Non-precipitating shallow cumulus convection is intrinsically unstable to length-scale growth

Condensation in cumulus clouds plays a key role in structuring the mean, non-precipitating trade-wind boundary layer. Here, we summarise how this role also explains the spontaneous growth of mesoscale (\(>O(10)\) km) fluctuations in clouds and moisture around the mean state in a minimal-physics,...
