Opis
WRF (engl. Weather Research and Forecasting Model) je mezoskalni meteorološki model namijenjen znanstvenom istraživanju i operativnoj prognozi koji u sebi sadrži razne metode parametrizacije fizikalnih procesa poput: kemijskih procesa u atmosferi, hidrologije, površinske razmjene, požara ili uragana. Verzija koja je podržana na supperračunalu Supek je verzija s dinamičkom jezgrom ARW, koja se tipično koristi u prognostičke svrhe.

Dokumentacija
Primjer korištenja
Ispod se nalaze skripte osnovnog primjera korištenja na uraganu Matthew koje odgovaraju tipičnom workflowu za pripremu i izvođenje simulacije.
Ulazni podaci su:
- namelist.wps - ulazna datoteka dijela WPS
- namelist.input - ulazna datoteka dijela WRF
PBS skripte koje treba izvršiti navedenim redom su:
- wps.sh - preprocessing dio WPS
- wrf-real.sh - preprocessing dio WRF
- wrf.sh - simulacija modelom WRF
