Long-term precipitation prediction for reservoir operation based on global meteorological information

摘要

Various kinds of meteorological information that cover all over the world have been developed with advancement of observational techniques and computer resources in recent years. Information and statistics only in a river basin, however, is taken into account in actual water resources management; therefore, it does not get to optimal management based on the quantitative prediction of basin conditions in the future. Long-term prediction which is crucial especially for drought control is not taken into consideration in water resources management, because of the limitation of prediction accuracy. To overcome the situation where long-term prediction is not so applicable to reservoir operation, regression model for precipitation prediction is developed for application to reservoir operation taking advantages of global meteorological information in this paper.
