[0002] Wind profiler radar is an instrument used to measure the change of wind speed and direction in the atmosphere with altitude.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution 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.

[0046] In the present disclosure, in order to solve the above technical problems, based on the P-band wind profiler radar application terminal system, the quality mark is determined by RAD data time accumulation, RAD data analysis and single-time RAD five-beam spatial consistency check, single-time calculation of wind U, V, W components, and multi-time U, V, W time consistency averaging, and then the quality control of the processing of wind profiler radar radial data can be performed to ensure the quality of the processed data.

[0048] Figure 2 FIG. 4 shows a schematic diagram of a P-band wind profile radar application terminal system according to an embodiment of the present disclosure. Figure 2 As shown, the P-band wind profile radar application terminal system 200 may include a data processing and quality control module 201, a performance monitoring and analysis module 202, a product processing and display module 203, a radar control module 204, and a business operation module 205;

[0049] Among them, the data processing and quality control module 201 obtains and processes the power spectrum data based on the time resolution corresponding to the wind profile radar observation data; generates radial RAD data including five-beam radial velocity, spectrum width and signal-to-noise ratio based on the power spectrum data; performs a single-time RAD five-beam spatial consistency check on the RAD data; determines the horizontal wind U, V, and W components based on the radial velocity horizontal component obtained by the single-time RAD five-beam spatial consistency check; based on the horizontal wind U, V, and W components after removing outliers, performs multi-time U, V, and W time consistency averaging to generate horizontal wind speed, wind direction and vertical velocity, determine the corresponding quality mark and perform a vertical shear check;

[0050] Performance monitoring and analysis module 202, which performs key technical parameter monitoring, health index analysis, data upload and monitoring, and alarm information management based on radar operation status data, calibration data, and observation data;

[0051] Product processing and display module 203, used to read product data and display the product in a mirror image;

[0052] Radar control module 204, used for radar remote control and environment monitoring;

[0053] The business operation module 205 is used for system parameter configuration, business process management and authority management in the business process.

[0054] In some specific embodiments, the above-mentioned wind vertical products may include real-time wind vertical products, half-hourly wind vertical profile products, and one-hour wind vertical profile products;

[0055] The time resolution of real-time wind vertical products can be 6 minutes, so the corresponding specified time can be 00 minutes, 06 minutes, 12 minutes, etc. The RAD data time accumulation period can be pushed forward 18 minutes from the specified time to accumulate the RAD data within the time period;

[0056] The time resolution of the half-hour wind vertical profile product is 30 minutes. The specified time can be 00 minutes and 30 minutes. The RAD data time accumulation period can be pushed forward and backward by 15 minutes each from the specified time to accumulate the RAD data within the time period.

[0057] The time resolution of the one-hour wind vertical profile product can be 60 minutes, the specified time is 00 minutes, and the RAD data time accumulation period can be 30 minutes forward and backward from the specified time to accumulate the RAD data within the time period.

[0058] In addition, it should be noted that in order to ensure that the data within the time accumulation period is reported as soon as possible, the actual start time of accumulation can be delayed by 5 minutes, that is, the real-time product lags behind by about 5 minutes, the half-hour product lags behind by 20 minutes, and the hourly product lags behind by 35 minutes.

[0059] In some embodiments, the above-mentioned single-time RAD five-beam spatial consistency check on the RAD data includes:

[0060] Obtain radial velocities of five beams, east, west, south, north and center, from RAD data;

[0061] based on Determine the east, west, south, and north horizontal velocity components; where U E , U W 、V S 、V N are the east, west, south and north horizontal velocity components respectively, V RE 、V RW 、V RS 、V RN 、V RZ are the radial velocities of the five beams: east, west, south, north, and center, and θ is the tilt angle of the slant beam;

