摘要
利用天山山区2001～2002年6～7月31次较强降水天气过程的实况资料和20个降水日的28例云系的711数字化雷达资料,对天山山区夏季有利于人工增雨的气象条件、雷达回波资料及探空资料,分析了影响天山山区降水的几种主要天气系统、各种系统下降水回波源地、性质、变化、移向移速等活动规律,归纳出相关雷达回波参数和判据,为今后山区高炮—火箭人工增雨作业提供了一些科学依据。
Based on data of 31precipitation wea ther and digital data of 28tim e cloud s from 711Radar in both June and July from 2001to 2002,the p aper analyzed the meteorological conditions and r adar data favourable for artif icial precipitation.The result showed that there are several main weather syste ms and the original positions,qualities,changes,mo bile speed and directions of precipitation echoes accompanied with various weather sy stems.In addition, Some radar echo p arameters and criteria were shown in this paper,which could o ffer some scientific basis for weather Modification.
