Abstract:The comparison between US NEXRAD and traditional radars in their warning capabality on local severe storms,tornadoes and flash flood is described. It shows that the warning capability is significantly improved with NEXRAD (WSR-88D) replacing the traditional weather radars (WSR-57). Although in China,tornado is much less frequent than that in US,a large improvement can be still expected in local severe storm warnings with the installation of new generation weather radar network.
