Sensitivity of idealized mixed‐phase stratocumulus to climate perturbations
Abstract Large‐eddy simulations (LESs) that explicitly resolve boundary layer (BL) turbulence and clouds are used to explore the sensitivity of idealized Arctic BL clouds to climate perturbations. The LESs focus on conditions resembling springtime, when surface heat fluxes over sea ice are weak, and...
