Abstract: The trajectories of hypothetical dropsondes are calculated in thunderstorm circulations and resultant vertical wind speed profiles as a function of height are constructed for each of the sondes. Motion fields are a) ...

Abstract: Description is given of a technique for determining optimal storm (reference frame) motion based upon application of a dynamic-retrieval method to velocity datasets derived from multiple-Doppler radar observations. The ...

Abstract: The structure and mechanism for maintenance of the Great Plains squall line thunderstorm are studied through formulation of a two-dimensional, time-dependent numerical model. The environmental conditions known to be favorable ...

Abstract: Rainfall collected for the squall line case of 21 August 1972 in the St. Louis area has been analyzed for certain pollutants known to be present in urban air. To aid in the interpretation of these measurements a two-dimensional ...

Abstract: A method for retrieval of pressure and buoyancy distributions in deep convection is applied to Doppler radar data collected at two analysis times during the tornadic Del City (Oklahoma) thunderstorm of 20 May 1977. Change ...

Abstract: The dynamics of a mesoscale convective system that matured in central Kansas on 3?4 June 1985 is investigated based upon data from ground-based dual-Doppler radar and other sources. The system was distinctly three-dimensional, ...

Abstract: A method is presented for obtaining temperature and pressure perturbations within convective clouds using detailed in-cloud motion data as input. Initial testing of the iterative method indicates that it converges to a ...

Abstract: This study presents analyses of data collected in the vicinity of a cloud-free dryline that occurred in western Oklahoma on 24 May 1989. Observations reveal sharp contrasts across the quasi-stationary, north-south dryline ...

Abstract: On 19 May 1977, a severe squall line formed and moved through the National Severe Storms Laboratory observing network in Oklahoma, producing heavy rain, hail, strong winds, and tornadoes. The squall line is examined at two ...

Abstract: Mechanisms for maintenance of the strong convection along the leading edge of a broad squall line that occurred in Oklahoma on 19 May 1977 are investigated. The findings are based upon analysis of data from a surveillance ...
