GraphCast Global Forecast System (GFS GraphCast)

GribStreamコード: graphcast

ステータス: GribStreamではgraphcastを実験的な履歴アーカイブとして提供しています。GribStreamでのGraphCastGFSカバー範囲は2026-05-05 00:00 UTCのモデル実行までです。NOAA EAGLE registryはAIGFSとAIGEFSをEAGLE SOLO/Ensembleファミリーの運用後継と説明しています。NOAAの現在のAIベース全球予報にはAIGFSまたはAIGEFSを使ってください。

概要

GraphCast Global Forecast Systemは、Google DeepMindの機械学習モデルGraphCastを基にNOAA/NCEPが構築した実験的な全球予報です。GribStreamでは、比較、研究、過去検証向けの履歴アーカイブとして保持しています。

中核モデルはメッセージ伝播を使うグラフニューラルネットワークで、encoder-processor-decoder構成です。ERA5で事前学習され、NOAA公開版ではGDASの2つの解析状態、つまり現在時刻と6 h前の状態を入力に使います。

提供される構成は13の気圧面に焦点を当て、気温、風成分、ジオポテンシャル高度、比湿、鉛直速度、標準的な地表付近変数を含みます。

graphcastの履歴カバー範囲は2026-05-05 00:00 UTCのモデル実行までです。現在のAIベース全球サイクルには、NOAAのAIGFS/AIGEFS、またはECMWFのAIFSを使ってください。

GraphCastはGDAS初期条件を通じてGFSと関係し、AIGFSやAIFSのような他のAIベース全球モデルとも比較できます。物理ベースの数値予報を置き換えるものではなく、履歴検証、過去検証、リスク評価で併用するデータセットです。
