    Based on satellite infrared cloud pictures and surface rainfallobservational data, the distribution features of autumn precipitationcloud species affecting the arid and semi-arid areas in Northwest chinaare analyzed, and regression equations are established for estimating thediurnal precipitation in September-November. These equations can beused to estimate daily and monthly precipitation for the areas short ofdata. Results show that when diurnal precipitation is within the rangeof 1.0--15.0mm, errors will be small, but the opposite is true when itis within the range of 0.1--1.0mm or≥15.0mm. The estimated monthlyprecipitation values are generally in agreement with the distributiontrend of the observational data.

    The study of combining satellite and radar data for estimating precipitation on large-scale ismade.S.VISSR data is submitted from GMS of Japan,and radar data from Doppler radar in Chi-nese Academy of Meteorological Sciences,SMA.At first,satellite and radar data in their own co-ordinate system are converted into the Lambert projection coordinate system with two standardparallels:30°N and 60°N.A correlation matrix of the probability of precipitation correlated tobrightness temperature and albedo is yielded by statistics.The,the distribution of the estimatingprecipitation can be obtained by extending the correlation matrix over a designed large-scale.Twoexamples(July 23 and August 16,1989)are tested.

    利用日本 GMS 卫星的展宽数字云图资料(Stretched Visible and Infrared Spin Scan Radiome-ter)和中国气象科学研究院的 Doppler 雷达资料,综合卫星和雷达资料进行大范围降水估计的研究。首先把卫星和雷达资料从各自的坐标系中变换到公共坐标系——双标准纬线(30°N 和60°N)Lambert 投影坐标系中,以雷达资料作为判断降水的标准,统计得到降水概率与红外亮度温度及可见光反照率的相关矩阵。然后再把这一相关矩阵应用到一定的卫星探测的大范围中,得出降水区域分布的估计结果。用该方法对1989年7月23日和8月16日两个个例进行了估计计算。
