| Abstract: |
| In terms of observational analysis and numerical simulations,study is performed of the synergistic effects of the tropical Indian Ocean and Pacific SSTA on the atmosphere in northern winter.It turns out that the SSTA features show in-phase variation for the Indian Ocean and the central/eastern Pacific at low latitudes and anti-phase change compared with that in the neighborhood of the western Pacific "warming pool".When negative SSTA in the western Pacific and positive SSTA in the central/eastern Pacific and the Indian Ocean are available,the 500 hPa height anomaly exhibits a wave train of a positive-negative-positive anomaly following a great-circle path emanating from the subtropical western Pacific via the NW portion to North America,with enhanced westerly jet over midlatitude East Asia and the NW Pacific,and v.v.The comparison to the results from the numerical modeling of the tropical western Pacific SSTA reveals the importance of the synergistic effects of the oceans on atmospheric circulations. |
