| 英文摘要 | Tropical zonally symmetric atmospheric warming occurs during enso's warm phase, and lags the equatorial east pacific sea surface temperatures (ssts) by 3-4 months. the role of the indian and atlantic oceans on the atmospheric delayed response has been pointed out by earlier studies. for 1951-2004, a regression analysis based on the observed sst data shows the western pacific has a similarly important role as the indian and atlantic. nevertheless, there is time mismatch of around 1-2 months between the zonally averaged tropical sst anomalies and the atmospheric temperature anomalies. it is expected that the tropospheric temperature should be controlled by diabatic heating forcing, which is sensitive primarily to sst anomalies over regions of high climatological sst, rather than to the tropical mean sst anomalies. to describe this mechanism, we propose a parameterization scheme of diabatic heating anomalies dependant on sst anomalies and climatological sst. the 1-2 month mismatch between tropical mean sst anomalies and air temperature anomalies is reconciled by the fact that the tropical mean heating anomalies are dominated by the sst anomalies over regions of high climatological sst, and lag the tropical mean sst anomalies by 1 month. the mechanism described by this parameterization scheme joins several physical processes of enso with reasonable time intervals. and the parameterized heating anomalies work better than the tropical mean sst anomalies for capturing the atmospheric temperature signal relative to enso. |
