Available in PDF, EPUB and Kindle. Book excerpt: Four severe thunderstorms were observed on a single day by the AFCRL 5.4-cm Doppler radar at Sudbury, Massachusetts. Quasihorizontal radial velocity information was used to construct maps depicting the mean within-storm flow at different elevation angles over a period of about 20 minutes. Well organized patterns in the velocity field showed either persistence or slow evolution in time throughout an appreciable range of height. The merits of this single Doppler method for the investigation of future outbreaks are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Information on airflow in six New England thunderstorms was obtained from quasi-horizontal observations by a single Doppler radar. Radial velocity fields in four of the storms showed well organized patterns throughout an appreciable range of height. Vertical cross sections of the horizontal component field, coupled with some reflectivity information, provided a basis for inferring regions where vertical motion was strong. Computed horizontal flow fields consistent with the observed component fields showed environmental flow basically through the storm except at mid-levels.

This book was released on 1997-01-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinematic, microphysical, and electrical characteristics of two multicell thunderstorms observed in northeast Colorado were investigated using single and dual Doppler radar and cloud-to-ground (CG) lightning data. These particular thunderstorms were chosen because of their generation of weak short- lived tornadoes and CG lightning dominated by positive flashes. Storm data was collected using the multiparameter, CSU-CHILL, and the National Center for Atmospheric Research (NCAR) Mile High Doppler radars. Various radar analysis methods were employed in an effort to infer origins of rotation, tornado formation mechanisms, and the storm structure responsible for the observed lightning patterns. Single Doppler techniques included multiparameter measurements, calculations of azimuthal shear, histogram analyses, a study of constant altitude and vertical cross-section data, and an examination of the unedited reflectivity and radial velocity fields. Dual-Doppler data was used to synthesize the three dimensional wind field.

This book was released on 1967 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical-incidence observations by Doppler radar of velocities in a thunderstorm reveal some regions in which the spread of velocities is unusually broad. The widths of the vertical velocity spectra are generally greatest along the edges of a major updraft, where the maximum shear in updraft speed also occurs. The observations indicate that turbulence is an important cause of the abnormally wide velocity spectra, and suggest the utility of Doppler radar measurements of the vertical velocity spectrum as an indicator of severe cloudy-air turbulence. Furthermore, vertical velocity spectra in the more convective regions of thunderstorms, where they may be seriously affected by turbulence and wind shear, probably give an exaggerated picture of the particle size distribution.
