1 results about "Shear line" patented technology

This invention discloses a method and system for wind shear line identification and movement path prediction based on two-dimensional wind vectors, belonging to the field of lidar meteorological detection technology. The method includes using a variational algorithm to invert radial wind speed data into two-dimensional horizontal wind vector field data; setting an orthogonal vector detection window to calculate the two-dimensional composite vector difference to filter vector shear feature segments; extracting the core points of vector abrupt changes to reconstruct the wind shear line to construct a comparison area; and determining the dynamic guidance zone driving the movement of each local shear line segment based on the two-dimensional horizontal wind vector field data within the comparison area. The spatial displacement vector is determined based on the average two-dimensional wind vector of the corresponding area of ​​the dynamic guidance zone, and the corresponding local shear line segments are translated, extrapolated, and spliced ​​based on the spatial displacement vector to output the future movement path trajectory of the wind shear line. This invention solves the problems of easy missed detection in one-dimensional radial detection and failure of wind shear line identification and movement path prediction in radar blind zones in traditional methods.
