基于区域气候模式的江淮流域气候变化初探文献综述（Literature review of climate change in Jianghuai basin based on regional climate model） Literature review of climate change in Jianghuai basin based on regional climate model Abstract: climate change is paid more and more attention by governments and scientists all over the world, and regional climate simulation research has also developed rapidly in recent years. This paper introduces the characteristics of climate in Jianghuai region, reviews the development of the regional climate model RegCM, of other regional climate model and comparative analysis, summarize the results of Jianghuai basin climate change research, finally discussed the application prospect of the regional climate model in regional climate and forecast return and problems. Keywords: RegCM3, regional climate, climate change, Jianghuai Basin The earth is experiencing a significant change in global warming as a major feature, the average temperature rise, extreme temperature changes in a wide range, extreme climate events become increasingly frequent. But the traditional global circulation model and statistical significance of climate change based on the analysis of the data analysis is not good to meet people on the causes of climate change, climate change and future trend of diversity of demand, so the regional climate model based on the study of evolution of the climate gradually emerge. The Huaihe River Basin since ancient times meteorological disasters, how to respond to global warming, precipitation, temperature, runoff, evaporation and other meteorological factors and how to change these problems need to be further discussed. From this point of view, the study of climate change in Jianghuai basin based on regional climate model is of great significance to the ecological system, environmental protection and development and utilization of the region. 1. climate characteristics of Jianghuai Basin The Yangtze Huaihe River Basin refers to the Yangtze River and the Huaihe Ri
