NOAA GEFS Wave Prob API

概要

GEFS Wave Probは、波浪アンサンブルのばらつきを波浪確率に変換します。単一の予想波高を見るだけでなく、具体的な運用しきい値を超える確率を照会できます。

海上判断では、海況を過小評価するコストが大きくなりがちです。危険な条件の確率が中程度でも、航路、作業時間帯、安全余裕を変える理由になります。

このプロダクトは有義波高などの波浪変数と、しきい値ごとの確率レイヤーに焦点を当てます。prob >3のようなカタログのinfo値はAPIセレクタの一部なので、正確に保持します。

GribStreamでは、海上リスクが必要で、全球大気条件だけでは足りない場合に、gefswaveprobをGEFS Atmosと組み合わせて使えます。

主な特徴:

GEFS Waveアンサンブルから派生した確率的な波浪プロダクトです。
有義波高などが運用しきい値を超える確率を照会できます。
海上リスクに確率が必要な場合、決定論的な波浪予報を補完します。

解像度: GEFS Waveソースが定義する全球波浪格子。

更新頻度と時間範囲: ソースが公開する場合、中期の予報範囲を持つ全球GEFS Waveサイクル。

主な用途: 海上ルーティング、洋上運用、港湾計画、マリンスポーツ、海上保険、運用しきい値を超える波浪確率に基づくアラート。
