met.no: Status and Plans Helge Tangen, met.no – Tromsø office Arctic ROOS meeting, Luleå, December 18-19, 2007
Status; models • HIRLAM, ECMWF, UM4 • Atmosphere, … • WAM • Waves • Ice forecast 20 km, 2 km to be launched soon
Nordlys?, 14 april 1987: • ..fiskerne kan så å si telle isflak ned til 30 meters lengde.. • ..informasjonen kan være om bord i fiskefartøyenebare minutter etter at satellittinformasjonen er mottatt.. • På kartet er det lett å se hvor isen er tynn og hvor den er tykkere..
Wind speed & direction Resolution(km) – 20x20,10x10,4x4, (1x1) IPY-THORPEX campaign: 4 km for major parts of Barents Sea
Current Speed vectors Resolution 4 km
Drift modelling Oil spill Objects/peopler
Observations • Radio soundings Jan Mayen, Bjørnøya, Ny-Ålesund (with Max Planck) • Synoptic: Jan Mayen, Bjørnøya, Hopen, Longyearbyen, several AWS in Svalbard • Ice state and thickness Hopen, ice state Bjørnøya
Observations (2) • Synops along coast of Northern Norway • Satellite images from several polar orbiting missions • OSI SAF: Ice parameters and SST
Forecasting in the Arctic at met.no • Regular daily foreasts for large sea areas • Weather, wind, visibility, waves, iceing • Polar Low monitoring and forecasting • Aviation forecasting
Spesialvarsel for havområder Utstedt tirsdag 13.09.2005 kl. 10 UTC. Sterk kuling ventes i følgende områder: E4, F3, F4. Synoptisk situasjon kl 06 UTC: Lavtrykksenter 983 hPa i posisjon 79 nord 29 øst beveger seg sakte vestover og dyper seg langsomt . Lavtrykksenter 975 hPa i posisjon 63 nord 17 vest beveger seg østover med hastighet 25 knop og fylles langsomt. Værvarsel som gjelder for de neste 24 timene: A1, B1, C1:Nordvestlig frisk bris. Stort sett oppholdsvær og god sikt. A2, A3, B2, B3, C2, C3:Nordvestlig frisk bris til liten kuling. Spredte sludd eller snøbyger. Dårlig sikt i nedbør. A4, A5, A6:Skiftende bris. Spredte snøbyger. Dårlig sikt i nedbør. B4:Nordvestlig bris. Spredte snøbyger. Dårlig sikt i nedbør. Osv…

Dissemination of info • http://wms.met.no/moncoze (met.no model output combined with data from NERSC (TOPAZ, ASAR,MERIS) • http://senorge.no (shows wms layers from distributed sources (met.no, NVE) • http://wms.met.no/hydronord , focussed on the Barents Sea. met.no, NERSC, IMR, NIVA have intension to develop moncoze-client in a new project ”MONBASE” (Monitoring the Barents Sea Environment) • Partners in AROOS could work together on web-dissemination (wms, wfs, wcs)

Projects • iAOOS-Integrated Arctic Ocean Observing System • MyOcean: Arctic Monitoring and Forecasting Center (MFC) development in Norway (NERSC, met.no, IMR), drifted at met.no. Also Sea Ice Thematic Assembly Center (TAC) managed by met.no. (According to proposal) • Polar View: High resolution ice charting & management MyOcean • Hindcast project (StatoilHydro) for better climatology in the Barents Sea
Icebergs • Iceberg service: Contract to be signed with StatoilHydro on developing service in the Barents Sea. Will be included in official forecasting service.
