Dynamical-microphysical evolution of a convective storm in a weakly-sheared environment. Part II: airflow and precipitation trajectories from Doppler radar observations.

Abstract

Measurements from three Doppler radars of air motion and observations of the environment and storm reflectivity structure, supplemented by aircraft measurements of precipitation and cloud particles, are used to establish the dynamical framework for precipitation development in a convective storm that grew in a weakly-sheared wind environment. The moderately intense, evolving storm consisted of a series of cells that developed in late afternoon on 25 July 1976 in southeastern Wyoming. The storm, which moved along the sub-cloud wind direction, had a persistent but unsteady updraft region on its right forward flank. -from Authors
