A NAWDEX case study: Water vapor transport in atmospheric rivers and quantifying hand over of moisture between extratropical cyclones
(Master thesis, 2020-10-31)Meridional water vapor transport occurs predominantly within the warm sector of extratropical cyclones. The warm sector is seperated by the cyclone's warm front ahead, and the cold front behind. In this region the warm ... -
Air-Sea Interactions during Cold Air Outbreaks in a coupled Mixed Layer Model
(Master thesis, 2019-06-19)Cold air outbreaks play a crucial role in the air-sea heat exchange in high latitudes. To explore the sensitivity to ocean coupling, the role of latent heating and the sensitivity to sea ice distributions in cold air ... -
Airborne Field Measurements and Model Simulations of Boundary Layer Properties over the Iceland Sea
(Master thesis, 2019-06-28)The spatial and temporal distributions of a cold air outbreak (CAO) event over the Iceland- and southern Greenland Seas have been investigated during the IcelandGreenland Seas project (IGP) in February and March 2018. This ... -

Anthropogenic Carbon in the Nordic seas and Arctic Ocean, 1994 to 2007
(Master thesis, 2019-06-28)The increase of anthropogenic CO2 between 1994 and 2007 is quantified in the Nordic seas and Arctic Ocean with the extended multiple linear regression method (eMLR(C*)). To be able to map the increase in anthropogenic CO2 ... -
Atlantic Multidecadal Variability (AMV) in the Norwegian Earth System model
(Master thesis, 2020-06-26)The causes of low-frequency sea surface temperature (SST) variations in the Atlantic, known as Atlantic Multidecadal Variability (AMV), are debated. AMV has climatic impacts on for instance hurricane activity and Sahel ... -
Bidirectional DC-DC Converter For Charging Batteries of Electric Vehicles
(Master thesis, 2021-06-01)The popularity of electric vehicles has seen significant growth in the latest years. More electric vehicles are connected to the grid, and the load is increased consequently. The electric vehicle battery can be employed ... -
Bidirectional DC-DC Converter for Supercapacitor as DC-bus Stabilization Element
(Master thesis, 2021-06-01)The demand for renewable energy from wind and solar is increasing. These energy sources are intermittent and unpredictable to a degree and require a stable but fast responding DCgrid. This is achieved by extending the ... -
