摘要
收集2001、2002年5-10月副高控制下安徽省对流云个例.通过分析卫星云图上,对流云发生发展过程中云顶亮温、面积、几何形态等特征物理量的变化,来分析揭示这一天气背景下安徽省对流云特征.并通过分析对流云发生的地理位置,寻找对流云易发区.统计结果显示,在这一天气背景下,安徽省境内的对流云团中以在局地生消、短生命史的对流云为主.
The convective clouds are collected under Subtropical High from May to Oct. of 200t and 2002 in Anhui. Then the characteristics of some physical parameter e.g. TBB, area and figure are analyzed by using the GMS5 multi-channel data. The characteristics of convective clouds under Subtropical High are discovered. Finally the vulnerable areas of convective cloud are found through the analysis of the position of convective clouds It is shown that the short-time local convective cloud is the most cloud in anhui province under Subtropical High.
