EL Nino 冬天以强烈的气象喷射气流和暴风雪穿越国家南部地区为特征，然而在镧镍为主的年份里，喷射气流是波状的。它给北部州县带来比往常情况下更多的暴风雪。

We examined the relationship between the jet stream and activity of synoptic-scale disturbance Q, which depicts intensity of synoptic-scale disturbance in a period of time, and the relationship between the jet stream and transient eddy heat flux.

通过分析急流与天气尺度波动活动量Q(用于描述某一时间段内天气尺度波动活动强弱程度)、热量涡动输送的关系，发现：在气候平均意义下，天气尺度波动活动量在6、 8月份较大，这意味着在这两个月中，天气尺度波动较为剧烈。

Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.

应用实测气象资料，结合卫星云图与多普勒雷达图像分析，对2007年7月19日到8月2日云南少有的7次强降水过程进行综合分析，结果表明：高低空的西南急流是重要的影响系统，西南急流的维持为持续性强降水过程提供了水汽、动量和不稳定能量的快速传递，高原切变线与西南急流的有利配置，是7次持续性强降水过程必不可少的条件；持续性强降水出现在500hPa水汽通量大值区和水汽通量散度辐合区；卫星云图上切变云带和副高外围云带在云南汇合，切变云带和副高外围云带维持、加强的过程与强降水落区的时空分布对应较好。
