The present invention provides a horizontal wind shear position judgment method, device, electronic equipment and storage medium, wherein, the method includes: acquiring multiple key points of high air pressure contours. Select multiple consecutive keypoints from multiple keypoints of upper air pressure contours. Wherein, the multiple continuous key points are any multiple continuous key points in the upper air pressure contour. Computes the curvature of intermediate keypoints from the coordinates of multiple consecutive keypoints. Wherein, the intermediate key point is a key point in the middle of multiple consecutive key points. The curvature of multiple intermediate key points of any number of consecutive key points constitutes the curvature of multiple key points of the upper air pressure contour. The curvature of multiple key points of the high-air pressure contour is compared with a predetermined threshold to obtain a comparison result. Select the specified segment from the upper air pressure contour. Wherein, the curvatures of the multiple key points included in the specified segment are all greater than the predetermined threshold. Uses the coordinates of the keypoint with the greatest curvature in the specified segment as the horizontal windshear location.
Description
technical field [0001] The invention relates to the field of meteorological technology, in particular to a method, a device, electronic equipment and a storage medium for judging the position of a horizontal wind shear. Background technique [0002] The air pressure contour is a closed line formed by connecting places with equal air pressure within a certain period of time on a planar map, which can show the distribution of high and low air pressure in space. Since the pressure contour is a curve, the curvature of the pressure contour at a certain point can be expressed by calculating the curvature of the pressure at that point. The curvature of a curve is the rotation rate of the tangent direction angle to the arc length at a point on the curve, indicating the degree to which the curve deviates from a straight line. A numerical value that mathematically indicates how curved a curve is at a certain point. [0003] Wind shear is an atmospheric phenomenon, that is, the chang...
