摘要： 通过分析大气环流特征值与内蒙古草原蝗虫发生面积的关系,结果表明,上一年12月亚洲经向环流指数(IM,60E—150E)、当年3月亚洲区极涡强度指数、当年5月大西洋欧洲区极涡面积指数、副热带高压、东亚季风等与内蒙古草原蝗虫的发生面积具有明显的相关性,尤其在发生趋势上相关密切,说明这些大气环流特征值的强弱对内蒙古草原蝗虫发生有重要的作用。

Abstract: in this article,we have analyzed the relationship between atmospheric circulation andgras shopper occurrence area in Inner Mongolia. As the results, Asia meridional circulation index (IM, 60E-150E) in December last year, Asia polar vortex intensity index in March, Atl}ntir. Europe polar vortex areaindex in May, subtropical anticyclone and East Asia monsoon, all they had obvious and closely relativity with grasshopper occurrence area and occurrence tendency in Inner Mongolia, respectively. So, study on atmosphericcirculation characteristic is to help understand grasshopper occurrence. in Inner Mongolia.
