山东一次暴雨过程的云降水微物理特征分析
Microphysical Properties of Cloud and Precipitation During a Rainstorm Process in Shandong Province
摘要
Abstract
Taking the rainstorm that occurred in Shandong Province on 29 July 2013 as an example,micro-physical properties of cloud and precipitation were investigated by using the microphysical analysis method developed by Rosenfeld and the high spatial resolution data of MODIS polar satellite and the precipitation particle spectrum data collected by the THIES laser rain droplet collector in Zhangqiu.The analyses show that the cloud cluster for the rainstorm is composed of various clouds with different heights.Deep mixed phase growth and glaciation zones exist in the convective cloud above -1 0℃ and the initial temperature of glaciation growth is about -20℃.There is condensation growth,coalescence growth and mixed phase growth in systematic stratus clouds but no glaciations growth.The high rainfall intensity greater than 100 mm·h-1 occurs several times with maximum rain droplet concentration up to 104 ,and the extremely big drop is close to 8 mm.So,there is a close relationship between rainfall intensity and rain droplet number concentration.The diameter of raindrops big-ger than 2 mm is less than 1% of total concentration,but it is the vast majority of contribution to rain intensity. From the types of spectrum distribution,it can be seen that exponential distribution is less frequent,and multi-peak structure has the largest proportion.关键词
