Fig. 2: The rain rate profiles under polluted (red curves) and pristine (blue curves) conditions with classified CAPE.

a, g, m Stratiform precipitation. d, j, p Convective precipitation. The shading indicates the standard deviation. And t-test for the differences between polluted and pristine conditions of (c, i, o) stratiform precipitation and (f, l, r) convective precipitation (the dashed line indicates the 95% confidence level at 100 degrees of freedom). The subplots take the logarithm of (b, h, n) stratiform precipitation rate and (e, k, q) convective precipitation rate for the upper levels and focus on the height/temperature of precipitation onset.
