A Case Study of Cumulus Convection Over Land in Cloud‐Resolving Simulations With a Coupled Ray Tracer

We present simulations of cumulus convection over land with shortwave radiation computed by a Monte Carlo ray tracer coupled to the flow solver. Ray tracing delivers very realistic in-cloud heating rates and global horizontal irradiance fields. The necessary performance has been enabled raw power GPU computing from techniques for accelerating data lookup convergence. used case study grassland in Netherlands compare those conventional two-stream solver, test demonstrate that simulated cloud evolution is insensitive across wide range samples sizes tracer. Furthermore, produce surface patterns resemble observations strongly feed back clouds via locally enhanced heat fluxes.
