General Circulation features over the Northern Hemisphere in 2003 are analyzed. It's shown that the subtropical high at 500hPa over the western Pacific in the winter of 2002/2003 and the spring and the summer and the autumn of 2003 was stronger than normal.The 500hPa geopotential height anomaly was positive for most of the cases over the Northern Hemisphere in 2003. Both in the summer and autumn,the 500hPa geopotential height anomaly of Tibetan Plateau was positive. The East Asian monsoon was stronger than normal in July and August.The equatorial convergence zone was not more active than nomal.The SSTa in the eastern tropical Pacific was nomal in 2003. The results show that the anomalies of both the tropical Pacific sea temperature and atmospheric circulation would exert a significant impact on the weather and climate in China.
