Mesoscale motion fields associated with a slowly moving GATE convective band.

Abstract

The structure of the convective band of 14 Sept in the dense GATE observing array is determined using wind and thermodynamic data primarily from multiple aircraft penetrations, which are well distributed in the vertical and in time. The structure and evolution of the line is similar to that of tropical squall lines, but it is less spectacular. Winds are weaker, there is less mass flow through the system, movement is slower, and there is less drying in the rain area. The line is aligned with the wind and shear, rather than across it, as is the case for many squall lines. -from Authors
