Abstract: By using the water-bearing numerical model, the real-time forecasting experiments were made from June to July to 1994. The results of conventional and cloud field forecasts were examined and analysed. The results show that: (1) the running of the water-bearing numerical model is stable and reliable, (2) the model has the capability to forecast the distributions of all kinds of water substances and their variations with time, and to forecast the macro and micro-structures of cloud system and cloud clusters and their cloud physical characteristics, and (3) the forecasting capabilities for weather patterns and meteorological elements, especially for precipitation, are comparable to the conventional forecasting models.
