Regional variability in lightning activity over South Asia

Regional variability in lightning activity over South Asia

The regional variability of lightning activity over 10 different regions, selected with at least one major meteorological/topographical feature, of South Asia (8°N–36°N, 90°E–100°E) have been examined on all time scales from the data obtained from July 1995 to December 2013 from the Tropical Rainfal...

Beschreibung
Zusammenfassung:The regional variability of lightning activity over 10 different regions, selected with at least one major meteorological/topographical feature, of South Asia (8°N–36°N, 90°E–100°E) have been examined on all time scales from the data obtained from July 1995 to December 2013 from the Tropical Rainfall Measuring Mission satellite. A comparative study of the correlation coefficients calculated between lightning flash rate and convective parameters, aerosol optical depth (AOD) and topography for different regions is carried out. Impact of the progress of the Asian Monsoon on the spatio‐temporal variability of flash rate is also examined. Monthly‐averaged variations are annual at the regions >2,700 m in altitude and are semi‐annual at the regions
