摘　　要：将ＮＯＡＡ－１１探测仪ＴＯＶＳ／ＭＳＵ－ｃｈ．２亮温，对照分析四川省（２０°－４０°Ｎ，９０°－１１０°Ｅ）境内１９８９年７月７日到１２日几次重复出现的中尺度云团发展和降水过程，得到两点看法：①ＭＳＵｃｈ．２亮温可能表示７００ｈＰａ附近中尺度天气的一种特征环境；②强中尺度对流云团可能在ＭＳＵ－ｃｈ．２亮温分布的相对低值到高值过渡带内强烈发展，有时偏向高值区出现降水天气．This note describes the preliminary use of brightness temperatures of TOVS/MSU-channel 2 on board the satellite NOAA-11 to show the Characteristic environment o1meso-scale phenomena which arise aIternately the convective precipitation process overthe region(20°N-40°N; 90°E-110°E)on 7-12 July 1989.The preliminary results are:(1)The brightness temperatures of the MSU-channel 2 contribute to the 700hPalevel of peak energy. It is possible to provide a certain characteristic environment of themeso-scale phenomena over the above mentioned region.(2)Cloud clusters with strong convection emerge possibly in a transition zone fromthe low value of brightness temperatures to the relatively high value,and rather strongprecipitation appears near the high value zone.
