摘　　要：选取2015—2016年广东深圳地区的强降水过程为研究对象,降水过程按照天气条件划分为西风带型、西南季风型和热带气旋型,利用Parsivel激光雨滴谱仪和雨量筒测得的数据对广东深圳地区降水的微物理特征进行分析,结果表明:在不同降水量级的情况下,激光雨滴谱仪与雨量筒测得的分钟雨量都具有较好的对应关系,表明激光雨滴谱仪能够适应深圳地区多暴雨的环境;热带气旋带来的降水小粒径雨滴密度最大,大粒径雨滴密度最小,整个降水过程较为绵密;西南季风带来的降水小粒径雨滴密度最小,大粒径雨滴密度最大,整个降水显得很急促;西风带型降水的特征则介于前两者之间。For the further study of precipitation microphysical characteristics in Shenzhen,The data from the Parsivel laser raindrop spectrometer and rain gauge are used to analyze the precipitation processes of2015 to 2016.It is found that in case of different precipitation grads,the Parsivel laser raindrop spectrometer has a good correspondence with the rain gauge in measuring minute rainfall,which shows that the Parsivel laser raindrop spectrometer can adapt to the heavy rain environment in Shenzhen.All precipitation processes are classified according to different weather conditions：westerly,southwest monsoon,and tropical cyclone precipitation.The spectral characteristics of the three types of precipitation processes are analyzed.It is found that in the condition of tropical cyclone precipitation,the density of small particles and large particles was the biggest and the smallest respectively,which indicates that the precipitation process was denser.However,in the condition of south west monsoon precipitation,the density of small particles and large particles was the smallest and the biggest respectively,from which we could see that the precipitation was very heavy.The characteristics of westerly precipitation were in between the first two.
