(Master thesis / Masteroppgave, 2015)The advent of satelitte observations revolutionalized Oceanography, and it has unveiled a turbulent ocean circulation dominated by mesoscale eddies (10-100km). Eddies represent an important aspect of the flow, and understanding ...
-
(Master thesis / Masteroppgave, 2009)Svalbard, ei øygruppe i Arktis, vert påverka både av langtransportert og lokal forureining. I denne oppgåva har konsentrasjonar av elementært karbon (EC) i snøen og effekten det har på albedo blitt undersøkt. Eit overslag ...
-
(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, 2019)Heavy rain events in the Arctic archipelago Svalbard can have a high impact on nature and settlements, and are predicted to become more frequent and intense in the coming decades. This thesis work focuses on heavy rain ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2013)Arktis har vært, og er fortsatt, et utfordrende område for numeriske modeller for studier av fenomener knyttet til skyer. Mye av dette skyldes at skyer ikke blir simulert godt nok. Spesielt det å simulere underkjølt skyvann, ...
-
(Master thesis / Masteroppgave, 2009)We decided to take a fresh new look at the historical hydrographic data from the Environmental Working Group-atlas (EWG) in light of the recent dramatic changes, first and foremost to shed light on the cause of the large ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2009)The heat capacity of the global ocean is very large compared to the rest of the spheres in the climate system of the Earth. It is therefore reasonable to assume that ocean heat uptake or release would manifest itself in ...
-
(Master thesis / Masteroppgave, 2014)The emission of ozone precursors as CO, and NOx has increased over the last decades, this report looks at how this increase potentially could affect the concentration of tropospheric ozone over India. It gives a short ...
-
(Master thesis / Masteroppgave, 2009)Aerosols have in recent years been given increased attention due to their effects on climate and health. Drastic reductions in sulphur emissions in Europe during the last two decades have led to a larger relative importance ...
-
(Master thesis / Masteroppgave, 2018)Air pollution from traffic is a major health problem in urban areas, and there is a great interest in modeling and measuring the dispersion of pollutants from near- ground sources. Due to the complex nature of the motions ...
-
(Master thesis / Masteroppgave, 2010)The growth of the international ship trade has raised the great concern about the impact of the ship emitted pollutants to the clouds and climate, air quality est. Apart from emitting large extents of sulphur dioxide which ...
-
(Master thesis / Masteroppgave, 2009)This thesis presents results from an AGCM sensitivity study in which the response in the Northern Hemisphere storm tracks to an imposed SST anomaly is investigated. The study was motivated by observational studies cited ...
