(Master thesis / Masteroppgave, 2010)Forecasting severe weather events is of great importance, especially since it can have impact on life and society. Even though numerical weather prediction (NWP) models have had great improvements in the last decade, some ...
-
(Master thesis / Masteroppgave, 2010)Based on linear shallow water theory for a uniformly rotating, homogeneous ocean, the properties of freely propagating shelf waves are investigated, applying the rigid lid approximation. Applied to the Norwegian shelf, ...
-
(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, 2010)Forcing perturbations, which are optimal in producing atmospheric respons patterns resembling the Cold-Ocean-Warm-Land (COWL) flow regime over 4 days, have been calculated with the atmospheric Integrated Forecast ...

(Master thesis / Masteroppgave, 2010)In boundary layer modelling, the Monin-Obukhov theory is widely used to parmeterize the wind profiles and the momentum fluxes. During the IPY-THORPEX campaign at Andøya at 3. March 2008, a flight was made across an arctic ...
-
(Master thesis / Masteroppgave, 2010)We consider the relative importance of wind and currents in the determination of optimal routes, commonly referred to as weather routing, for sailboats. Weather routing for sailboats is the process of finding the fastest ...
-
(Master thesis / Masteroppgave, 2011)I denne oppgaven har vi studert lavfrekvent variabiliteten i havet gjennom det 20-århundret. I tillegg til observasjoner har vi brukt data fra fire klimamodeller; CCSM3, Gfdl-CM2.0, BCM2.0 og HadCM3, som er kjørt med ...

(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, 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, 2011)Regional climate modeling has become an important tool for downscaling global climate models (GCMs), to assess high impact regional climate pro-jections. Southern Africa is one of the most exposed regions to the effects ...
-
(Master thesis / Masteroppgave, 2011)Relative dispersion is a widely used measure to characterize mixing properties of atmospheric passive tracers. Numerical models allow for a large number of particles. In this thesis, the Lagrangian transport model FLEXPART ...
-
(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, 2011)IPCC results indicate that the main bulk of uncertainties on global warming is within aerosol-cloud interactions. Based on observations this thesis aims to measure how anthropogenic aerosol from mid-latitudes increase ...
-
(Master thesis / Masteroppgave, 2011)The polar low in the Norwegian Sea on March 16-17 2008 has been studied using both weather analysis and the numerical weather prediction (NWP) model weather research and forecasting (WRF). This particular polar low was ...
-
(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, 2012)Wildfires are a source of major perturbations in the earth-atmosphere system. Between 1997 and 2008, an area of roughly 4 · 106 km2 has been burned each year. Among other species, wildfire aerosols consist of black carbon ...
