The invention discloses a strong convergence field recognition and speed
correction method based on Doppler
weather radar data, and the method comprises the following steps: designing a new coordinatesystem, converting radially distributed
radar data into grid
point data, and completing the extraction of a high-
reflectivity area; designing a detection template, and obtaining a parameter vector for describing the convergence intensity and position of a convergence point on the basis that the convergence point is located quickly; extracting a slave convergence point to generate a
convergence zone, and correcting the idea and
algorithm of the convergence intensity through the direction of the
convergence zone, thereby effectively solving a problem of the underestimating of the strong convergence field at a single
pitch angle and even the detection leakage; determining a profile line according to the strongest convergence point at the single
pitch angle, obtaining the better section of the strong convergence field, and obtaining the depth information of the strong convergence field. The method can achieve the automatic detection of the strong convergence field, solves the problems ofunderestimation and detection leakage to a certain degree through a speed
correction method, achieves the automatic drawing of the section map of the strong convergence field, achieves the calculationof the
feature parameter of the strong convergence field, and promotes the recognition and forecast of the convective weather disasters.
