摘　　要：给出了Neyman-Pearson全局预报方法,以期在保持-给定虚警率的前提下提高预报率。增加了算法的实用性,使算法能够适合真实环境。该方法用于海洋风暴潮预报,能够较好地平衡预报率与虚警率间的关系。In this paper, a Neyman-Pearson overall forecast method is developed to improve the forecast rate on the promise of keeping a given false warning rate. This forecast method is more practical and can he suited to the actual environment. This method has been used to forecast the marine storm surge, and it is shown from the forecast results that the method can coordinate the balance between forecast rate and false warning rate.
