Rain rate accumulative log - normal and Gamma distributions are calculated from 1991's hourly rain gauge data for 333 -gauge stations of China. By comparison, it shows that the Gamma distribution depicts are better than the statistic rain rate distribution. So, 1 -minitue accumulative distribution to every gauge station is derived from the piece-wise regedon results of Gamma distribution through half-empirical conversion coefficients. Prediction of rain attenuation to China earth-satellite links is made for different conditions. The data tmetment procedure and its results presented in the poper may be practical and useful in engineering desgn.
