一般情况下海员是用目测法结合天气图大概地估计海浪的高低。到目前为止,还没有用专门仪器测得海浪高度的精确数据。为了确定目测的海浪高度同海浪的实际高度之间究竟相差多少,国外的一些海洋学家进行了大量的持续同步目测和仪器测量海浪高度的实验。结果他们发现,从小船上测得的 Under normal circumstances, seafarers use visual methods combined with the weather map roughly estimate the level of the waves. So far, no precise data on the height of the waves has been measured using specialized instruments. In order to determine the difference between the visual sea wave height and the actual sea wave height, some overseas oceanographers carried out a large number of experiments on continuous and simultaneous visual observation and instrument measuring the sea wave height. As a result they found that measured from the boat
