WRF(Weather Research and Forecasting Model)とその前処理であるWPS関連。

ARWとNMM

Geogridに関する資料を読んでいる。
http://www2.mmm.ucar.edu/wrf/users/tutorial/200907/Basic/WPS-general.pdf

p14とp15に2つのドメインでの定義図がある。

  • Geogrid: Defining NMM Domains

ARWとNMMについては検索して以下を見つけた。

The Weather Research and Forecasting (WRF) model contains two dynamic cores: the Non-hydrostatic Mesoscale Model (NMM – Janjic 2003) core (developed at the National Centers for Environmental Prediction (NCEP) and the Advanced Research WRF (ARW – Skamarock et al. 2005) core,

dynamic coreが2種類あり、使っている方のcoreに関してgrid定義をすればいい。
