Attenuation of a 5-cm Wavelength Radar Signal in the Lahoma-Orienta Storms
Publisher: American Meteorological Society
Abstract: Attenuation problems arise when short wavelength radar is used for severe storm identification and structure analysis. These are illustrated by comparing observations from 5- and 10-cm Doppler radars. Reduced and fragmented ...
Velocity Distributions within Oklahoma Severe Storms
Publisher: American Meteorological Society
Abstract: Optimum design of a Doppler radar system for operation in a severe storm environment will depend on the maximum unambiguous velocity. Radial velocities of severe storms are examined from four Doppler radars over several ...
Streamwise Vorticity Effects on Supercell Morphology and Persistence
Publisher: American Meteorological Society
Abstract: The structure and steadiness of radar-observed supercell thunderstorms are examined in terms of their particular distribution of vorticity. The data confirm that the vorticity vector in supercells points in the direction ...

Observations Related to the Rotational Dynamics of the 20 May 1977 Tornadic Storms
Publisher: American Meteorological Society
Abstract: Observations of the 20 May 1977 tornadic storms are used to evaluate recent theories on the initiation of rotation at mid-and low levels and to verify recent thermodynamic retrieval results. Using the lengthy data record ...
Lightning Rates Relative to Tornadic Storm Evolution on 22 May 1981
Publisher: American Meteorological Society
Abstract: On 22 May 1981, we acquired lightning and Doppler radar data on two tornadic storms in Oklahoma. Cloud-to-ground lightning flash rates were measured with a magnetic direction-finder network, and total flash rates in the ...
