Cloud and precipitation differences between two experiments. (a) Relative humidity differences (SubMesoE-MesoE) between 148.5° E and 151.0° E. Black lines denote the height of MABL. Horizontal distribution of (b) 8-day-mean middle cloud fraction and (c) 8-day-accumulated precipitation differences (SubMesoE-MesoE). In (a), gray stripes denote significant values at 95% confidence level based on the Student’s t test. In (b) and (c), grids with shading denote that the difference has past the Student’s t-test at 95% confidence level. Submesoscale SST transition causes an increase in the middle cloud and precipitation account.
