In order to investigate the relationships between the change of TCO2, △PCO2 and SST, current, upwelling and biological activities during El Niño event in the subtropical Pacific, the responses of TCO2 and △PCO2 in surface water in the subtropical Pacific during El Niño and La Nina have been simulated using a three-dimension carbon cycle model with biota pump.The results of numerical simulations show that TCO2 in sea water increases with reducing of SST during mature phase of El Niño in the subtropical West Pacific.At the same period, the Kuroshio in this region was weakened, the zonal currents were divergence, the upwelling carried the water with high concentrations of CO2 to the sea surface, so both of TCO2 and △PCO2 in surface water were increased.But TCO2 and △pCO2 were decreased during La Nina period.These simulated results confirmed the observations in 1982/1983, 1986/1987, 1991/1995 and 1997/1998 El Niño events.
