- Abstract:
- Zhengzhou City is one of serious water shortage cities in China. In order to realize the change state of precipitation, and to provide the basis for the rational development and utilization of water resources, we applied ARIMA model to establish the ARIMA(2,1,2) model for the annual precipitation forecasting of Zhengzhou City. Some works including the data preprocessing, pattern recognition, parameter estimation and model checking have been done before the establishment of this model. The results showed that the forecast of ARIMA(2,1,2) model is exact, the relative error ranges from -6.36% to 0.49%. The model can be used for short-term forecast of annual precipitation.
