图10 WRF模式输出的不同高度上平均势能密度（a）和对流强度（b）随时间变化 （虚线指示不同高度平均势能密度达到峰值的时间,红色三角形对应对流最强时刻）

Fig.10 The change of average potential energy per unit mass （a） and convective intensity （b） with time simulated by WRF model at different heights （The dotted lines are the corresponding time with the peak value of average potential energy per unit mass at different heights, and the red triangle marks the moment for strongest convection）
