to each new angle are determined according to the preset angle interval based on the selected interpolation algorithm (such as linear interpolation, spline interpolation, etc.). These values ​​include the polar diameter (i.e., the distance from the center of the mesoscale vortex) and the flow field velocity. Through interpolation, the target flow field polar coordinates of the mesoscale vortex within the preset angle interval are obtained.

[0050] Similarly, the same interpolation method is used for the initial ocean heat wave polar coordinates. Based on the existing polar coordinate data, the ocean heat wave polar diameter and intensity corresponding to each angle are determined within the preset angle range, thereby obtaining the target ocean heat wave polar coordinates. These coordinates can more comprehensively reflect the distribution and intensity characteristics of ocean heat waves at different angles of mesoscale eddies.

[0051] Through interpolation processing, more comprehensive, regular and research-oriented flow field and ocean heat wave polar coordinate data can be obtained within a specific preset angle range. These data provide a better and more reliable data basis for the subsequent in-depth analysis of the corresponding relationship between mesoscale eddies and ocean heat waves.

[0052] In one embodiment of the present disclosure, the correspondence between the mesoscale eddies and the ocean heat waves is obtained based on the target flow field polar coordinates and the corresponding flow field velocities, the target ocean heat wave polar coordinates and the corresponding ocean heat wave intensities corresponding to multiple mesoscale eddies. Specifically, this can be achieved through the following steps: for the same preset angle interval, the target flow field polar coordinates and the corresponding flow field velocities, the target ocean heat wave polar coordinates and the corresponding ocean heat wave intensities of multiple mesoscale eddies within the preset angle interval are averaged to obtain the average flow field polar coordinates, the average flow field velocity, the average ocean heat wave polar coordinates and the average ocean heat wave intensity; the correspondence between the mesoscale eddies and the ocean heat waves is obtained based on the average flow field polar coordinates, the average flow field velocity, the average ocean heat wave polar coordinates and the average ocean heat wave intensity.

[0053] First, for the same preset angle interval. Since multiple mesoscale eddies are involved, each mesoscale eddy has its own target flow field polar coordinates and its corresponding flow field velocity, as well as target ocean heat wave polar coordinates and its corresponding ocean heat wave intensity within the preset angle interval. By averaging the target flow field polar coordinates of multiple mesoscale eddies within this specific preset angle interval, an average flow field polar coordinate representing the overall characteristics of the angle interval can be obtained. For example, assuming there are three mesoscale eddies, within the preset angle of 11°, the polar diameter of the first vortex is r1, the polar diameter of the second vortex is r2, and the polar diameter of the third vortex is r3. After averaging them, the average polar diameter of the angle interval is obtained. . Since the angle is known, the average polar angle can also be obtained. The average polar diameter and the average polar angle can constitute the average flow field polar coordinates. Similarly, the flow field velocity within the angle interval is averaged, the flow field velocities corresponding to multiple mesoscale eddies are added and then divided by the number of eddies to obtain the average flow field velocity. The same operation is performed for the target ocean heat wave polar coordinates and the corresponding ocean heat wave intensity to obtain the average ocean heat wave polar coordinates and the average ocean heat wave intensity.

[0054] After obtaining these average values, the corresponding relationship between mesoscale eddies and ocean heat waves can be derived based on them. The average flow field polar coordinates and the average flow field velocity reflect the comprehensive flow field characteristics of multiple mesoscale eddies within the preset angle range, such as the average vortex radius, rotation speed, etc. The average ocean heat wave polar coordinates and the average ocean heat wave intensity reflect the average distribution position and intensity of ocean heat waves within this angle range. By comparing the relationship between these average values, for example, determining the angle range with faster average flow field velocity, whether its average ocean heat wave intensity also shows a specific change trend, the corresponding relationship between mesoscale eddies and ocean heat waves in spatial distribution and intensity changes can be obtained, which provides key information for obtaining the interaction between the two.

[0055] In one embodiment of the present disclosure, the correspondence between the mesoscale eddy and the ocean heat wave is obtained according to the average flow field polar coordinates, the average flow field velocity, the average ocean heat wave polar coordinates and the average ocean heat wave intensity, which can be specifically achieved through the following steps: converting the average flow field polar coordinates and the average ocean heat wave polar coordinates to determine the target flow field rectangular coordinates and the target ocean heat wave rectangular coordinates; visualizing the target flow field rectangular coordinates, the target ocean heat wave rectangular coordinates, the average flow field velocity and the average ocean heat wave coordinates to obtain a visualization graph; the visualization graph represents the correspondence between the mesoscale eddy and the ocean heat wave.

[0056] First, the polar coordinates of the mean flow field and the polar coordinates of the mean ocean heat wave are converted. Although the data in the polar coordinate system are helpful for the early analysis of the characteristics of mesoscale eddies, they have certain limitations in intuitive display and understanding. In order to present the results more clearly, the polar coordinates need to be converted into rectangular coordinates. Using the conversion formula between polar coordinates and rectangular coordinates, the target flow field rectangular coordinates are obtained after conversion for the polar coordinates of the mean flow field. Similarly, the polar coordinates of the mean ocean heat wave are also converted to obtain the target ocean heat wave rectangular coordinates. In this way, the data expressed in polar diameter and polar angle are converted into rectangular coordinates expressed in horizontal and vertical directions, which is convenient for subsequent display on a two-dimensional plane.

[0057] Then, perform visualization. The obtained target flow field rectangular coordinates and target ocean heat wave rectangular coordinates are visualized in combination with the average flow field velocity and the average ocean heat wave intensity. In the visualization process, a variety of chart forms can be used, such as determining the position of the flow field data point with the x and y values ​​of the target flow field rectangular coordinates, and using the size of the point and adding arrows to reflect the size and direction of the average flow field velocity. Determine the position of the ocean heat wave data point with the x and y values ​​of the target ocean heat wave rectangular coordinates, and use different colors to represent different average ocean heat wave intensities.

