Abstract: The relationship between convective scales in the pre-storm environment and Doppler measurements of divergence is discussed with attention to problems inherent in radar measurements. A method is suggested to minimize the ...

Abstract: Methods of statistical regression have been applied to single-radar radial velocity fields to map certain mesoscale (20?100 km) kinematic properties (e.g., divergence) of the convective boundary layer (CBL). Several methods, ...

Abstract: Dual Doppler-radars are used to obtain momentum flux and turbulence intensities in the cloudless convective boundary-layer (CBL) containing roll vortices. Momentum flux from small scales unresolved by the radar is determined ...

Abstract: Mean kinematic wind properties are obtained from the analysis of clear-air Doppler radar data along circles, a few hours prior to thunderstorm development. A variety of information is found to complement synoptic analysis. ...

Abstract: Satellite images that illustrate the clearing of cumulus clouds downwind from snow-covered areas are presented. The cloud clearing resembles that occasionally observed with lakes during warm advection, supporting the ...

Abstract: The effect of surface characteristics on the daytime change in the potential for development of deep convection resulting from surface flux of heat and moisture is evaluated by conceptual, scaling, and numerical modeling ...

Abstract: The new Doppler radars of the National Weather Service (i.e., the WSR-88D radars) are operated continuously in a volume scanning mode (called Volume Coverage Pattern, VCP) with the elevation tilt angles fixed for several ...
