(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 / Hovedoppgave, 2005)This thesis looks into features of the volume flux in the narrow Drøbak strait, and water level changes in the inner Oslofjord. Earlier measurements suggest that the volum flux in the east course of the strait, calculated ...
-
(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. ...

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, 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, 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, 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, 2009)In this thesis, transport pathways, temporal trends and seasonality of persistent organic pollutants (POPs) in the Arctic are examined. These pollutants, which can be transported over long distances, constitute a great ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2009)
-
(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 ...
-
(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, 2009)
-
(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, 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)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, 2010)
-
(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 ...
