1. Global Climatology and Regional Modeling of Coastal Low-Level Jets
Abstract : Localized coast-parallel wind-speed maxima at low altitude, known as coastal low-level jets (CLLJs) have important ramifications to the coastal climate and a number of human activities. This thesis documents the existence of the CLLJs around the globe including their mesoscale structure, dynamics and spatio-temporal variability. READ MORE

2. Mesoscale dynamics and boundary-layer structure in topographically forced low-level jets
Abstract : Two types of mesoscale wind-speed jet and their effects on boundary-layer structure were studied. The first is a coastal jet off the northern California coast, and the second is a katabatic jet over Vatnajökull, Iceland. READ MORE

3. Near surface atmospheric flow over high latitude glaciers
Abstract : In this thesis various descriptions of the near surface atmospheric flow over a high latitude glacier is used in an effort to increase our understanding of the basic flow dynamics there. Through their contribution to sea-level change, mountain glaciers play a significant role in Earth’s climate system. READ MORE

4. Mesoscale Processes over the Baltic Sea
Abstract : The objective of this thesis is to study mesoscale processes above the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction may have a large impact on the offshore conditions. It is only the last tens of years that offshore research has become more popular, and one reason for this is the increasing offshore wind energy, which poses the need for accurate estimates of wind speed and turbulence conditions in the marine environment.

5. Thermally driven wind modification in coastal areas and its influence on sound propagation with application to wind power
Abstract : The objective of the current study is to investigate the wind modifications in coastal areas and also to see the impact of atmospheric conditions on long-range sound propagation over sea. This is important when planning where to place wind turbines. READ MORE
