| Abstract: | Considering the non-uniform saturation of the real atmosphere,a diagnostic study of a torrential rain event is performed from the perspective of the anomaly of the generalized moist potential vorticity(GMPV) after introducing the generalized potential temperature into the thermodynamic frame of the real atmosphere. The results show that the anomaly appeared at mid-lower levels of the troposphere when the torrential rain happened.Analysis of the magnitudes and locations of maximum values of the tendency of t... |
