Based on the inspection and evaluation methods in Chapter 9 of GB/T 41165-2021'Methods for the Accuracy Inspection and Evaluation of Marine Forecast Results',this study assesses the accuracy of issued sea wave warnings in Shanghai coastal area during 2007‒2020,and analyzes the causes of false and missed warnings.Combining wave feature in Shanghai coastal area around each wave measurement point derived from historical long-term wind and wave data,spatial distribution of the waves with height above 2.0 m,and test result of the issued sea wave warnings,the criteria for issuing wave warnings in four coastal waters of Shanghai are proposed in a reasonable and scientific way.
