thermal vorticity

The results show that the dynamic functions of thermal advection, vorticity advection, coastal frontogenesis and air jet stream made great contribution to the explosive development of the cyclone.

结果表明，温度平流和涡度平流、沿岸锋生以及高空急流的动力作用对气旋暴发性发展有重要贡献。

Three new pumping factors due to baroclinic effects are derived in the solution of vertical velocity at the top of the boundary layer. The first is thermal wind deformation, the second, thermal wind vorticity, and the third, the cross term of thermal wind vorticity.

在边界层顶垂直速度的解中导出了三种由斜压效应引起的Ekmon抽吸新物理因子，即热成风形变、热成风涡度及热成风涡度交叉项等抽吸因子。

It is proved that, during thermal adaptation the baroclinic component of potential vorticity along the boundary of the heating region becomes negative and larger than the barotropic component, where the atmosphere becomes symmetrically unstable.

证明在热力适应过程中，沿着加热区的侧边界斜压位涡为负，且大于正压位涡，那里的大气出现对称不稳定。

The effect of atmospheric heating rate accounted for dominant status while the cyclone was weakening, but the effect of vorticity advection and thermal advection was secondary;

气旋减弱阶段大气加热率所起的作用占主导地位，涡度平流和温度平流作用较小；

Based upon potential vorticity theory, this paper investigates the feature of atmospheric motion as a result of diabetic heating, and stresses the principle of atmospheric thermal adaptation to external thermal forcing.

利用位涡性质，讨论了因非绝热加热导致的大气动力特征的变化，阐明了大气动力过程向外加热强迫适应的原理。
