英文摘要	Based on the large exchange of heat fluxes on the Earth's surface in the tropics, we propose that the lightning flash rate (LFR) is proportional to a product of the Bowen ratio and the sum of precipitation and evaporation rates. The proposed relationship is justified on the basis of the conversion of the kinetic energy of charging hydrometeors to the energy of flash discharges. However, the proportional relationship varies depending on the season. This product explains 90% of the variance in the monthly-averaged time series of the total LFR over our study area of 0° N-40° N and 60° E-120° E including south/southeast Asia and some part of southern China. The conversion efficiency is a maximum in the pre-monsoon season and minimum in the winter season. The total heat flux best accounts for the seasonal variation of the LFR.
