中文摘要:本文将江淮地区梅雨期的持性层探空资料和相应云区的增强显示红外云图参量值输入改进的一维半非常定暖云数值模式进行了数值试验。仅对其中三类不同降水强度的模式云的发生发展过程及其演变特征作了数值分析,并提出了一种用云模式的输出雨量(模式雨量)来预测梅雨锋降水量的简单方法。结果表明,本文云模式在研究梅雨锋降水性云的宏、微观结构和估算梅雨锋降水量等方面有一定使用价值。
 
NUMERICAL SIMULATION OF PRECIPITUS CLOUDS ASSOCIATED WITH THE MEIYU FRONT
Abstract:Radiosonde data at significant levels and parametric values of enhanced infrared images over the Changjiang (Yangtze)-Huaihe valley during the Meiyu(Plum Rain) season are fed into an improved time-independent one-and-one-half dimension warm cloud model. Formation and development of only three types of model clouds of different precipitation intensities are numerically analyzed. A simple method of using the output model rainfall to forecast Meiyu frontal precipitation amount is suggested. The results are found to be of significance in the study of the macro-and micro-structures of the precipitus clouds associated with the Meiyu front as well as in the estimation of its rainfall amount.
