Abstract: The paper aims to study the evolution of Nanjing local climate dynamic system, the cloud cover, temperature and precipitation data with dimensionless treatment in Nanjing during 1951-2013 were used to built Nanjing local climate model by using inverse model method, and a preliminary physical interpretation of all coefficients of Nanjing local climate model was conducted. The study showed that: the change of cloud cover index was related with cloud cover index, precipitation index and square of precipitation index; the change of temperature index was related with temperature index, cloud cover index, precipitation index and square of temperature index; the change of precipitation index was related with precipitation index, cloud cover index and square of precipitation index. By studying the evolution of local climate model using each 30-year data, it was found that the coefficient of the nonlinear part had a decreasing trend, and the models of 1961-1990 and 1962-1991 showed a mutation in square of precipitation index in cloud cover and precipitation change equations. In linear part, it kept stable near climate state.
