1. Solitary waves and enhanced incoherent scatter ion lines
Sammanfattning : This thesis addresses solitary waves and their significance for auroral particle acceleration, coronal heating and incoherent scatter radar spectra. Solitary waves are formed due to a balance of nonlinear and dispersive effects. LÄS MER
2. Freshwater, density gradients and biological processes in cold, brackish seas : aspects of the biogeophysical fluid dynamics characterising the Baltic Sea
Sammanfattning : The dominant component in the ocean water is freshwater. In this thesis its mixing and the freshwater-induced dynamics are discussed, with cold, brackish basins such as the Baltic Sea especially in mind. A mathematical framework is derived to allow for a consistent way of adding freshwater effects to the governing equations. LÄS MER
3. Electron-scale physics in space plasma : Thin boundaries and magnetic reconnection
Sammanfattning : Most of the observable Universe consists of plasma, a kind of ionized gas that interacts with electric and magnetic fields. Large volumes of space are filled with relatively uniform plasmas that convect with the magnetic field. LÄS MER
4. Water and heat exchange processes over the Baltic sea
Sammanfattning : Before we can reach understanding of the global climate and predict climate changes accurately we must be able to understand water and energy budgets. The atmosphere-water exchange processes are of great importance. LÄS MER
5. Some Physical and Environmental Aspects of Shallow Ice Covered Lakes : Emphasis on Lake Vendyurskoe, Karelia, Russia
Sammanfattning : The ice cover presence on the surface of a lake insulates the water body from the atmosphere. This prevents or reduces the influence of processes which depend on the exchange between the atmosphere and the water surface. LÄS MER
