Based on TOMS ozone data from 1978.11 to 1993.4 and surface data of China, relationships between ozone variation over polar and Tibetan Plateau areas and the variation of precipitation and temperature in China are investigated. Results indicate that the variation of precipitation and temperature in China is closely related to the ozone variation over polar areas in spring and Tibetan Plateau in winter, so ozone variation can be used to prognosticate the precipitation and temperature in some parts of China.
