(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 / Hovedoppgave, 1972)In this work we have examined the baroclinic instability in a linear two layer model, where the perturbations are presume to depend the latitude. From the linear equations we have computed the growthrates and speeds of ...
-
(Master thesis / Masteroppgave, 2017)In this thesis, the large-scale thermohaline circulation in the Late Permian was studied. A steady state circulation was obtained by running MITgcm with a 2 times 2 degrees spherical-polar grid, and solving the nonlinear ...

-
(Master thesis / Masteroppgave, 2015)Observational data from 61 moorings was used to decompose vertical velocity fields into its modal components using two different approaches, one assuming a flat bottom ocean and one assuming an ocean with rough topography. ...
-
(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, 2009)
-
(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, 2018)We know that lichen cover in polar and high altitude regions may change due to grazing or climate change. Some previous studies have found that removal of lichen reduces the albedo and potentially changes the temperature, ...
-
(Master thesis / Masteroppgave, 2016)Climate change has increased extreme weather events over the planet. The most robust changes in East Africa (EA) are for daily temperature and precipitation, where high-impact extreme values have become more common. The ...
-
(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, 2018)Flux towers provide important climatic information about surface exchange processes in the land-atmosphere system. At the Finse flux tower in alpine Norway, the inhomogeneous surface and hilly terrain influence the quality ...
-
(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, 2018)Precipitation patterns and rates change with global warming. These changes can be separately evaluated in fast and slow responses, the combination of the two are called apparent responses. The fast precipitation responses ...
-
(Master thesis / Masteroppgave, 2010)Seven experiments are conducted on a coupled ice-ocean model in order to gain insight in the sensitivity of the modeled Arctic sea-ice extent and thickness to crucial changes in the parametrization of the models albedo ...
-
(Master thesis / Masteroppgave, 2009)Clouds in the Arctic differ from clouds elsewhere in that they have a net warming effect at the surface. This happens because the longwave (LW) radiation dominates the radiation regime due to large solar zenith angles ...
-
Smoke detection in Europe from wildfires in North America and its impact on the surface temperature (Master thesis / Masteroppgave, 2014)In the summer of 2013, Europe got affected by smoke from wildfires in North America. A haze was covering the sky, attenuating the incident solar radiation, at many places in Europe. Especially during two periods, high ...
-
(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, 2017)Two cases of severe thunderstorms that impacted the Oslo area have been investigated. The thunderstorms occurred during the summer of 2014, an extraordinary summer with record high temperatures, number of lightning strikes ...
-
(Master thesis / Masteroppgave, 2015)The timescales of transport from the surface to the tropical tropopause layer (TTL) was studied using the Lagrangian transport model Flexpart. The model was driven by the ERA-Interim reanalysis from the European Center for ...
