Analysis of Tornado Monitoring and Warning Process by Phased Array Weather Radar
摘要
Abstract
As one of the important means of tornado monitoring and early warning,weather radar uses X-band dual polarization phased array weather radar system with ultra-high space-time resolution to better capture tornadoes and facilitate tornado early warning.This work chooses a tornado that occurred in Nanhai,Foshan at 07:00 on June 19,2022 to analyze the genesis and lysis of the tornado and the process of radar monitoring and early warning.With radar intelligent early warning software,the sensitive dual polarization and ultra-high space-time resolution data from X-band dual polarization phased array weather radar,real-time inversion of the three-dimensional wind field and analysis of tornado debris(TVS)characteristics can significantly enhance tornado monitoring and early warning.The tornado was successfully warned 18 minutes in advance in this case,which suggests that X-band dual polarization phased array weather radar is highly capable of strong convective weather detection.关键词
