Investigated is the relationship between ENSO events and global land annual precipitation in 1948—2000 with the latest global land monthly precipitation data(PREC/L),with Monte Carlo scheme used to test the results of composite analysis.It is found that global land annual precipitation reduced obviously in warm events in those areas such as equatorial Western Pacific,North China,equatorial Central America,north of Bengal Gulf and Nepal,Eastern Australia,west of India and south of Pakistan,east of Lena River and Western Europe and Wilks in Antarctic.In warm years,the areas with more land annual precipitation cover only Chile and Argentina of South American,Somali,Kenya and Tanzania in East Africa,Turkey,Iraq and Iran in Middle East,Libya and Algeria in North Africa,Namibia in Southwest Africa and Botswana and Zimbabwe in south of Africa.It is also found by the statistical test that the coverage of areas with less annual land precipitation during warm events is larger than those with more rainfall and that the change in rainfall is more remarkable.There are no evidences to show that the interdecadal variation in ENSO has significant impacts on the interdecadal variation in rainfall over the above mentioned areas.However,the influence of warm events after 1980’s on the drought in Eastern Australia and North China is more notable than which before 1980’s.
