(Master thesis / Masteroppgave, 2015)We assess how reliable the Eddy-Covariance (EC) method is in estimating surface fluxes under the difficult conditions that occur in the high Arctic. Emphasis is placed on stable stratification and the breakdown of EC ...

Autonomous monitoring of the Nordic Seas by hooded seals - experiences gained during the International Polar YearRestricted Access (Master thesis / Masteroppgave, 2012)Oseanografiske data ble samlet inn ved hjelp av 20 klappmyss i de Nordiske havene i 2007 og 2008, som en del av IPY-prosjektet MEOP. 6112 vertikale profiler av temperatur og konduktivitet ble samlet inn. Selene dykker dypt, ...

Betydning av meteorologiske målinger med rutefly (AMDAR) for kvaliteten av numeriske værprognoser i Norge.Restricted Access (Master thesis / Masteroppgave, 2008)Initial condition will improve the weather forecast and that is the subject in this master thesis. Will weather observations from aircrat improve the weather prognoses in Norway. Forecast have been made for observings ...
-
(Master thesis / Masteroppgave, 2011)The Arctic Ocean is supplied with water from the Atlantic and Pacific through the Nordic Seas and the Bering Strait. Changes in temperature, salinity and density are seen in the Amundsen, Makarov and Beaufort Basins. The ...
-
(Master thesis / Masteroppgave, 2018)Previous studies showed the importance to have information about the vertical distribution of precipitation to simulate snow and related cyclone development correctly in regional, mesoscale models. During Christmas 2016, ...
-
(Doctoral thesis / Doktoravhandling, 2013)Bølgemekanismer i havet slik som ”Stokes drift” bidrar til å systematisk forflytte store mengder vannpartikler i en bestemt retning over store avstander. Stokes drift har blitt studert grundig for overflatebølger for ...
-
(Master thesis / Masteroppgave, 2011)Extreme mesoscale weather in the Arctic region often forms in the vicinity of the ice edge. A polar low was observed in the region between Svalbard and the ice cap, 8. january 2010. This was the first polar low to have ...
-
(Master thesis / Masteroppgave, 2009)Ved å bruke en invers metode kan høydeprofilen av svoveldioksid (SO2) utslippene fra et vulkanutbrudd estimeres. Metoden bruker satellitt observerte SO2 kolonneverdier (AIRS, OMI) og en partikkel dispersjons modell (FLEXPART) ...

(Master thesis / Masteroppgave, 2011)Den turbulente dynamikken i det øvre havet er et mye omtalt tema av forskere. Tidligere studier har vist seg og støtte to hovedteorier; overflate kvasigeotrofisk teori og to dimensional teori. I denne oppgaven har vi brukt ...
-
(Master thesis / Masteroppgave, 2011)En samling av nedleggelse ordninger for Eddy diffusivities κ, passende for isopycnal diffusjon (Redi 1982) og omrøring (Gent-McWilliams 1990), er testet og sammenlignet med utgang fra høy oppløsning regional havmodell. ...
-
(Master thesis / Masteroppgave, 2010)High resolution forecast models have the potential to produce more detailed forecasts of, for example precipitation, than comparable models with a coarser resolution. This is because high resolution forecast models, amongst ...
-
(Master thesis / Masteroppgave, 2008)This thesis concerns the equilibrium climate response to an anthropogenic change in aerosols since pre-industrial times compared to a 63 % increased CO2 level in the atmospheric GCM CAM-Oslo coupled to a slab ocean model. ...
-
(Master thesis / Masteroppgave, 2012)Anthropogenicgreenhouse gases have become widely accepted as the primary cause of global warming. With increasing emissions rates, warming is set to continue and baring any drastic change in mitigation policies, the rate ...
-
(Master thesis / Masteroppgave, 2014)We consider results from from a one year simulation in the Oslofjord area, produced by an 800- and 300- meter versions of the ROMS model. The two versions differ only in resolution and grid orientation. Our objective is ...
-
(Master thesis / Masteroppgave, 2010)Forskning over de siste ti årene har etablert at dagens bakgrunnskonsentrasjon av bakkenær ozon er høy nok til å ha skadelig effekt på vegetasjon. Disse effektene inkluderer reduksjon i biomasseproduksjon, trevekst og ...
-
(Master thesis / Masteroppgave, 2020)Helicopters are sometimes hit by lightning when flying offshore along the coast of Norway. Often, the helicopter’s presence is what triggers the lightning strike, and this phenomenon is called Helicopter Triggered Lightning ...

(Master thesis / Masteroppgave, 2009)A short range, limited area ensemble prediction system, LAMEPS, is currently in operational use at the Norwegian Meteorological Institute. It employs 3D-Var for 6 hourly data assimilation cycling for analysis of the control ...
