Stochastic generation of subgrid‐scale cloudy columns for large‐scale models

Abstract To use the Monte Carlo Independent Column Approximation method for computing domain‐average radiative fluxes in large‐scale atmospheric models (LSAMs), a method is needed for generating cloudy subcolumns within LSAM columns. Here, a stochastic cloud generator is introduced to produce the subcolumns. The generator creates a cloud field on a column‐by‐column basis using information about layer cloud fraction, vertical overlap of cloud …
