| 摘 要： | 根据辽宁地区的东北冷涡降水天气过程的规律和特点,利用气象台站网的常规观测资料,用事后划分影响区和对比区的移动分区区域回归方法,对东北冷涡降水云系的人工增雨作业效果进行了综合分析。结果表明:(1)辽宁省1992—2004年6~8月对东北冷涡云系人工增雨作业的平均增雨效果为22.44%。(2)有95%以上的可信度证明辽宁省的人工增雨有正效果。(3)物理检验分析证明,作业方法及催化部位基本是合理的,催化作业是有效的。

| Abstract: | Based on the regular and characteristics of precipitation processes of cold vortex in Northeast China and observational data of Liaoning meteorological observation networks,using the method of ROCMACS(Regression of Compartmentalization of Moveable Target and Control Areas after Cloud Seeding),the effect of artificial precipitation operation of cold vortex in Northeast China are comprehensively analyzed.The results are as follows:(1) The average precipitation enhancement effect in Liaoning Province during June and August from 1992 to 2004 is 22.4%.(2) The reliability over 95% prove that the artificial precipitation enhancement have positive effect.(3) The way and position of seeding is reasonable basically,and the seeding is resultful. |
