Relationship among Subtropical Anticyclone, Drought and Earth Rotation

The deep reason of severe disaster weather with the relationship among the earth nutation, rotation and atmospheric change is explored based on the effective results about the disaster weather prediction of the long term made by the variation of the earth rotation in near 10 years. It is discussed the relationship between the subtropical anticyclone and subtropical easterlies to aim at the problem of high temperature and drought in the globe, further more, the comparison analysis has been made to the earth nutation and the variation of rotation. The research results show that the reasons of severe disaster weather not only are due to atmosphere itself, but have some variation information of earth movement which could be used for the weather forecast.
