Changes in east Asian circulation pattern are investigated by the most recent versions of coupled climate models, one a high resolution version of the CCSR/NIES/FRCGC model and the other an ensemble of 17 state-of-the-art models made available by the international modeling community. These recent model results appear to give more credence to the following aspects: weakened winter monsoon associated with the shallower and northeastward shifted planetary wave trough over the east coast of the Eurasian Continent and increased activity of east Asian monsoonal rain band in summer associated with the strengthening of anticyclonic cells to its south and north.
