In this study, the meteorological knowledge necessary for deciding the operation of a ship was examined from the marine accident survey and the previous studies. By the comparison with the mariner examination, we considered the meteorological education that mariners should newly acquire to prevent marine accidents. In the marine accidents, some were caused by phenomena on the mesoscale γ to β and some were caused by mariners’ misinterpretation of meteorological information. On the other hand, in the mariner examination, most of the questions were on the synoptic scale, and also there were no questions about the latest weather forecasting technology such as satellite images and numerical weather prediction. Based on the above results, it was concluded that maritime officer needs the knowledge of the latest meteorological observation and forecasting technology as well as the uncertainty of meteorological information based on numerical weather prediction models.
