Kinematic and Dynamic Aspects of the Harrah Tornadic Storm Analyzed from Dual-Doppler Radar Data
Publisher: American Meteorological Society
Abstract: The paper deals with a diagnostic study of the three-dimensional kinematic and dynamic structure of the Harrah tornadic storm. Wind fields were computed from data collected over a 28 min interval in four dual-Doppler radar ...
Evolution of Downdrafts and Rotation in an Illinois Thunderstorm
Publisher: American Meteorological Society
Abstract: This paper discusses multiple-Doppler radar observations of a non-severe Illinois thunderstorm occurring on 29 May 1978. The vertical wind shear was fairly rectilinear on this day with the storm motion being related to the ...
Statistical Objective Analysis of Dual-Doppler Radar Data from a Tornadic Storm
Publisher: American Meteorological Society
Abstract: The horizontal wind and reflectivity fields in a tornadic storm are investigated with dual-Doppler radar. Emphasis is placed on a statistical objective analysis technique of the Eddy-Gandin type for determining these fields ...
Explanation of Multimodal Doppler Spectra in Terms of Sub-Beam Scale Motions
Publisher: American Meteorological Society
Abstract: Vertical incidence Doppler radar observations of an evaporating ice crystal cloud revealed many multimodal Doppler spectra, with modes often separated by more than 1 m s?1, and unusually large variances. The observations ...
Doppler Radar Study of a Warm Frontal Region
Publisher: American Meteorological Society
Abstract: This paper presents a case study of the structure of a warm frontal region as deduced from Doppler radar observations. The precipitation occurring ahead of the surface warm front was banded. The dominant precipitation bands ...
Accuracy of Vertical Air Motions from Nadir-Viewing Doppler Airborne Radars
Publisher: American Meteorological Society
Abstract: This paper presents an analysis of the uncertainties expected in vertical velocities using a vertically pointing airborne Doppler radar which has a nadir or zenith-pointing beam. To examine the expected uncertainty, the ...
Dual Doppler Radar Coordination Using Nomograms
Publisher: American Meteorological Society
Abstract: A simple nomogram technique to facilitate dual Doppler radar data collection is presented. Equations and nomograms are developed for relating the position of a given target relative to two radars. The results are general, ...
Passive Microwave Structure of Severe Tornadic Storms on 16 November 1987
Publisher: American Meteorological Society
Abstract: Passive microwave observations using the Special Sensor Microwave/Imager are presented for severe tornadic storms in the lower midwestern United States on 16 November 1987. These measurements are compared with Geostationary ...
Comparison of High-Altitude Remote Aircraft Measurements with the Radar Structure of an Oklahoma Thunderstorm: Implications for Precipitation Estimation from Space
Publisher: American Meteorological Society
Abstract: Observations of an isolated group of Oklahoma thunderstorms from NASA's high altitude ER-2 aircraft are presented. These observations include passive radiometric measurements at frequencies in the microwave (92, 183 GHz), ...
Structure and Evolution of a Severe Squall Line over Oklahoma
Publisher: American Meteorological Society
Abstract: A squall line on 2 May 1979 developed in Oklahoma in proximity to a synoptic-scale cold front. This line is analyzed during its growth and mature periods using radar, satellite, sounding and surface data. Some of the cells ...
