中文摘要: 利用水平分辨率1°×1°经纬度的FY 2C卫星相当黑体亮度温度(TBB)网格资 料,探讨了2005年6月18—22日华南致洪暴雨过程中TBB的平均场分布特征及其演变 特点,以求得华南地区对流云带(团)生消与暴雨的内在联系。结果表明:TBB场能较直观 地反映暴雨过程中积云对流活动、降水的分布和强度特征,TBB低值带与华南地区强暴雨落 区有很好的对应关系;强盛的西南季风对华南地区强对流云系的生成、发展和维持起了主导作用;对流 云带(团)以缓慢东移为主,随着云带(团)TBB值降低,降水强度逐渐加大; TBB有明显的日变化,同时伴随着雨强的日变化。

Abstract:With the TBB data from FY-2C satellite and the hourly observed precip itation data,the TBB features of torrential rain causing flood in Sout h China from 18 to 22 June,2005 are studied.The results show that TBB can direc tly and quantitatively present the features of the intensity and distribution of the cloud sys tem with heavy rainfall. The torrential rainfall area is basically in the lower TBB band. The rainfall intensity increases when TBB decrease s. The daily variation of the rainfall intensity is in accord with that of TBB.The strong southwest monsoon plays a key role in the development and enhancement of the strong conve ctive cloud cluster in South China.
