湿位涡对西南涡的斜压性加大有重要的贡献。
Wet potential vorticity had a great contribution to the stronger baroclinicity of the southwest vortex.
暴雨与湿位涡呈反位相相关，且在暴雨较强时相关性更好。
Rainstorm phase is the inverse of humidity potential vorticity, especially in severe rainstorm.
在对暴雨过程的湿位涡分析发现，暴雨区存在湿对称不稳定。
Through analyzing MPV during the heavy rainstorm process, it is showed that is wet symmetry instability above rainstorm area.
同时，在此过程中受水汽加热的影响，水平相当位温梯度减弱，负的斜压项减弱，使得总的湿位涡正值增大。
Meanwhile, by the influence of water vapor in the process of heating, the gradient of equivalent potential temperature weakened, and baroclinic term also declined, so the total MPV increases.