[0062] If the sum of the east and west horizontal velocity components, and the sum of the south and north horizontal velocity components are both less than the first preset threshold, the consistency check is qualified. That is to say, in this process, the east, west, south and north horizontal velocity components are used to judge the consistency of the five beams. If the atmosphere is completely uniform, then the east beam (south beam) and the west beam (north beam) are equal in size and opposite in direction, and the sum of the symmetrical components is zero. However, the real atmosphere is not completely uniform. When the real atmospheric disturbance is small, the sum of the symmetrical components is also small, which basically meets the atmospheric uniformity assumption. However, when the atmospheric disturbance is large, the values ​​of the symmetrical components are also quite different. Therefore, by setting the first preset threshold, it is possible to more accurately determine whether the consistency check is qualified.

[0063] The five-beam spatial consistency check is mainly performed on the unevenly distributed data during precipitation. There are two situations that will cause a large uneven spatial distribution of vertical velocity. One is that one of the two symmetrical beams is inside the precipitation cloud and the other is outside the precipitation cloud. The other is that the spatial distribution of precipitation particles in the convective cloud is uneven and the vertical velocity varies greatly. Therefore, the setting of the first preset threshold mentioned above is crucial.

[0064] In a specific example, Figure 3 Take the frequency distribution of all observation times Δu and Δv of low-mode and high-mode detection of a certain target observation station in China in March 2014 as an example, where Δu = U E +U W , Δv=V S +V N It can be seen that the tail phenomenon appearing at ±10m / s is mainly caused by the uneven wind in the detection space caused by precipitation. Therefore, the size of the first preset threshold can be set to 10m / s.

[0065] In the above embodiment, accurate east, west, south and north horizontal velocity components are determined based on the east, west, south, north and center five-beam radial velocities in the RAD data, and then the east and west horizontal velocity components are added, and when the sum of the south and north horizontal velocity components is less than the first preset threshold, the consistency check is qualified, thereby achieving accurate single-time RAD five-beam spatial consistency check of the acquired RAD data.

[0066] In addition, it should be noted that before performing a single-time RAD five-beam spatial consistency check on the acquired RAD data, RAD data parsing and format checking can also be performed. Specifically, the RAD data can be parsed according to the corresponding RAD data format description in the preset wind profiler radar general data format, and the correctness of the data format and the integrity of the data content can be checked. The correctness check of the data format includes the number of bytes and the total number of bytes of each item in the header file block, and the number of bytes, the total number of bytes, and the sub-modal symbol of each item in the data block; the integrity check of the data content mainly checks whether the content of each mode is complete. If the format is incorrect or the content is incomplete, the RAD is marked as an abnormal RAD and does not participate in subsequent operations.

[0067] In some embodiments, determining the horizontal wind U, V, and W components based on the radial velocity horizontal component obtained by the single-time RAD five-beam spatial consistency check may include:

[0068] When the values ​​corresponding to the five-beam radial velocities are all valid, the U and V components satisfy the formula:

[0069]

[0070] When four values ​​corresponding to the five-beam radial velocity are valid, the U and V components satisfy the formula:

[0071]

[0072] When three of the five-beam radial velocity values ​​are valid, based on the three-beam principle, according to the formula

[0073]

[0074] Calculate the U and V components of the horizontal wind.

[0075] In the above embodiment, the valid values ​​corresponding to the five-beam radial velocities are classified according to quantity, and then the horizontal wind U and V components under different conditions are calculated respectively, so that the calculated horizontal wind U and V components are more accurate.

[0076] In some embodiments, based on the horizontal wind U, V, W components after removing outliers, performing multi-time U, V, W time consistency averaging may include:

[0077] Based on the formula Determine the average consistency result, where E consensus is the average result of consistency, N max represents the maximum number of samples of the horizontal wind U, V, and W components after removing outliers, S j Represents the jth sample value in the array with the largest number of samples.

[0078] Specifically, the above consistency averaging method is an averaging method for multiple measurements of the wind profiler radar at the same height, which may involve three parameters: consistency averaging time, consistency window width and consistency sample threshold.

