RISDuration of Convective Events Related to Visible Cloud, Convergence, Radar and Rain Gage Parameters in South Florida
Publisher: American Meteorological Society
Abstract: The time interval between initiation of surface convergence and the subsequent response of visible cloud growth to this convergence was examined for nine cases of convection that occurred over the FACE 1973 and 1975 ...
The Relationship between Total Area Divergence and Convective Precipitation in South Florida
Publisher: American Meteorological Society
Abstract: Total area divergence is related to area rainfall using data collected during the Florida Area Cumulus Experiment (FACE) 1975 field experiment over a network that covered 1440 km2. A convergence event is defined as a ...
Lightning during Two Central U.S. Winter Precipitation Events
Publisher: American Meteorological Society
Abstract: Network-detected cloud-to-ground lightning coincident with mainly frozen precipitation (freezing rain, sleet, snow) was studied over the central United States during two outbreaks of arctic air in January 1994. During the ...
An Eight-Year Lightning Climatology of the Southeast United States Prepared for the 1996 Summer Olympics
Publisher: American Meteorological Society
Abstract: The 1996 Summer Olympics will be held in the Atlanta, Georgia, vicinity and several other sites in the southeast United States between 19 July and 4 August 1996. This period coincides with the peak thunderstorm season, so ...
Cloud-to-Ground Lightning and Upper-Air Patterns during Bursts and Breaks in the Southwest Monsoon
Publisher: American Meteorological Society
Abstract: Convective bursts and breaks in the southwest U.S. monsoon are investigated in a lightning context because cloud-to-ground (CG) lightning is an excellent indicator of deep convection. Bursts and breaks are identified using ...
Diurnal Cloud-to-Ground Lightning Patterns in Arizona during the Southwest Monsoon
Publisher: American Meteorological Society
Abstract: Cloud-to-ground (CG) lightning shows great variability across Arizona from one year to the next as well as from one day to the next. Availability of moisture, location of the subtropical ridge axis, transitory troughs in ...
Evolution of the Kinematic Structure and Precipitation Characteristics of a Mesoscale Convective System on 20,May 1979
Publisher: American Meteorological Society
Abstract: The relationship of vertical motion to the occurrence of precipitation from the convective and stratiform regions of a mesoscale convective system (MCS) is presented. On 20?21 May 1979, an MCS developed over portions of ...
Lightning from Two National Detection Networks Related to Vertically Integrated Liquid and Echo-Top Information from WSR-88D Radar
Publisher: American Meteorological Society
Abstract: Two national cloud-to-ground (CG) lightning-detection systems were operating across the contiguous United States during 1993. These two networks are compared to each other and to WSR-88D radar information collected by the ...
The Diurnal Distribution of Lightning over North Florida and Its Relation to the Prevailing Low-Level Flow
Publisher: American Meteorological Society
Abstract: Six years (1989?94) of cloud-to-ground lightning data are used to examine the distribution of lightning across the Florida panhandle and adjacent coastal waters and its relationship to the prevailing low-level flow. Only ...
An Evaluation of WSR-88D Severe Hail Algorithms along the Northeastern Gulf Coast
Publisher: American Meteorological Society
Abstract: Software build 9.0 for the Weather Surveillance Radar-1988 Doppler (WSR-88D) contains several new or improved algorithms for detecting severe thunderstorms. The WSR-88D Operational Support Facility supports testing and ...
