Keywords:ENSO, meridional circulation, polar vortex

The El Niño-Southern Oscillation (ENSO) is the most dominant interannual climate variability in the Earth’s climate system, and its pattern is characterized as zonal east-west see-saw of oceanic and atmospheric conditions in the tropical Pacific, and their associated teleconnections in the atmosphere to the extra-tropics. In addition, various aspects of climate system variability associated with ENSO are observed. For example, (1)vertical distribution of sea sub-surface temperature, (2)global average temperature, (3)energy budget at the top of atmosphere, (4)available potential energy in the atmosphere, (5)atmospheric meridional circulation such as Hadley and Ferrel circulations, (6) sub-tropical jet streams, (7)wave activities in the extra-tropics, and (8) polar vortex. In the presentation, I will review these aspects of climate system variability associated with ENSO, and discuss related mechanisms.
