| 摘 要： | 在2000年3月14日飞机人工影响天气作业过程中，极轨气象卫星实时遥感探测提供了人工增雨情况的一些证据。分析了作业后催化剂扩散情况，并且就风对催化剂的输送，地面增雨效果进行了探讨。初步结果：（1）本次过程在作业1小时23分钟后，最大自由运动扩散宽度11km，催化剂自由运动扩散区约为2508km^2，在云顶形成约1505km^3的塌陷区。（2）卫星资料分析，风的输送作用区约为7500km^2，为自由运动扩散区的3倍，是催化剂扩散的主要因素。

| Abstract: | During the course of weather modification by airplane seeding on March 14,2000,the real time remote sensing data of a polar orbiting meteorological satellite produce the evidences for artificial precipitation enhancement.The catalyzer diffusion after the airplane flying is analyzed.The wind transportation for catalyzer and the effect of precipitation enhancement over the ground are discussed.The preliminary results show that:(1) after the course about one hour and 23 minutes,the maximum diffusion windth caused by the random movement is 11 km,the catalyzer's diffusion area of the random movement is about 2508 km2,and there is a sunk area about 1505 km3 in the top of the cloud;(2) According to the analysis of satellite data,the affected area by the wind transportation is about 7500 km3,it is three times as much as the diffusion area of the random movement.It is obvious that the wind transportation is the key factor of catalyzer diffusion. |
