General Circulation and Its Impact over the Northern Hemisphere in 1995

General circulation features over the Northern Hemisphere in 1995 are analysed. It is shown that the 500hpa subtropical high over the West Pacific was stronger than normal. Its ridge line moved southward in early summer and northward in mid-summer. Meridional circulation was developed in spring,blocking pattern was stable in early summer,zonal circulation was dominant in mid-summer in Asia. 500hpa geopotential height was higher in summer and lower in winter in Qingzang Plateau. 100hpa geopotential height was persistently higher at the low latitudes and lower in mid latitude,the South Asia high was stronger. The El Nino event occured in 1994 ended in March in 1995.
