RISA Total Lightning Trending Algorithm to Identify Severe Thunderstorms
Publisher: American Meteorological Society
Abstract: An algorithm that provides an early indication of impending severe weather from observed trends in thunderstorm total lightning flash rates has been developed. The algorithm framework has been tested on 20 thunderstorms, ...
Analysis of a Small, Vigorous Mesoscale Convective System in a Low-Shear Environment. Part I: Formation, Radar Echo Structure, and Lightning Behavior
Publisher: American Meteorological Society
Abstract: The evolution of a small, vigorous mesoscale convective system (MCS) over northern Alabama is described using Doppler radar, GOES satellite, surface mesonet, lightning, and sounding data. The MCS formed near noon in a ...
A Comparison of the Optical Pulse Characteristics of Intracloud and Cloud-to-Ground Lightning as Observed above Clouds
Publisher: American Meteorological Society
Abstract: The time-resolved optical waveforms at 777.4 nm and electric-field changes produced by intracloud and cloud-to-ground lightning flashes were measured above clouds from a U2 airplane (flying at a height of 20 km) at the ...
Regional Differences in Tropical Lightning Distributions
Publisher: American Meteorological Society
Abstract: Observations from the National Aeronautics and Space Administration Optical Transient Detector (OTD) and Tropical Rainfall Measuring Mission (TRMM)-based Lightning Imaging Sensor (LIS) are analyzed for variability between ...
Convective Tendency Images Derived from a Combination of Lightning and Satellite Data
Publisher: American Meteorological Society
Abstract: A technique is presented for generating convective tendency products by combining satellite images with observations of cloud-to-ground lightning activity. Rapid scan (5-min) infrared satellite images are used to define ...
An Assessment of the First- and Second-Generation Navy Operational Precipitation Retrieval Algorithms
Publisher: American Meteorological Society
Abstract: Rainfall estimates produced from the Special Sensor Microwave/Imager (SSM/I) data have been utilized operationally by the United States Navy since the launch of the first SSM/I sensor in June of 1987. The navy initially ...
Where Are the Lightning Hotspots on Earth?
Publisher: American Meteorological Society
Abstract: revious total lightning climatology studies using Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) observations were reported at coarse resolution (0.5°) and employed significant spatial and temporal ...
Combined Satellite- and Surface-Based Estimation of the Intracloud–Cloud-to-Ground Lightning Ratio over the Continental United States
Publisher: American Meteorological Society
Abstract: Four years of observations from the NASA Optical Transient Detector and Global Atmospherics National Lightning Detection Network are combined to determine the geographic distribution of the climatological intracloud?clou ...
Doppler Radar and Lightning Network Observations of a Severe Outbreak of Tropical Cyclone Tornadoes
Publisher: American Meteorological Society
Abstract: Data from a single Weather Surveillance Radar-1988 Doppler (WSR-88D) and the National Lightning Detection Network are used to examine the characteristics of the convective storms that produced a severe tornado outbreak, ...
Three Years of TRMM Precipitation Features. Part I: Radar, Radiometric, and Lightning Characteristics
Publisher: American Meteorological Society
Abstract: During its first three years, the Tropical Rainfall Measuring Mission (TRMM) satellite observed nearly six million precipitation features. The population of precipitation features is sorted by lightning flash rate, minimum ...
