Fig. 7: The PTT-NSRR relationship from satellite observations and WRF simulated.

Satellite observed PTT-NSRR relationships for (a) stratiform precipitation and (b) convective precipitation under pristine (black dashed curves), polluted (black solid curves), and CAPE-corrected conditions (red solid curves). (c) WRF simulated PTT-NSRR relationships corresponding to the two microphysical parameterizations of Morrison (dashed curve) and Thompson (point curve). The t-test result of the difference between pristine and polluted conditions for (d) stratiform precipitation, (e) convective precipitation (red (black) line indicates the 95% (99%) confidence level at 100 degrees of freedom).
