| 摘 要： | 2°×2° mean monthly COADS grid data in 1974 and 1987 of E1 Nino and La Nina years are used to compute thesensible and latent heat fluxes,the net longwave radiation,the incident solar radiation and heat budget on the tropicalPacific surface(30°S—30°N).The difference of the heat budget between El Nino and La Nina mainly occurred on theequatorial ocean surface,especially the water area west of Ecuador and Peru.During El Nino,the sensible and latentheat exchange increased,the net longwave radiation and incident solar radiation decreased and the net gain(loss) of heatreduced(increased) on the ocean surface.During La Nina,the circumstances were opposite.Finally an ideal model ofair-sea heat exchange mechanism for the El Nino-La Nina cycle is summarized. Key words:El Nino,La Nina,air-sea heat exchange,COADS grid data

| Abstract: | 2°×2° mean monthly COADS grid data in 1974 and 1987 of E1 Nino and La Nina years are used to compute the sensible and latent heat fluxes,the net longwave radiation,the incident solar radiation and heat budget on the tropical Pacific surface(30°S-30°N).The difference of the heat budget between El Nino and La Nina mainly occurred on the equatorial ocean surface,especially the water area west of Ecuador and Peru.During El Nino,the sensible and latent heat exchange increased,the net longwave radiation and incident solar radiation decreased and the net gain (loss) of heat reduced (increased) on the ocean surface.During La Nina,the circumstances were opposite.Finally an ideal model of air-sea heat exchange mechanism for the El Nino-La Nina cycle is summarized. |
