%X In this paper, correlation analysis was used to analyse the relationship between the Earth's rotation ration and monthly mean 500hPa atmosphere circulation. The research results show that in the Earth's higher speed years, 500hpa polar vortex and India-Burma trough are filled, the Atlantic high , the North America high and the Atlantic Ocean-North America subtropical high are intensified and the location is inclined to north. In the Earth's lower speed years, 500hpa polar vortex and India-Burma trough are deepened, the Atlantic high , the North America high and the Atlantic Ocean-North America subtropical high are weakened and the location is inclined to south. The mechanism is that the variation of the Earth's rotation ration causes an additional centrifugal force. The force makes the atmosphere move in north-south , up and down directions. The movement of the air causes the general circulation to be changed.