[0058] Through such visualization, the correspondence between the flow field characteristics of mesoscale eddies and the intensity of ocean heat waves at different spatial locations can be intuitively reflected. For example, the information in the figure shows that the average flow field speed is faster in some areas, and the average ocean heat wave intensity is also higher. The correlation between the spatial distribution and intensity changes of mesoscale eddies and ocean heat waves can be obtained, making this complex correspondence clear at a glance, providing researchers with an intuitive and powerful basis for analysis.

[0059] In order to better understand the above embodiment, a specific example is provided below for illustration: For example, take the data generated in the South China Sea region (latitude range: 0°-25°N, longitude range: 99°-125°E) with a time span from 1993 to 2022.

[0060] First, all flow field data and all ocean heat wave data in the area within this time span are obtained as initial flow field data and initial ocean heat wave data, respectively. At the same time, all mesoscale eddy data in the area and time span are collected, and anticyclonic mesoscale eddies (AE) and cyclonic mesoscale eddies (CE) are processed separately. Mesoscale eddy data include the center point position, the longitude and latitude of the outermost envelope, the effective radius, and the time of occurrence. The initial flow field data covers the initial flow field rectangular coordinates of each point in the flow field and its corresponding flow field velocity. The temporal resolution of the initial ocean heat wave data is daily, and the spatial resolution is 0.25°, including the initial ocean heat wave rectangular coordinates of each ocean heat wave and its corresponding ocean heat wave intensity.

[0061] Next, each mesoscale eddy data is traversed. In this process, the flow field data and ocean heat wave data at the same time as the mesoscale eddy are matched. Then, from the selected flow field data and ocean heat wave data at the same time as the mesoscale eddy, the data points within the longitude and latitude range of the outermost envelope are further selected to obtain the target flow field data and target ocean heat wave data. Specifically, this screening operation can be implemented with the help of the inpolygon function in Matlab.

[0062] Afterwards, the initial flow field rectangular coordinates and the initial ocean heat wave rectangular coordinates are normalized relative to the distance of the mesoscale vortex center. Specifically, the radial distance x and the latitudinal distance y in the rectangular coordinates are divided by the effective radius of the mesoscale vortex. After such normalization, the intermediate flow field rectangular coordinates and the intermediate ocean heat wave rectangular coordinates are obtained.

[0063] Then, the rectangular coordinates of the intermediate flow field and the rectangular coordinates of the intermediate ocean heat wave in the Cartesian coordinate system are converted into data in the polar coordinate system, thereby obtaining the initial flow field polar coordinates and the initial ocean heat wave polar coordinates.

[0064] Based on the initial flow field polar coordinates and initial ocean heat wave polar coordinates, interpolation operations are performed at intervals of 11° within the circumference of the mesoscale eddy. These polar coordinates are interpolated to the preset angle range to finally obtain the target flow field polar coordinates and target ocean heat wave polar coordinates.

[0065] Subsequently, the target flow field polar coordinates and target ocean heat wave polar coordinates corresponding to all mesoscale eddies are averaged. For each identical preset angle interval, the target flow field polar coordinates and their corresponding flow field velocities, target ocean heat wave polar coordinates and their corresponding ocean heat wave intensities of multiple mesoscale eddies within the preset angle interval are averaged to obtain the average flow field polar coordinates, average flow field velocity, average ocean heat wave polar coordinates, and average ocean heat wave intensity.

[0066] Finally, the pol2cart function of Matlab is used to convert the polar coordinates of the mean flow field and the polar coordinates of the mean ocean heat wave to determine the rectangular coordinates of the target flow field and the rectangular coordinates of the target ocean heat wave. The rectangular coordinates of the target flow field, the rectangular coordinates of the target ocean heat wave, the mean flow field velocity, and the mean ocean heat wave intensity are visualized to obtain a visualization diagram, which can intuitively characterize the corresponding relationship between the mesoscale vortex and the ocean heat wave. For example, Figure 2 and Figure 3 The following visualizations show the relationship between AE and CE and ocean heat waves. The horizontal and vertical axes represent the x-axis and y-axis of the rectangular coordinate system, respectively. The size of the arrow represents the size of the flow field, and the direction of the arrow represents the direction of the flow field. Different colors represent the different intensities of ocean heat waves from 1.51 to 1.57. Figure 2 From the visualization shown, it can be concluded that the flow field in AE rotates clockwise, transporting warm water in the south of the west to the north, making the northwest a high temperature center (the area with the strongest marine heat wave intensity, i.e. the yellow area in the figure). Figure 3 From the visualization shown, it can be concluded that the flow field in CE rotates counterclockwise, transporting seawater in the southern part of the east side to the north, causing the northeast to become a high temperature center.

[0067] This method effectively overcomes the difficulty of data synthesis caused by the spatial asymmetry of mesoscale eddies by converting the flow field data and ocean heat wave data corresponding to the rectangular coordinate system into the polar coordinate system, and realizes the standardized integration and analysis of multi-vortex data. Specifically, the polar coordinate conversion is used to unify the vortex data of different positions and sizes into a coordinate system with their respective centers as the origin, eliminating the influence of spatial dislocation. In the polar coordinate system, interpolation is performed according to the preset angle interval to form a regular array, so that the multi-vortex data can be synthesized and counted. Finally, through the two-way conversion of polar coordinates and rectangular coordinates, the geometric meaning of the physical characteristics of the vortex is retained, and an intuitive visual display is achieved, which provides technical support for the accurate prediction and forecast of the occurrence and intensity changes of ocean heat waves, and thus contributes to the protection and restoration of marine ecosystems.
