辽宁人工增雨试验区最大连续降水量变化分析

Analysis of the Maximum Consecutive Precipitation Variation in Liaoning Artificial Precipitation Test Area

利用辽宁1961～2008年5～9月人工增雨作业季节的日降水资料,选出5～9各月中最大连续降水量作为基础,对人工增雨试验区最大连续降水量变化进行了分析。结果表明,近48年人工增雨试验区最大连续降水量各月周期不尽相同,但5、7、8、9月最大连续降水量的变化呈减少趋势,而6月呈增大趋势。

According to the daily precipitation data in artificial precipitation season during May to September from 1961 to 2008 in Liaoning Province,the maximum consecutive precipitation in the artificial precipitation test area was studied based on the maximum consecutive precipitation from May to September in 48 years.The results showed that the period of maximum consecutive precipitation in each month was different,and the variance trends of maximum consecutive precipitation in May,July,August and September were decreasing,while the variance trend of maximum consecutive precipitation in June was increasing.
