Then the paper draws the conclusion that drought disaster of Guangdong Province has a close relationship with El Nino events. Out of 23 drought events, 17 times relate with El Nino events. In addition, the paper examines the influence on the drought disaster in Guangdong Province caused by different kinds of El Nino disasters.
