冬季北太平洋におけるウェザールーティング : 海象特性と予測指標

概要

In the previous report a procedure of weather routing in the North Pacific in winter is proposed, the aim of which is not to calculate the optimum route for each individual voyage but to forecast, at the time of departure of ships, the mean zonal index for the first and the last 5-day periods in any one of the three categories "high", "medium" and "low" and then to select the recommended route that is proper for the forecast index category. In this paper, the relation between the zonal index and the wave distribution in the North Pacific, which has been derived from one year's data and used as the basis of our procedure, is confirmed using data for three years. Some modification is made to the wave distribution model and the revised recommended routes corresponding to the new model are presented. Finally, the advantage of these routes is evaluated by numerical simulation.
