相控阵天气雷达监测预警龙卷风的过程剖析.

As one of the important means of tornado monitoring and early warning, weather radar uses Xband 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.
