中文摘要:最近几年来,国内外一部分气象工作者经常提到一种有组织的中一小尺度的对流性天气系统,依据它们的形成机制和在卫星云图上的表现称之为中尺度对流复合体(MCC)[1]。1978年以来,在我国大陆上由卫星云图观测到的MCC很多。其中1979年4月12日,6月8日,7月12日,1984年4月4日在我国东南部大陆上出现的中尺度系统是一些较典型的例子(如图4e)。本文以1979年6月8日在豫鄂东部和苏皖地区出现的MCC为例,分析讨论它们的发生、发展和消亡的云图特征,初步分析探讨它们的结构。
 
A PRElIMINARY ANAlYSIS OF CHARACTERISTICS AND STRUCTURE OF MCC IN SATELLITE CLOUD PICTURES
Abstract:A systematic convective weather event called the MCC (Mesoscale Convective Complex) has been noted for its mechanism of formation and appearances in the satellite pictures by many meteorologists. A great number of MCC’s have been identified in the cloud pictures over mainland China since 1978. Typical cases are the ones occurred over East China on April 12, June 8, and July 12 of 1979 and April 4,1984. Cloud picture characteristics of the formation, development and dissination of the MCC over the eastern parts of Henan and Hubei and the provinces of Jiangsu and Anhui on June 8, 1979 are analysed and its structure is investigated.
