気候値アトラス(hysk)

概要

私がよく使うデータの気候値(created at 2015-07-27, under const.). 自分自身がデータ・画像の所在を忘れるので,記録. 画像のサムネイルとそれを作成したスクリプト名,作成日.

手元にある既存データを使ってるので,必ずしも最新期間まで更新されていないので要注意.

雪氷要素

SST, SIC, snow cover などなど.順次追加予定.

SST, SIC, snow cover (NH)

最新の状況が見たい場合: See MASIE (NSIDC)

  • SST: OI SST, 1982-2011, 0.25 degree. Unit = Kelvin; See also 陸域・海洋データ(hysk) > OI SST
  • SIC: OI SST, 1982-2011, 0.25 degree. Unit = percent (%)
  • snow cover: SSM/I, 1988 - 2002, 0.333 degree. weekly. Use mid week of month. Unit = percent (%). Too old. You should UPDATE to the latest dataset in the near future... (checked: 2015-07-27)
  • script_name = ~/ocean/sst/OISST_daily-0.25deg/climate/gmt/203_monthly_clim_w_SC_NH.gmt
    • 以下,作図(GMT使用) に関する技術的情報.
    • GMT による作図.SIC, snow cover は,grdview を使用. 非表示としたい数値範囲を強制的に NaN 指定し,color palette の N を transparent に指定 ("-") することで, 2種の異なるデータの塗りつぶしが可能となった.
    • sea ice (海)と積雪(陸上)という,データが空間的に重複しないデータだからこそ出来たこと. 「海氷上の積雪」という情報が加わるとお手上げ.
    • See also Linux Tips > GMT サンプル > マスクアウト(3)
  • Latest sea ice & land snow: See NH land snow & sea ice extent (IMS product ver.3; U.S. NIC & Naval Ice Center)

補助資料 Supplemental materials

私的に追加した,補助的な climate atlas. 一般的な Atlas ページには記載されてなさそうな要素のみ.

T & dT/dy (850-hPa, JRA55, 1981-2000 monthly mean)

  • JRA55 850-hPa temperature, 1981-2000 monthly mean
  • shade: dT/dy (K/(100 km)), contour: T (K; CI = 2K)
  • script: ~/JRA/climate/grads/502_clim_grad_T.sh (using GrADS)
  • CAUTION: DO NOT masked below ground
  • 一般的には,高緯度側ほど低温になるはずなので,dT/dy < 0 (青系).
  • ただし,一部地域・季節では南北温度傾度が逆転する
    • 寒侯期の北東シベリア,グリーンランド北部(地域的な気温極小域の高緯度側)
    • 暖侯期のアラスカ南部,アメリカ南西部〜メキシコ
    • 低緯度乾燥地域の南側(Saharaの南,アラビア半島の南)など
  • 春季から夏季にかけて,ユーラシア大陸上の傾圧帯が北上. 夏季には北極海沿岸(70N付近)に沿って分布. ここがいわゆる極前線帯なのだろう. 陸上積雪や海氷分布と重ねて表示すれば,これら傾圧帯が積雪・海氷の縁辺部に位置することがわかるだろう.
  • 水蒸気の南北傾度も作りたいな...梅雨前線がはっきり見えそうだ.気が向いたら.

測定局観測データ

気象庁webよりも 気象庁web 英語版ページの方が見つけやすい. こっちの方が作りがシンプルなので,私には使いやすい(checked 2016-02-26).
