Responses of CO_2 in surface water in subtropical West pacific to El Nino event

摘要

In order to investigate the relationships between the change of T_CO_2, △P_co_2 and SST, cur- rent, upwelling and biological activities during E1 Nino event in the subtropical Pacific, the responses of T_CO_2 and △P_CO_2 in surface water in the subtropical Pacific during E1 Nino and La Nina have been simu- Lated using a three-dimension carbon cycle model with biota pump. The results of numerical simulations Show that T_CO_2 in sea water increases with reducing of SST during mature phase of E1 Nino in the sub- Tropical West Pacific.
