cyclonic circulation

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 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；

There is a cyclonic circulation in the northern part of the SCS, and its strength and scope decrease with the depth increases.

在南海北部存在一个气旋性环流，这个环流的强度和范围随深度增加而减小。

There is a cold centre in this cyclonic circulation, and its position moves slightly the south with the depth increases.

该环流的冷中心位置随深度增加稍向南移。

The areal distribution of the cyclonic circulation with height of the experimental storms has also been measured, also agreeing quite well with the observed ones.

还测量了各层气旋性环流所占面积随高度的分布，与实况也相似。

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。

The northern SCS is dominated mainly by a cyclonic circulation system.

南海北部环流系统主要受气旋环流所支配。

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

中北部海区（北纬12度以北）基本上为&气旋式大环流系统；
