Modeling study of tropical nonsquall and squall clusters

A numerical cloud model in both two-dimensional and three-dimensional form is used to investigate the dynamical differences between non-squall and squall line convection in the tropics. Two-dimensional simulations with cold-pool dynamics indicate that the simulated convective system propagates as a slow-moving multicellular squall line, in contrast to the nearly stationary observed non-squall convective line. Environmental winds are not included in the two-dimensional simulations. To assess their effect on the behavior and general structure of non-squall convection, three-dimensional simulations are performed. In addition, oceanic squall lines are also studied.
