16. Air-sea exchange of O2 and CO2 : Processes controlling the transfer efficiency
Sammanfattning : World oceans cover more than 70% of the earth surface and constitutes a major sink of atmospheric CO2. Two of the most important gases in the marine carbon cycling are O2 and CO2 and hence accurate descriptions of the air-sea gas exchange of these gases are crucial. LÄS MER
17. A Variational data assimilation scheme and its use of meteorological observations
Sammanfattning : Meteorological data assimilation is the process by which a model simulation of the atmosphere is corrected by observations. In operational weather forecasting, this is done in near real-time, to provide accurate initial conditions for numerical forecasts. The accuracy of the forecasts depends crucially on the accuracy of the data assimilation. LÄS MER

19. Atmospheric circulation regimes and climate change
Sammanfattning : The Earth's atmosphere is expected to warm in response to increasing atmospheric concentrations of greenhouse gases (GHG). The response of the Earth's complex and chaotic climate system to the GHG emissions is, however, difficult to assess. In this thesis, two issues of importance for the assessment of this response are studied. LÄS MER
20. Computational fluid dynamics for dispersion calculation in urban surroundings
Sammanfattning : Increased knowledge on dispersion processes in urban environment will enhance the ability in the society to handle events where releases of toxic substances can occur. Also, the ability to increase preparedness at locations where such events potentially can emerge. LÄS MER
