RISPerformance 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 ...
TRMM LIS Climatology of Thunderstorm Occurrence and Conditional Lightning Flash Rates
Publisher: American Meteorological Society
Abstract: he Lightning Imaging Sensor (LIS) on the Tropical Rainfall Measuring Mission (TRMM) satellite has previously been used to build climatologies of mean lightning flash rate across the global tropics and subtropics. This new ...
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 ...
Kinematic and Microphysical Significance of Lightning Jumps versus Nonjump Increases in Total Flash Rate
Publisher: American Meteorological Society
Abstract: hirty-nine thunderstorms are examined using multiple-Doppler, polarimetric, and total lightning observations to understand the role of mixed-phase kinematics and microphysics in the development of lightning jumps. This ...
TRMM Observations of Intraseasonal Variability in Convective Regimes over the Amazon
Publisher: American Meteorological Society
Abstract: This study utilizes the Tropical Rainfall Measuring Mission (TRMM) satellite precipitation radar (PR), lightning imaging sensor (LIS), and passive microwave imager (TMI) data together with ground-based lightning data to ...
C-band Dual-Polarization Radar Signatures of Wet Downbursts around Cape Canaveral, Florida
Publisher: American Meteorological Society
Abstract: Wind warnings are the second-most-frequent advisory issued by the U.S. Air Force?s 45th Weather Squadron (45WS) at Cape Canaveral, Florida. Given the challenges associated with nowcasting convection in Florida during the ...
Insight into the Kinematic and Microphysical Processes that Control Lightning Jumps
Publisher: American Meteorological Society
Abstract: detailed case study analysis of four thunderstorms is performed using polarimetric and multi-Doppler capabilities to provide specificity on the physical and dynamical drivers behind lightning jumps. The main differences ...
Variability of CONUS Lightning in 2003–12 and Associated Impacts
Publisher: American Meteorological Society
Abstract: hanges in lightning characteristics over the conterminous United States (CONUS) are examined to support the National Climate Assessment (NCA) program. Details of the variability of cloud-to-ground (CG) lightning characteristics ...
Classification of Tropical Oceanic Precipitation using High-Altitude Aircraft Microwave and Electric Field Measurements
Publisher: American Meteorological Society
Abstract: During the 1998 and 2001 hurricane seasons of the western Atlantic Ocean and Gulf of Mexico, the Advanced Microwave Precipitation Radiometer (AMPR), the ER-2 Doppler (EDOP) radar, and the Lightning Instrument Package (LIP) ...
