Probing a Nonprecipitating Cold Front with Doppler Weather Radar
Publisher: American Meteorological Society
Abstract: The utility of Doppler radar to study boundary-layer kinematics of a weak nonprecipitating cold front in Oklahoma on 16 October 1987 was examined with measurements from two radars. Diagnosis was impeded by operation at low ...
Estimation of Divergence in the Prestorm Boundary Layer
Publisher: American Meteorological Society
Abstract: An analysis technique to derive wind field parameters from single-Doppler velocity measurements, known as Modified Velocity-Volume Processing (MVVP) is examined from both theoretical and operational perspectives. For this ...
Considerations in Estimating Horizontal Wind Gradients from an Individual Doppler Radar or a Network of Wind Profilers
Publisher: American Meteorological Society
Abstract: Applications of Doppler weather radar data to the analysis of wind fields are reviewed. Radial velocity measurements from a single radar are used to estimate horizontal wind vectors within small azimuthal sectors using two ...
Meteorological and Astronomical Influences on Radar Reflectivity in the Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: Observations are presented of time-varying radar reflectivity during a partial solar eclipse in Oklahoma. The measurements from a radar of 10-cm wavelength, were obtained in the clear-air boundary layer. The reflectivity ...
Estimating Soil Wetness from the GOES Sounder
Publisher: American Meteorological Society
Abstract: In this note, the relationship between the observed daytime rise in surface radiative temperature, derived from the Geostationary Operational Environmental Satellites (GOES) sounder clear-sky data, and modeled soil moisture ...
Evidence of an Agricultural Heat Island in the Lower Mississippi River Floodplain
Publisher: American Meteorological Society
Abstract: The Mississippi River floodplain in the states of Arkansas, Tennessee, Mississippi, and Louisiana presents a readily discernible feature in weather satellite images. This floodplain appears in the spring and early summer ...
Evolution of GLM-Observed Total Lightning in Hurricane Maria (2017) during the Period of Maximum Intensity
Publisher: American Meteorological Society
Abstract: AbstractTotal lightning data obtained from the Geostationary Lightning Mapper (GLM) were analyzed to present a first glimpse of relationships with intensity variations and convective evolution in Hurricane Maria (2017). ...
Severe Thunderstorm Development in Relation to Along-Dryline Variability: A Case Study
Publisher: American Meteorological Society
Abstract: Long-lived thunderstorms were initiated during the afternoon of 26 May 1991 ahead of a dryline in northwestern Oklahoma. Various reasons for initiation in this particular along-dryline location are investigated through ...
Observed Effects of Landscape Variability on Convective Clouds
Publisher: American Meteorological Society
Abstract: Visible and infrared satellite images, in combination with detailed landscape information, suggest an appreciable effect of spatial variations in landscape on cumulus cloud formation over relatively flat terrain. These ...
A Case Study of Severe Storm Development along a Dryline within a Synoptically Active Environment. Part II: Multiple Boundaries and Convective Initiation
Publisher: American Meteorological Society
Abstract: A dryline that occurred on 16 May 1991 within a synoptically active environment is examined in detail using research aircraft, radar, surface, satellite, and upper air observations. The work focuses on multiple boundaries ...
