Fig. 11
The average maximum convective available potential energy (CAPE) and convective inhibition (CIN) values of the rainfall process simulation results on July 21, 2012 (contour). The urban area is marked with a solid black horizontal line. The first row is the 1990 test and the second row is the 2010 test
