A case study was carried out with a focus on applying the TIGGE (THORPEX Interactive Grand Global Ensemble; THORPEX stands for The Observing System Research and Predictability Experiment) precipitation forecasts for the hydrological users in Linyi, a region richest in rivers and reservoirs in east- ern China. The preliminary results exhibited great potential of improvement in applications of weather forecasts by combining the user-end information. Although the TIGGE results provided by existing na- tional/international operating models were independent from the user-end, the case study enlightened ways of establishing an iteratively self-improving UIFS involving user-orientation throughout the forecast process.展开更多
