The present invention provides a weather recognition method, device, electronic equipment and storage medium, wherein the method includes: selecting the first high-air pressure contour from the high-air pressure contour map; obtaining the first high-air pressure contour All local curvature maximum points; select a plurality of starting points from all local curvature maximum points in the first high-air pressure contour according to predetermined rules; Step 1, obtain the first tangent line of the starting point; Step 2, according to Obtain the second high air pressure contour at the starting point; Step 3, obtain the first contour arc according to the first tangent and the second high air pressure contour; Step 4, obtain the maximum curvature value of the first contour arc Local curvature maximum point; step five, use the local curvature maximum point with the largest curvature value of the first contour arc as the starting point, and return to step 1 to step 4; according to the starting point and the first contour arc Obtain the ridge line at the local curvature maximum point with the largest curvature value; perform weather identification based on the ridge line.
Description
technical field [0001] The invention relates to the technical field of environmental meteorology, in particular to a weather recognition method, device, electronic equipment and storage medium. Background technique [0002] The identification of trough and ridge lines is one of the most important information for judging the upper-altitude weather situation, and it is of great significance for the research and judgment of weather situation and weather forecast. The trough line refers to the line connecting the points with the largest cyclonic curvature of the isobaric (high) line and the lowest air pressure (or geopotential height) in the low pressure trough. Usually, the weather changes are more obvious near the trough line, so the trough line occupies an important position in the weather forecast. A ridge is a long, narrow area extending from high pressure. The airflow in the area near the ridge line diverges, and there is a sinking movement, and the weather is usually go...
