Impact of ice microphysics on multiscale organization of tropical convection in two‐dimensional cloud‐resolving simulations

摘要: This paper documents the impact of ice microphysics on multiscale organization tropical convection as simulated in two-dimensional cloud-resolving model simulations. Results from simulations which apply warm-rain are compared with results a simulation includes processes presented previously this journal. In these simulations, moist and large-scale dynamics interact an unprecedented range spatial temporal scales, albeit within limited dynamical framework. general, is similar all although scale propagation speed convectively-coup led gravity waves different between The most striking differences mesoscale. feature mesoscale convective systems reduced stratiform component shorter life cycle than microphysics. These impacts consistent previous modelling studies organized convection. It hypothesized that influences selection waves. Moreover, vertical transport horizontal momentum affected well.
