基于风廓线雷达资料的不同区域降水特征分析
Analysis of Precipitation Characteristics in Different Regions Based on Wind Profile Radar Data
摘要
Abstract
Tow wind profile radars (WPR)are used to detect six rainfall events at Nanjing and Dali.The re-turn signals which detected by WPR include information about ambient atmosphere and precipitation particles.The raindrop size distribution and Z-I relationship can be retrieved by return signal of precipitation particles.Atmos-pheric vertical velocity while rainfall can be calculated by return signal of ambient atmosphere.The results shows that (1)Raindrop size distribution retrieved by WPR can provide the basis for classification of precipitation type;(2)factor A in Z-I relationship changes at different stage and different intensity of rainfall.Though little change in index b while in the same area,significant differences happen between Dali and Nanjing;(3)throughout the at-mospheric precipitation process detected by WPR can provide technical support for short-impending prediction of precipitation.It makes sense to study of heavy rains and extreme precipitation events.关键词
