The results showed that two different nature of the fog (radiation fog and advective fog) have their common features. They are both formed in the zonal circulation.The abundant water vapor and thermal conditions are supplied by the southeast wind in the middle boundary layer. However, there are obvious difference between them .

结果表明：两种性质不同的大雾有其共同的特征，都产生于纬向环流下；中层的东南暖湿气流为大雾的形成提供了充沛的水汽和热力条件。

A Scheme of simple radiative parameterization of ice clouds suitable for use in GCM model is presented.

文章提出了一种简单且适用于大气环流模式的冰云辐射参数化。

With the deeping of the trough and the westward moving of the tropical cyclone, the low level vortex and wind shear line extended along a southwest - northeast orientation over the Yangtze River. On the effect of high, middle and low latitude systems, a rainband in southwest - northeast orientation formed gradually.

随着阻塞形势的发展和热带气旋的西移北上，经向环流加强，主要影响天气系统——低空的低涡切变线沿西南－东北方向伸展，在高、中、低纬度天气系统的共同作用下，一条西南－东北走向的雨带逐渐形成。

On the other hand, when the tropical western Pacific is in a cooling state in spring, convective activities are weakened around the Philippines. In this case, there is an anticyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts westward, thus, the late onset of the SCSM can be caused. Moreover, when the tropical western Pacific is also in a cooling state, convective activities around the Philippines are also weak in summer, since the abrupt northward-shift of the western Pacific subtropical high is not obvious in mid-June and early July and it gradually shifts northward during its northward advance in this case, the East Asian summer monsoon rainband can be maintained in the Yangtze River and the Huaihe River valleys.

相反，当春季热带西太平洋处于冷状态，菲律宾周围对流活动弱，在这种情况下，南海上空对流层下层有反气旋性距平环流，西太平洋副热带高压偏西，从而使得南海夏季风爆发晚；并且，当夏季热带西太平洋也处于冷状态，菲律宾周围对流活动也很弱，在这种情况下，西太平洋副热带高压北进时，在6月中旬或7月初向北突跳并不明显，而是以渐进式向北移动，从而使得东亚季风雨带一直维持在长江流域和淮河流域。

The results show that when the tropical western Pacific is in a warming state in spring, convective activities are intensified around the Philippines. In this case, there is a cyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts eastward, thus, the early onset of the South China Sea summer monsoon can be caused. Moreover, when the tropical western Pacific is also in a warming state, convective activities around the Philippines are also strong in summer, since the western Pacific subtropical high abruptly shifts northward in mid-June and early July during its northward advance in this case, the abrupt northward-shift of the East Asian summer monsoon rainband from South China to the Yangtze River and the Huaihe River valleys is obvious in mid-June and this monsoon rainband again jumps northward from the Yangtze River and the Huaihe River valleys to the Yellow River valley, North China and Northeast China in early July.

分析结果表明：当春季热带西太平洋处于暖状态，菲律宾周围对流活动强，在这种情况下，南海上空对流层下层有气旋性距平环流，西太平洋副热带高压偏东，从而使得南海夏季风爆发早；并且，当夏季热带西太平洋也处于暖状态，菲律宾周围对流活动也很强，在这种情况下，西太平洋副热带高压北进时，在6月中旬和7月初存在明显的突跳，从而使得东亚季风雨带在6月中旬明显由华南北跳到江淮流域，并于7月初由江淮流域北跳到黄河流域、华北和东北地区。

The characteristics of the general circulation in winter,spring and summer, East Asian monsoon, summer rainfall and the distribution of drought/flood in China are discussed.

我国夏季降水和旱涝有明显差异的四种不同分布型可能与冬季所处 ENSO循环的不同阶段以及大气环流和东亚季风对它的不同响应有关。

Paper made certain to adopt measure active and reactive component of output power in order to modify output voltage amplitude and phase, then achieved eliminating circulating current and realizing current share.

确立通过采取检测输出功率的有功成分和无功成分，修正输出电压的幅值和相位的办法，达到消除环流的目的，实现均流控制。

Based on the composite analysis of the NCAR/NCEP reanalyze datasets, significant differences existing in ENSO-related atmospheric circulation anomaly in East Asia during pre- and post-shift periods may be responsible for the interdecadal variation of relationships between ENSO and surface air temperature and precipitation in China.

利用NCEP/NCAR再分析资料合成分析表明，在不同的年代际背景下ENSO引起的东亚中高纬度大气环流异常型发生了明显改变是ENSO和降水气温关系发生年代际变化的原因。

From rotational motion,the rotator blades in medium speed exert either impact force to molding

该机的主要工作原理是采用低速转动的刮板推动物料在机盆内形成环流运动，中

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。
