Based on the correct short-range numerical forecast for climatic situation the accuracy is about 70%using statistical interpretation forecast method, and if the abnormal variation of mean monthly circulation could be predicted, the trend of abnormal frequency variation could be predicted.

在短期气候数值形势预报准确的基础上，应用统计释用预报方法所得的准确率为70%左右，若能预报出汛平均环流的异常变化，则可确定ATC汛频数的特多年或特少年。

Thirdly, Southeaster anomalies was favorable to TCs landfall over China with southeast-northwest path.

3异常东南风环流有利于引导生成的热带气旋以西北路径西行进入我国沿海并登陆。

Results show that, in this process, there is a specific circulating current accompanying with twin typhoons, the easterly air current north of them and southwesterly air current south of them are transporting water vapor, its transport effects are very different at vary evolution stages of AERE, to contribute to the peculiarity of water source for this process of typhoon.

结果表明，本次过程由于伴随着双台风特有的环流形势，其北侧的偏东气流和南侧的西南气流对水汽输送的作用，在台风"艾利"发展的不同时期存在很大的不同，形成了这次台风过程特有的水汽来源特点。

The analysis shows that the snowstorm occured under the large scale circulation background of two-trough-two-ridge over the Eurosian continent, and resulted from the coupling of the upper level westerly jet and the low level southwesterly jet.

研究表明：这次暴雪发生在两槽两脊的大尺度环流背景下，是高空西风急流和低空西南风急流上下耦合作用的结果。

The southwesterly low-level jets from the southern South-China Sea and the Bay of Bengal are main systems responsible for the maintenance in intensity of the typhoon and causing the enhancement of the accompanied heavy rainfall.

结果表明，在中高层出现"北槽南涡"的环流形势场有利于登陆台风的维持；源于南海南部和孟加拉湾的热带低空急流汇成的台风南侧的西南风急流是台风登陆后得以维持和引发暴雨增幅的重要系统。

When AACEF is weaker, the summer WPSH tends to be stronger with a southwestward extension, and the South Asia high will be stronger too.

3南半球Ferrel环流圈的异常使绕极低压带和副热带高压带的强度出现了反位相的变化特征，即南极涛动。

In order to understand the dynamic mechanism of the upwelling phenomenon,we used a three-dimension high resolution turbulent closure circulation model in spherical coordinates based on the modified ECOM_si model to study this upwelling.

为了解该上升流的动力机制，作者利用基于ECOM_si建立的一个水平球面坐标系的高分辨率湍流闭合的三维环流数值模式研究该上升流现象。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.

本文说明了天气图上的流场可以分解为旋转场和变形场：地转无摩擦的气旋、反气旋的涡旋型式是围绕中心点的闭合环流；考虑摩擦的气旋、反气旋的流型是围绕焦点的螺旋型式；鞍型场有4个涡旋中心点（2个气旋和2个反气旋）与1个鞍点；阻塞高压和切断低压由1个涡旋中心点与1个鞍点组成。

A design method of logic non-loop-current SR system is proposed in this paper.

提出一种逻辑无环流可逆调速系统的设计方法。

Cooperated with the circulation,the SST is very important for the formation of fog.

与大气环流条件相配合，海温场对海雾的形成是重要的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
