Storm Contour Recgnition and Tracking Technology Based on Doppler Weather Radar

摘要：

Traditional storm identification gives a centroid coordinate position and uses a central point to express the storm cell, this method losses an important scale information of the storm.In this paper, a new method that includes centroid coordinate and contour is introduced based on storm cell characterizes and its movement.And this method is based on the WSR-88D Build 9.0 Storm Identification Algorithm and employs Fourier descriptors for storm cells matching and tracking.Finally, least squares linear extrapolation will be used to predict the storm cells position in the next time.
