GFS mudel

GFS stands for the Global Forecast System. It is run by National Centers for Environmental Prediction (NCEP) which is a unit of NOAA (National Oceanic and Atmospheric Administration), NWS (National Weather Service), USA. The GFS is run four times per day (00 UTC, 06 UTC, 12 UTC, and 18 UTC) out to 384 hours. GFS is a global model so it covers all the Earth! Since January 2015 GFS has been producing forecasts with resolution of 27 km out to 240 hours.

NAM mudel

The North American Mesoscale (NAM) is a regional mesoscale model using enhanced terrain and improved parameterization of surface and precipitation processes. It is also run by NCEP, formerly its name was Eta, but in early 2005 it was renamed to NAM. Windguru uses 84 hour forecast data in 3 hour steps which covers Northern America with average resolution of 0.11 degrees (about 12 km). Updates four times per day. Much higher resolution than GFS should give more precise short term forecasts.

Since October 2011 NOAA/NCEP has added several high resolution subdomains to their NAM model. The first we use on windguru is the one that covers Hawaii in 3 km resolution. The subdomains run inside the main 12 km domain from 0 to 60 h, but at the moment we only show the first 36 hour forecast. The reason for this is that for 0-36h the output files are available in 1 hour steps, but 36-60h only in 3 hour steps, and it is not so easy to combine that in the current windguru forecast tables (at least for now, it will probably change in the future). Updates are 4 times per day.

WRF mudel

The Weather Research and Forecasting (WRF) Model is a next-generation mesocale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It is an evolutionary successor to the MM5 model. The effort to develop WRF has been a collaborative partnership, principally among the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (the National Centers for Environmental Prediction (NCEP) and the Forecast Systems Laboratory (FSL), the Air Force Weather Agency (AFWA), the Naval Research Laboratory, Oklahoma University, and the Federal Aviation Administration (FAA). Lisainfo WRF mudeli veebilehel.

We are running WRF model for most Europe and Mediterranean. Canary Islands, Madeira and part of Morocco's Atlantic coast are also covered by WRF with 9 km resolution. Another smaller WRF 9 km resolution domain covers Northern Red Sea with popular spots in Egypt, and also Israel, Lebannon and south of Cyprus. We also provide WRF 9 km forecasts for East Asia, this domain covers Japan, Korea, Taiwan and east China. Argentina, Chile and Uruguay are covered by WRF 12 km. Lähteandmed ja ääreväljad tulid GFS mudelist. Kui kõik läheb sujuvalt, uuendab WRF ennast 4 korda päevas ja loob ennustuse 78 tunniks ühetunnise sammuga. Ennustused sisaldavad tuule kiirust ja suunda, tuule puhanguid, temperatuuri, täielikku pilvkatet ning sademete hulka.

The highest resolution model we are running now is 3 km. Such a high resolution requires massive computing so the covered area can't be very large. WRF with 3 km covers Czech republic, forecasts are for next 48 hours and update 4 times per day. Another small 3 km domain covers one of the most famous areas for wind & kitesurfing in Europe - Tarifa / Strait of Gibraltar.

HRW model

The HRW (High Resolution Window) is WRF powered forecast model, it is run by American NOAA/NCEP same like GFS and NAM models described above. We use forecast data which cover Hawaiian islands with 5 km horizontal resolution and United States with 4 km resolution. Forecast length is 48 hours. Forecasts for Hawaii and US east update twice per day (model cycles 00 UTC and 12 UTC) and forecasts for US west update once per day (model cycle 06 UTC). Another smaller HRW 5 km domain covers part of Caribbean around Dominican republic and Puerto Rico and updates twice per day (cycles 06 UTC and 18 UTC).

As you can see on the maps below, the US east and US west domain overlap quite a lot, so if you view forecast for spot somewhere in the central US which is covered by both HRW domains you will always see the latest available model forecast - either from HRWe or HRWw depending on which one is the most up-to-date. So we can say that for central US the HRW model updates 3 times per day (00,06 and 12 UTC cycles)

Notice: Some or all HRW forecasts will not update if NOAA needs to run Hurricane models instead.

HRW forecasts are free to all users!
