Abstract

The aim of this study was to explain the cause of the spacing of clouds along cloud streets and of along-roll disturbances within the convective boundary layer (CBI). The factors examined in detail include internal gravity waves, Kelvin-Helmholtz instabilities, shearing instabilities, and cross-roll instability. Radar analyses from NCAR's CP-3 and CP-4 radars during the Convection and Precipitation/Electrification (CaPE) Experiment were used. Simulations from the three-dimensional, dry version of the Clark cloud model were also used to examine rolls and along-roll features. Observation and preliminary results suggest that shearing instabilities were the most likely cause of the along-toll periodicities.
