Applications of New Generation Weather Radar to Nowcasting and Warning of Severe Weather

Zhang Peiyuan Yang Hongping Hu shaoping(State Key Laboratory of Severe Weather,Chinese Academy of Meteorological Sciences,Beijing 100081)  
Making nowcasting and severe weather warning by New Generation Weather Radar need to Start from radar observations.Different weather systems must to use different methods of radar observations.Different observation methods and different forcast objects must to use different process methods of radar data for stressing echo characters.Nowcasting and severe weather warning are producted on the basis of radar echo analyses.Radar echo analyses need to grasp whole process of echo evolutions.Synoptic systems of impacting local weather are resolved according to the echo analyses.Severe weathers are distinguished with echo characters,future development trends of echo are understood by echo evolutions.For identified severe weathers with radar echos,signature recognitions and discerning means are built by the researches and the statistics of radar echoes.The main nowcasting method is the extrapolation,but the forcast experience is most important.The conclusion of the nowcasting is drawn by the forecasters based on their forecast experiences.Nowcasting technological processes needs to be formulated for better nowcasting and severe weather warning.
