There is basically a large cyclonic circulation system in the middle north area.

The superadiabatic state is frequently appears over the plateau, it would be favorable to the development of the cyclonic circulation.

高原上经常出现超干绝热现象，这将使得高原上的气旋性环流加强幅度比其他情况下更大；

The strongest cyclonic circulation and vorticity are at about 700 mb.

气旋性环流和气旋性涡度在对流层中层的700毫巴附近最强。

Results show as follows. The heavy rain taking place in the west side of Dabie Mountain is caused by β-scale cyclone on α-scale shear, and the heavy rain near the boundary area between Hunan and Hubei provinces is caused by cyclonic wind perturbation.

结果表明：（1）大别山西侧的暴雨由中α尺度切变线上中β尺度低涡造成，湘鄂交界地带的暴雨由切变线上气旋性扰动造成。

It is shown that the inner and outer regions of Tropical Cyclone have different governing equations. The inner region is governed by the cyclonic wind and an evolution equation, the outer region is governed by the gradient wind and another evolution equation.

研究表明，热带气旋内区和外区有不同的控制方程，内区受旋转风和一个演化方程制约，而外区受梯度风和另一个演化方程制约。

The reasons are as follows: the evolution of the northern cyclonic circulation system of the SCS mainly attributes to the existence and southbound extension of the cyclonic wind stress curl in the northwest of the SCS.

原因如下：南海北部气旋型环流系统的演变主要归于南海西北部气旋风应力涡度的存在和南扩。

The mid-scale shear, strong frontal zone, Mongolia cyclone and surface cold front were main influence systems of forming sand and dust storm.

中尺度切变线、强锋区、蒙古气旋和地面冷锋是引发沙尘暴的主要影响系统；

The results show that the frontal cyclone deepens rapidly by interaction with large-scale environment after occurring over ocean with weak hydrostatic stability;

气旋在弱静力稳定度的海洋表面启动发展之后，气旋与大尺度环境场相互作用，气旋得到迅速发展。

Tropical cyclone, frontal cyclone, cold high and southwest monsoon are the main synoptic systems affecting China Sea. When one of them controls the sea, the wave field on the sea has its own features due to the special wind field of this system.

影响中国近海的主要天气系统有热带气旋、锋面气旋、冷高压和西南季风，它们的风场结构很不相同，由此引起的海浪场也各具特点。

Finally, if the initial disturbance is located at the high-level, a situation like a cut-off low rather than a frontal cyclone will develop.

如果初始扰动位于对流层高层，则地面形成的气旋在结构上和切断低压类似，不像锋面气旋。