[0079] Assume that a beam is at the same height within the consistency averaging time and 10 radial velocity samples S1,…,S are measured. 10 , firstly replace S1 and S2,…,S 10 Compare them separately, and put the data whose difference is less than the consistency window width into array W1. Similarly, we can get data W2, ..., W 10 , select the array with the largest sample size, and calculate the percentage of the sample size in it to the total sample size. If the percentage is greater than the consistency sample threshold, it is said to have passed the consistency test, otherwise it is said to have failed the consistency test. The average value of all radial velocity data in the largest sample array is obtained as the average radial velocity measured at this height, which is the consistency average. Use N max represents the maximum number of samples that can be obtained after consistency check, S j represents the jth sample value in the array with the largest number of samples. The average result of consistency can be expressed as When performing consistency averaging on one hour of wind data, the data processing time may be, for example, 1 hour, the consistency window width may be set to 2 m / s, and the consistency sample threshold may be set to 4.

[0080] In the above embodiment, by combining the maximum number of samples of the horizontal wind U, V, and W components after eliminating outliers and the j-th sample value in the array with the largest number of samples, multi-time U, V, and W time consistency average calculations are performed, so that multi-time U, V, and W time consistency average calculations can be accurately performed to ensure the quality of data obtained by subsequent processing.

[0081] In some embodiments, the process of determining the corresponding quality indicator may include:

[0082] Determine the representativeness of horizontal wind and vertical speed based on the ratio of the time-consistent average sample number to the initial sample number;

[0083] Based on the representativeness of horizontal wind and vertical speed, the corresponding quality mark is determined.

[0084] In the above embodiment, the representativeness of the horizontal wind and vertical speed is determined by combining the ratio of the time-consistent average sample number to the initial sample number, and thus the corresponding quality flag can be accurately determined.

[0085] In some embodiments, Figure 2The system can also determine the up and down wind vertical shear index based on the height, horizontal wind speed and horizontal wind direction angle, and when the up and down wind vertical shear indexes are both greater than a second preset threshold, the corresponding horizontal wind is eliminated;

[0086] When the upwind vertical shear index is greater than the third preset threshold or the downwind vertical shear index is greater than the third preset threshold, the corresponding horizontal wind is eliminated.

[0087] Among them, the vertical shear index of up and down wind satisfies the formula V she is the vertical shear index of up and down winds, V H1 With V H2 are the upper and lower horizontal wind speeds, and are the upper and lower horizontal wind directions respectively, and hgt1 and hgt2 are the upper and lower horizontal wind heights respectively.

[0088] In some embodiments, the second preset threshold comprises 0.03 and the third preset threshold comprises 0.08.

[0089] In the above embodiment, the vertical shear check is achieved by determining the vertical shear index of the upper and lower winds and then eliminating the corresponding horizontal wind according to the rules.

[0090] In some embodiments, Figure 2 The system in can also be expressed as as well as Calculate the horizontal wind speed, wind direction and vertical speed; where, is the value of each component after time consistency average, V H is the horizontal wind speed, is the horizontal wind direction, W V The vertical speed can accurately determine the horizontal wind speed, wind direction and vertical speed, ensuring the quality of data obtained in subsequent processing.

[0091] In the above-mentioned P-band wind profiler radar application terminal system, the quality mark is determined through RAD data time accumulation, RAD data analysis, single-time RAD five-beam spatial consistency check, single-time calculation of wind U, V, W components, and multi-time U, V, W time consistency averaging, so that the quality control of the wind profiler radar radial data processing can be carried out to ensure the quality of the processed data.

[0092] In some embodiments, each modal data can also be spliced. The specific wind profile radar modal splicing method is: first low mode, gradually increase the height, select high mode data in the overlapping area of ​​low mode and high mode, until each mode is spliced ​​together. And the output data format can output the spliced ​​real-time / half-hour / one-hour product according to the preset wind profile radar general data format.
