Abstract: Some advances in Chinese Academy of Meteorological Sciences in climate and climate change research are reported, which include the recovery, reconstruction and processing of historical documents, the climatic zoning division, the variations of air temperature and precipitation in China, the features of air temperature and precipitation, the land-atmosphere process on the ground layer and the boundary layer, the heat source/sink and the ozone in the Tibetan Plateau, the simulation on paleoclimate, the theories and methods of predicting the climate change and the influence of the climate change on the society and the economy. In the recent 50 years, a lot of climate data are selected and "Precipitation Distribution Maps in China in recent 500 Years" is published. Wind energy resource zone is defined. It is confirmed that there are two warm periods in 1940s and 1990s and a relative cool period during 1950s—1960s. Under the context of global warming, the southwest region centered in Sichuan Province cools from 1950s until 1980s in China; the rainy zone shifts from North China to the middle and lower reaches of the Yangtze River. The synthetical physical image is indicated. The low value center of summer ozone in the Tibetan Plateau is found. The climate change features is simulated during the Tibetan Plateau apophysis. The monsoon circulation system in East Asia and its members are revealed. Many prediction methods are designed. The research achievements are also transferred to the economic development.
