英文摘要

The energy budget of the Pacific Ocean is evaluated in the Super- Parameterized Community Climate Model version 4 ( SPCCSM4) on intraseasonal time scales. The budget terms are decomposed to isolate the MJO influence and the ocean current associated with Kelvin waves. Using this decomposition, one can distinguish between El Nino events with strong and weak MJO influence. Composites of El Nino events based on the wind power component associated with the MJO induced wind stress and oceanic Kelvin waves ( W MJO, K) are compared with composites based only on the atmospheric variability and based only on the oceanic variability. It was found that the composite of events when W MJO, K is near maximum (+ NMJO, K) shows a greater magnitude of mean perturbation wind power, buoyancy power, and available potential energy than any other case, which is consistent with the greater amplitude Kelvin wave perturbations on the thermocline, as well as the greater amplitude of SST anomalies at the peak of the event. For + NMJO, K, latent heat flux anomalies out of the ocean along the coast of New Guinea are seen coincident with deepening of the mixed layer depth there, suggesting that this is an important region for the thermodynamic influence of the MJO on the ocean. Latent heat flux anomalies into the ocean are seen across the ITCZ in the spring, suggesting a basin wide influence by the MJO on the ocean surface radiation budget in + NMJO, K.
