High-resolution model captures global atmospheric deep convection

Authors


Abstract

When moist air is mixed high into the atmosphere, a process known as deep convection, the motion can give rise to towering storm clouds. Deep convection is also an important process for balancing momentum and energy within the atmosphere. Atmospheric deep convection is a relatively small-scale physical process, with the motion spanning anywhere from 1 to 10 kilometers. Its effects, though, are globally relevant, dictating storm patterns and climatological changes. Modeling deep convection in a global simulation, then, is challenging because these small-scale processes need to be represented and tracked across the whole planet.
