Abstract Condensation in cumulus clouds plays a key role structuring the mean, nonprecipitating trade wind boundary layer. Here, we summarize how this also explains spontaneous growth of mesoscale [> O (10) km] fluctuations and moisture around mean state minimal-physics, large-eddy simulation undisturbed period during BOMEX on large [ (100) domain. Small, spatial anomalies condensation cloud...

Abstract Horizontal organization or mesoscale variability is an important mechanism in the interaction of boundary layer with large-scale conditions. The development a precipitating cumulus trade wind studied using large-eddy simulations extensive horizontal domains, up to 160 × km 2 and fine grid resolution (40 m). cloud fields vary between different computational domain sizes. Mean profiles v...
