| Abstract: | This article through to 1971～2007 year in September 5～ALaShan union area happened more than moderate rain precipitation weather spacetime distribution characteristics were analyzed.The analysis results show that(1).ALaShan union area above moderate rain precipitation time distribution features,interannual variability is not big,no obvious increase or decrease trend.Month border change obviously,from general started in May increase,enter after July is increasing rapidly,August to most,9 months and quickly reduce;(2).Space distribution features as:the northwest EJiNaQi for WoMeng moderate rain above precipitation at least area,bayan haot for moderate rain above precipitation days most areas,increased from northwest to southeast. |
