Abstract

This article presents a study of east–west regional contrast in lightning activity over India (8°N–35°N, 68°E–98°E) using monthly satellite-based lightning flash grid (0.5° × 0.5°) data for a period of 10 years (1998–2007). On the premise of nearly equality to land mass location for the Inter-Tropical Convergence Zone (ITCZ), India is divided in two regions – eastern and western – spanning the 79°E longitude line. The spatial variation of the east–west contrast shows that lightning flash rate density is higher over east-northeast India (30 flashes km−2 year−1). The lower elevation of the eastern region is an important factor in maintaining a maximum surface temperature contrast in regard to influencing the development of strong convection and thunderstorms, and hence high flash rate density. The results suggest that the hot and humid extensive land region of the ITCZ in the eastern region is more likely to lead to the development of thunderstorms and high flash rate density
