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.

Download or read book A Preliminary Report on Doppler Radar Observation of Turbulence in a Thunderstorm written by Ralph J. Donaldson and published by . 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.

Book excerpt: A penetrative flight by a T-33 aircraft was made through a large thunderstorm on 26 July 1960 over northern Arizona. From instruments recording airpla e accel r io, gl of t ck pitc a gle, preci e measure (! f / c) yielded a ver ical velocity every 60 ft of flight path. Calculated velocities differed from the true motions by a constant of integration. Evaluating the constant by alternate procedures produced two velocity distributions, differing from each other by a consta t.

This book was released on 1988 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this investigation were to determine the feasibility of deriving vertical velocity patterns, the magnitudes of those patterns, and the three-dimensional wind field in severe convective storms. A technique called Tracking Radar Echoes by Correlation (TREC), also called the NEXRAD Transverse Wind algorithm, and data from a single radar were used to determine the internal storm motions. The radar data were composed of Nature Severe Storms Laboratory (NSSL) Doppler data collected on 19 June 1980. TREC uses correlation analysis to determine motion within and around a given storm. TREC was used to determine the u and v wind components. These components were gridded using a standard objective analysis technique. It has been shown that in weak reflectivity regions random pattern matching can occur, therefore in areas of reflectivity less than 10 dBZ TREC-derived data were viewed with caution. Important results of this study are: 1) there was good agreement in both areal extent and magnitude between the TREC-derived vertical velocities and the dual-Doppler velocities; 2) for time increments of 5 min or less between radar volume scans, the horizontal wind field derived by TREC agreed with the dual-Doppler wind field during the multicell and transition phases of the storm; 3) the effects of the generator level motions on the TREC derived wind field were evident only in the supercell phase and; 4) vertical cross sections indicated regions of updrafts, storm-relative inflows especially in regions of updrafts, updrafts extending through a bounded weak echo region, and an apparent gust front.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical investigations are undertaken to relate intensity of turbulent air motion to Doppler radar spectrum mean and variance in precipitation environments. Examples of theoretical radar derived turbulence power density spectra and total precipitation motion variance show that effects due to imperfect particle response are significant for turbulence scale lengths less than 250 m. Doppler spectrum variance and estimated eddy dissipation rate (epsilon) are found strongly dependent upon precipitation environment for ranges less than about 20 km, and for cases where the turbulence outer scale length (lambda) is less than 0.5 km. They are also found to be essentially independent of lambda when the maximum pulse volume dimension is less than 1/2 lambda, and independent of range but strongly dependent on lambda at ranges where the maximum pulse volume dimension is greater than lambda. Estimation of epsilon by radar is shown to be unreliable until a method of remotely determining lambda is found. Nevertheless, classification of turbulence severity (index = cube root of epsilon is possible with only a reasonable guess of lambda. Analyses of aircraft/gust velocity data indicate that thunderstorm turbulence is localized into discrete patches, and that such localization must be accounted for when aircraft gust velocity data undergo power spectrum analysis.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to the current technology and application of radar in meteorology and atmospheric sciences Written by leading experts in the field, Radar Meteorology, A first Course offers an introduction to meteorological radar systems and applications, with emphasis on observation and interpretation of physical processes in clouds and weather systems. This comprehensive introduction to the subject offers an overview of the quantities essential to radar meteorology including the radar reflectivity factor, and Doppler, dual-polarization, and multi-wavelength radar variables. The authors highlight wind retrieval from single and multiple Doppler radars, precipitation estimation and hydrometeorological applications, with chapters dedicated to interpretation of radar data from warm season mid-latitude severe weather, winter storms, tropical cyclones and more. In addition, Radar Meteorology highlights research applications of this burgeoning technology, exploring dynamic applications such as space-borne and ground-based vertically pointing radar systems, and cloud, airborne and mobile radars. As meteorological radars are increasingly used professionally for weather observation, forecasting and warning, this much-needed text: Presents an introduction to the technical aspects and current application of radar as used in the meteorology and atmospheric sciences Contains full-colour illustrations that enhance the understanding of the material presented Examines the wide-range of meteorological applications of radar Includes problems at the end of each chapter as a helpful review of the contents Provides full instructor support with all illustrations and answers to problems available via the book’s instructor website. Radar Meteorology offers a much-needed introductory text to the study of radar as applied to meteorology. The text was designed for a one semester course based on the authors' own course in Radar Meteorology at the University of Illinois at Urbana-Champaign.
