Fig. S1: Comparison between the longwave radiative heating rate and surface sensible heating rate in cold pool regions, using the Ev=1 experiment at t=4 days + 1 hour and showing the 100 km x 100 km southwest corner of the domain. (a) The total radiative heating rate (shortwave plus longwave) vertically averaged from 0 to z=281.6 m (the lowest four model levels), which is roughly the cold pool height (half the mixed layer depth). The nonuniform vertical grid spacing is considered using a trapezoidal integral. The air density is assumed vertically uniform for simplicity. We find but do not show here that the lowest model level contributes a considerable positive longwave heating rate, but the 2-4th vertical levels contribute to negative longwave heating rate. (b) The effective sensible heating rate is calculated by dividing the surface sensible heat flux by z=281.6 m. In cold pool regions (where the surface sensible heating rate is anomalously high), the total radiative heating rate (~0.25 K/day) is much smaller than the effective sensible heating rate (~2 K/day).  

Ev_sub_X.zip: The CM1 output for experiments Ev=0.2, 0.5, 0.7, 1.0, 1.2, 1.5, 1.7, 2.0. Each zip file contains the .nc output file at t=2.5 days and t=4 days + 1 hour. 

postprocessing_codes.zip: The postprocessing codes. The script coldpool_size.m diagnoses the mean cold pool size and stores the result in R_array.mat. The script theory.m reads R_array.mat and calculates the cloud interaction length scale.
