长江三角洲地区区域气候模式的发展和检验
A REGIONAL SCALE CLIMATIC MODEL OVER THE CHANGJIANG DELTA:DEVELOPMENT, EVALUATION AND ANALYSIS
-
摘要: 利用区域气候模式对大尺度天气过程进行模拟, 分析了模式对多种降水过程模拟能力的差别, 对模式中的物理过程、积分步长对模拟结果的影响进行了简单的分析; 并利用模式模拟了长江三角洲地区地面特征改变对气候的影响。模拟结果显示, 长江三角洲地区植被退化、城市化面积扩大等因素会引起比较显著的局地气候变化。Abstract: A new regional climatic model was developed and proof-tested by simulating the frontal rainfall, cyclonic rain and shower.The effect of different physical processes and different time step in the model was analyzed in order to choosing the approopriate experimental project. Using this model simulated the climatic effect of the change of land-use in Changjiang Delta area.Result s show that vegetation reducing and urban extending are main causes of the regional climate change.The range of seasonal temperature would increase and the humidity would decrease if the vegetation reduced.With the urban area extending the urban heat island effect would be intense also.
