…In addition to these, the selection of a route that will be the target value for the voyage route is also important. This route selection method has been called weather routing since the 1960s. This principle is based on three points: (1) creating a forecast wave chart from a weather chart, a forecast weather chart, and a wave (current state) chart; (2) applying the ship's speed characteristics for previously calculated waves (wave height and wave direction) to the forecast wave chart for the sea area including the starting point and the destination point to determine the speed at any given location for any given course; and (3) selecting the shortest route among all possible routes. … *Some of the terminology that mentions "weather routing" is listed below.

…これらのほかに,航海の経路の目標値となる航路の選定が重要なものとしてあげられる。この航路選定法は,1960年代からウェザー・ルーティングなどの名称で呼ばれている。この原理は,(1)天気図,予想天気図,波浪(現況)図から予想波浪図を作成する,(2)出発点から到達点までを含む海域の予想波浪図に対して,あらかじめ求めておいた波浪(波高と波向)に対する船の速力特性を適用して,任意の針路に対する任意の場の速力を求める,(3)考えられる経路のうちもっとも短時間の経路を選ぶの三つに基づいている。… ※「ウェザー・ルーティング」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
