辐合

The EOF2 reveals that moisture flux convergence from northeast and southwest over Yangtze River Valley shows a slight increasing tendent from 1980's and it is consistent with the fact of more frequently occurred heavy rainfall over there.

EOF2的主要特征是从1980年代之后，来自东北和西南的异常水汽在长江流域辐合，导致长江流域降水增多。

The cold Australia land always corresponds to strong Australian High or frequent cold air activities,which is favorable to the formation of strong cross-equatorial flow;The cold underlaying surface to the south of channel always corresponds to weak Walker circulation,which is also favorable to the formation of strong cross-equatorial flow;The warm Indo-China peninsula and cold South China Sea,as well as the strong heat source near the Philippines,all can correspond to strong convergence zone in north hemisphere,which is favorable to the formation of strong cross-equatorial flow.

冷澳洲大陆通常对应强澳高或频繁冷空气活动，其有利于强越赤道气流的形成；通道南部下垫面偏冷通常对应弱Walker环流，其有利于强越赤道气流的形成；偏暖中南半岛下垫面—偏冷南海下垫面、菲律宾附近强热源多对应北半球较强辐合带，它们都有利于强越赤道气流的形成；弱越赤道气流对应的强迫因子及环流因子的特征则与上述相反。

这一复兴运动之深刻，使人感到处于明显解体和分歧中的社会学思想又趋向辐合。

The convergence between anomalous northerlies from the central northern Pacific and anomalous southerlies from northerneast Australian can trigger strong westerly anomalies over the central and eastern tropical Pacific and then cause El 〓 event.

EL 〓的爆发和维持需要中太平洋地区的来自南北半球的经向风辐合所引起赤道中东太平洋的异常西风，其中来自澳大利亚东北部的异常南风的作用更为显著。

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。

The wind convergence, mesoscale cyclone and vertical wind shear at lower levels may produce heavy rainfall. The mesoscale cyclone and vertical wind shear at middle and upper levels may produce strong downburst or hails.

低层水平风的辐合、中气旋、垂直风向切变等可以产生强降水，中高层的中气旋、垂直风切变可以产生下击暴流、冰雹等强对流天气。

The analysis of wind vectors from automatic surface observations shows that the mesoscale convergence line between the northerlies and the easterlies in lower troposphere is very important to the torrential rain , which determines the locations and timings of the torrential rain .

分析结果表明，在高杆塔情况下，降低冲击接地电阻对耐雷性能的改善效果不大；在中横担外侧加设辐合地线和上横担中部增设避雷线以及适当调整导线与上下横担之间空气间隙的距离可有效的改善输电线路的耐雷性能；在条件允许的情况下，建议降低杆塔高度。

Barely 6,000 feet, Mount Washington is the largest obstacle blocking this crush of weather, an atmospheric pinch point, a boulder in a fast moving stream that churns wind into white water.
