摘要
选取1996～1998年5个登陆福建的台风,分析其中尺度暴雨时空分布规律;并通过对数字化处理的逐时红外卫星云图的研究,揭示台风中尺度对流系统发生发展的云图特征。分析表明台风中尺度暴雨的强度与中尺度对流云团的最冷云区温度和面积密切相关,常出现在中尺度对流云团偏东侧具有云顶温度梯度密集、云顶温度等值线曲率较大、云团处在发展阶段这些云图特征的区域。
In this paper, the time and space distributive regularity of meso-scale storm in five selected typhoons which landed at Fujian from 1996 to 1998 has been analyzed. And from the every-hour digitized satellite infrared photographs, the features of the meso-scale. Convective system is studied when it broke out and developed. It indicates that the intensity of the meso-scale storm is quietly connected with the temperature and the area of the coldest-cloud cluster. The heavy rainfall usually emerged on the eastern side of the meso-scale convective cloud cluster where the cloud mass is developing and with a dense gradient and big curvature of isoline of the cloud top temperature.
