On a 850 - hpa vorticity map , overlaid with streamlines , regions of strong positive vorticity are highlighted with colours to demarcate higher chance of unsettled weather 850百帕斯卡的涡度图，以颜色显示正涡度区域。配合流线，可以清楚标示坏天气出现机会较大的地方。
The elements of vorticity , divergence , specific humidity , moisture flux divergence and k index etc . were benefited to the form and development of storm rainfall over the rainfall region 降水区上空的涡度、散度、比湿、水汽通量散度、 k指数等要素有利于暴雨的形成和发展。
The different organizing of mesoscale cyclone and " convective line " makes the mcss difference in shapes with circular or belt , respectively . a kind of favorable synoptic environment for ma 脊轴，走向和水汽羽平行，同时水汽羽也和一条正涡度带相对应，其位置和走向均和低空es 。
Using a forced dissipative nondivergent nonlinear barotropic vorticity equation and by means of various schemes , we did simulation experiment and get its numerical solution 从强迫耗散无辐散正压涡度方程出发，用不同方案模拟试验得到它的数值解，它与已经导得解析解的特征较为一致。
( 5 ) based on the complete form of vertical vorticity tendency equation , the effect of spatially non - uniform heating on the formation and variation of subtropical high is discussed ( 5 )运用全型垂直涡度倾向方程理论，研究了空间非绝热加热在垂直方向的变化对副高强度和位置变异的影响。
The interaction of orograpic highs with tc is one of main mechanisms of deflection of tc track , so is the interaction of deviating vorticity dips which are induced by air passing by mountains , with tc 地形高压和由气流绕流产生的偏差涡度对与热带气旋之间的相互作用是导致热带气旋路径向南偏折的主要机制。
Different parameterization schemes have different influences on the maximum intensity of rainfall and the distribution of rain area . suitable boundary layer parameterization scheme has obvious improvement on simulated results 不同的边界层参数化方案对雨量中心强度、雨区分布、散度和涡度的预报均有一定的影响。
It was pointed out that the horizontal distribution of the moist available energy is helpful for heavy rainfall , and one of the enhanced mechanism of mesoscale low vertox is slantwise vorticity development 同时指出，湿有效能量的水平分布对于暴雨预报具有一定的指示意义，倾斜涡度发展是中尺度低涡加强的机制之一。
This anomalous non - uniform heating resulted in the powerful anticyclone vorticity locating in the south of yangtze river and western pacific , which lead to the intensive and westerly subtropical high 这种异常的非均匀加热状况导致我国江南到副热带西太平洋地区呈现带状的异常反气旋性涡度制造，使得6一7月副高偏强偏西。
It was noted in their studies that there exist two cases in initial vorticity field , with a single mesoscale vortex or several vortices which arrayed in one or two waves form in azimuthal 注意到在他们的工作中，初始场上中尺度涡一般是两种情况。一是单个中尺度涡旋，一是沿方位角方向的一波或两波分布的正、负涡度相间的几个中尺度涡。
