GribStream

Climate Forecast System (CFS Isentropic)

GribStreamコード: cfsipvf

概要

CFS Isentropicは、一定の温位の面に沿ったClimate Forecast Systemフィールドを提供します。標準的な気圧面解析を補い、気塊輸送や上空力学を追いやすくします。

cfsipvfデータセットには、渦位、流線関数、気温減率などのフィールドが含まれます。これらはジェット気流、トラフ、前線、安定度、対流圏と下部成層圏のつながりを診断する助けになります。

GribStreamでは、GRIBファイル全体を処理せずに、長い予報範囲の力学的な背景場を取得したい用途に向いています。航空計画、上空診断、研究用途、CFS Pressureとの比較で使えます。

より一般的な大気変数にはCFS Pressureを、地表面やエネルギー収支の文脈にはCFS Radiative Fluxesを使ってください。
