登陆台风雨滴谱特征观测研究

Observational Study of the Characteristics of Raindrop Size Distribution of Landfalling Typhons

中文摘要英文摘要

利用多台雨滴谱探测仪器(OTT-Parsivel)收集到的登陆我国的台风尼伯特、妮妲、天鸽和帕卡的观测资料,对登陆我国的台风系统的降水微物理特征进行了分析,发现登陆我国的台风尼伯特、妮妲、天鸽和帕卡有较为一致的特征。降水过程中都有4mm以上粒子出现,不同的台风降水过程中出现的频率不同,粒径在0.5-1mm之间的粒子数浓度最大。从雨滴谱随时间演变来看,当降水中小粒子浓度突然增大时,必然伴随着大粒子的出现和最大粒径的增大。各台风的平均谱均为较为平滑的指数分布。

he data used in this study is collected by several raindrop disdrometer(OTT-Parsivel) set in Guangdong and Fujian Provience.The analysis of the landfall typhon Nepartak,Nida,Hato and Pakhar is based on these observation data.The landfall typhon Nepartak,Nida,Hato and Pakhar have common features in raindrop size distribution.During the rainfall there is large raindrop size above 4mm appear in every typhon system. The number of particles for particles which has diameters between 0.5-1mm was the highest in different typhoons. Comparing the stratiform cloud precipitation and convective precptitation of typhoon system .Dm and log10Nw shows strong linear correlation and the fitting curve is different from the one that Bringi (2003) found for multiple stratiform cloud precipitation.It means that landfalling typhoons system has its unique physical structure.
