Abstract: By use of the moving T test to do research on the interdecadal climate jump of the Northern Hemisphere sea level pressure.500 hPa height and North Pacific sea surface temperature,we found that in recent 50 years an obvious interdecadal climate jump existed at the late 1970s to the early 1980s.There is significant difference before and after the jump in terms of the Northern Hemisphere sea level pressure,500 hPa height and North Pacific sea surface temperature.Furthermore,the focus is then placed on the effect of the jump on temperature and rainfall in China.
