Description

Technical Field

[0001] The present invention relates to the field of health data technology, and in particular to a method and system for recommending graded coastal health and wellness activities based on meteorological grid forecasts. Background Art

[0002] With the aging of the population and people's increasing emphasis on healthy living, the healthcare service sector has ushered in development opportunities. In order to provide more personalized and precise healthcare services, it is particularly important to conduct in-depth analysis and understanding of users' behavioral characteristics, health status, and healthcare needs.

[0003] Traditional health care has many projects, which are mainly divided into outdoor and indoor. Indoor projects are almost unaffected by the weather, while outdoor projects are greatly affected by weather changes. The coastal areas have good weather and a comfortable environment, and have become the first choice for outdoor health care projects.

[0004] The "Meteorological Grid Forecast" is a grid-based weather forecast system designed to provide more refined and personalized weather services. Compared to traditional weather forecasts, the "Meteorological Grid Forecast" offers higher spatial and temporal accuracy, meeting the public's diverse needs for weather forecasts. A "Meteorological Grid Forecast" divides a geographic area into multiple small grids (typically 5 km x 5 km), with weather conditions within each grid independently forecast. This forecasting method provides more accurate weather information, covering small areas from large cities to towns and even specific locations. The "Meteorological Grid Forecast" is very detailed in space, dividing a city or region into multiple small grids, with weather conditions within each grid independently forecasted. Temporally, the "grid forecast" can provide forecasts down to three hours or even minutes, providing more timely weather updates.

[0005] However, since the coastal area is the junction of land and ocean, the temperature and wind speed changes in the coastal area are affected by the ocean. It is difficult for traditional meteorological grid forecasts to take the ocean into consideration, which makes the meteorological grid forecasts inaccurate. The main groups of health care projects are various elderly people, some of whom are afraid of wind, some are afraid of cold, and some are afraid of the sun. This leads to the coastal health care activities causing discomfort to the health care personnel. Therefore, there is a need for a method and system for grading coastal health care activities based on meteorological grid forecasts, which can make the temperature and humidity forecasts of meteorological grid forecasts more accurate according to the deep ocean water temperature, thereby improving the health care effect. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a method and system for graded recommendation of coastal health care activities based on meteorological grid forecasts, which can make the temperature and humidity forecasts of meteorological grid forecasts more accurate according to the ocean water temperature and thus improve the health care effect.

[0032] A method for recommending coastal health and wellness activities based on meteorological grid forecasts, including:

[0033] Select a location for coastal health and wellness activities on the seashore, obtain the location's weather grid forecast content, and obtain geographic information near the location. The geographic information includes the deep sea area 100-200m below sea level closest to the location, and obtain the water temperature of the deep sea area. ; Weather grid forecast content includes ultraviolet intensity, sea surface temperature within the weather grid , ground temperature , land surface temperature , horizontal distance L between land and sea within the meteorological grid, wind speed ;

[0035]

[0036] = + ,

[0037] ；

[0038] , is atmospheric pressure, is the acceleration due to gravity, is the dry air gas constant, is the homogeneous atmosphere height, is the thickness of the gas layer; is the vertical thermal diffusivity, is the time step, is the depth of the mixed layer; is the sensible heat exchange coefficient, is the height of the near-surface atmospheric mixing layer;

[0039] Correct surface water temperature based on UV intensity , Corrected surface air temperature and corrected wind speed After comparing the ultraviolet intensity, water temperature, air temperature and wind speed required by the health care personnel, health care activity programs are recommended to the health care personnel in a graded manner.

[0040] From the above description, we can see that by introducing the water temperature of the deep sea area and exploring the influence of deep sea water on the surface sea water temperature, air temperature and wind speed, the existing meteorological grid forecast is supplemented and strengthened, making the forecast more accurate. At the same time, the ultraviolet intensity is not affected by the deep sea water temperature, so no correction is required. By introducing the deep sea water temperature, the surface sea water layer predicted by the meteorological grid is added. As a correction term, when > hour, >0, it is predicted that the subsequent surface water temperature will increase under the influence of deep water temperature; on the contrary, it will decrease, reflecting the regulatory effect of ocean vertical heat exchange on surface temperature; and by introducing The time step is adjusted according to After adjusting the forecast results for different time periods, health care projects can be arranged according to the forecast results for different time periods; the ground temperature is affected by the sea surface water temperature and wind speed, so the corrected surface water temperature and wind speed Calculating the ground air temperature as a parameter can make the prediction of surface water temperature, ground air temperature and 10-meter wind speed more accurate, and thus can be more accurate when recommending different health care projects to health care personnel, avoiding the health care activities from being counterproductive due to inaccurate weather forecasts.

[0043] From the above description, it can be seen that through hierarchical recommendations, when all conditions are met, projects can be automatically screened for health care personnel without the need for manual checking one by one, thereby improving efficiency.

[0044] Furthermore, when there are multiple locations, each location is calibrated to obtain the UV intensity and corrected surface water temperature of multiple locations. , Corrected surface air temperature and corrected wind speed , and make graded recommendations after comparing them item by item with all health care labels.

[0047] =RH (1+k ( ));

[0048] Among them, k is an empirical value.

[0049] From the above description, it can be seen that by correcting the humidity, since the deep sea water temperature will also affect the humidity, it is also calculated together.
