Thanks to their 5 — year painstaking efforts, Chinese scientists have eventually completed the study of the genesis of China's severe climate disasters and associated prediction theory.

Being one of the first study topics selected by the 973 Program sponsored by the Chinese Ministry of Science and Technology, the study of the genesis of China's severe climate disasters and associated prediction theory has constituted a core content for the international study of climate variations and associated interactions (CLIVAR). The study has made an in - depth analysis of the changes and interactions of different spheres under the climate system, especially the changes and interactions of the sub— climate systems in east Asia and their impacts on the genesis of China s severe climate disasters. The study has resulted in a number of new theories relating to the genesis of China's severe climate disasters such as " Kast Asia Climate System", "F^ast Asian Monsoon - Warm Sink-ENSO Cyclic Interactions" and "Hateau Atmospheric Thermal Adaptability". Scientists have achieved new progresses in the study of ENSO cyclic mechanism and associated digital modeling, which greatly raised China's prediction capacity for F2NSO events. Scientists also established the digital prediction system for trans - seasonal climate abnormality and successfully predicted the severe drought and flood disasters occurred in the summers of 1998-2002.

In collaboration with the Marine Environment Prediction Center under the State Oceanic Administration, the study project had sponsored several rounds ot workshops on EL ININU events and co — sponsored with he Marine Environment Prediction Center and National Climate Center the seminar on China' s Severe Climate Disasters Prediction which successfully predicted the evolution of La Nina events during the period of 1999 — 2001, the occurrence of P2L NINO events in 2002 and the server droughts of north China in 1999 - 2002. The study has proposed the drought predictions for north China in the future 5—10 years, which provided scientific evidences for national economic planning and the sustainable development.
