Abstract

In this paper, two indices have been defined. One is the circumpolar area index of north to the westerlies and the other is the intensity index of westerlies. It has been found that by using these two indices the zonal circulation in the Northern Hemisphere has several periodical oscillations and that the weather in China is closely related to the intensity and the northward or southward shift of the westerlies in the Northern Hemisphere.
