| 摘 要： | 本文利用贵阳市气象台2005和2006年5-9月的地面、高空观测和雷达资料等,分析了41次山地对流云并合形成积层混合云的降水过程.研究发现如果分散的多单体对流云若距离较近,则很可能出现大范围地跨接、合并,则有可能形成范围宽广的片状或带状云系,即积层混合云系.云系形成以后在移动的过程中,会将前方不断新生的对流单体合并,从而云系前缘强度增强,云系不断维持.整个系统的生命期往往较分散云团更长,并有可能会形成间歇性或连续性降水.本文分析了山地对流云并合形成积层混合云的一些具体特征.

| Abstract: | Using coordinated datasets of surface,radiosondes and radar of Guizhou province from May to September during 2005 and 2006,41 processes of convective clouds which mergered into convective and stratiform precipitation systems are studied.If the distance of convective clouds is near,the clouds tend to merge and lead to convective and stratiform mixed clouds systems.In the moving process of cloud system,new convective cells ahead are merged by cloud system,and then the system will be enhanced and maintained,so... |
