摘要
本文在分析θ_se值的垂直分布廓线的基础上,提出了一种能清楚地解释对流运动强弱的指数——湿不稳定能量指数Cm;并用广州、海口两地1979～1983年5月份10层的温度、露点等要素,作实际计算和分析,发现大气对流层中存在5种类型对流形势,并初步分析了不同的对流形势下的Cm值与降水的关系。
Upon tne fundamental analysis of vertical distribution profiles of pseudo equivalent potential temperature, this paper presents an atmospheric moist labile energy index Cm which can clearly interpret the strong and weak convective mot- ions of atmosphere, and then the actual computation and analysis are made using the 10-level radiosonde reports of Guangzhou and Haikou in Mays during 1979- 1983. The results show: five typical comvective patterns exist in the troposphere; the relationship between Cm and precipitation in various convective patterns are analyzed primarily
