RISLightning Scaling Relations Revisited
Publisher: American Meteorological Society
Abstract: Scaling relations connecting storm electrical generator power (and hence lightning flash rate) to charge transport velocity and storm geometry were originally posed by Vonnegut in the 1960s. These were later simplified to ...
A Diagnostic Analysis of the VVP Single-Doppler Retrieval Technique
Publisher: American Meteorological Society
Abstract: A diagnostic analysis of the VVP (volume velocity processing) retrieval method is presented, with emphasis on understanding the technique as a linear, multivariate regression. Similarities and differences to the velocity?azimuth ...
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 ...
The Tropical Convective Spectrum. Part I: Archetypal Vertical Structures
Publisher: American Meteorological Society
Abstract: A taxonomy of tropical convective and stratiform vertical structures is constructed through cluster analysis of 3 yr of Tropical Rainfall Measuring Mission (TRMM) ?warm-season? (surface temperature greater than 10°C) ...
Performance Assessment of the Optical Transient Detector and Lightning Imaging Sensor. Part I: Predicted Diurnal Variability
Publisher: American Meteorological Society
Abstract: Laboratory calibration and observed background radiance data are used to determine the effective sensitivities of the Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS), as functions of local hour and pixel ...
Horizontal Divergence and Vertical Velocity Retrievals from Doppler Radar and Wind Profiler Observations
Publisher: American Meteorological Society
Abstract: Vertical motion profiles can be diagnosed with the mass continuity equation using horizontal divergence fields derived from various single-Doppler radar techniques such as EVAD (extended velocity-azimuth display), CEVAD ...
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 ...
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 ...
Convection and Easterly Wave Structures Observed in the Eastern Pacific Warm Pool during EPIC-2001
Publisher: American Meteorological Society
Abstract: During September?October 2001, the East Pacific Investigation of Climate Processes in the Coupled Ocean?Atmosphere System (EPIC-2001) intertropical convergence zone (ITCZ) field campaign focused on studies of deep convection ...
