1. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions
Sammanfattning : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale. LÄS MER
2. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale
Sammanfattning : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. LÄS MER
3. Observing and Modeling Precipitation in the Tibetan Plateau region - from large-scale processes to convective storms
Sammanfattning : Climate change in mountain regions has far-reaching societal impacts such as increased risks for natural hazards and water scarcity that may affect billions of people in the downstream regions. Precipitation changes play a critical role in these impacts due to their effects on river runoff and flooding. LÄS MER
4. The Arctic Atmosphere : Interactions between clouds, boundary-layer turbulence and large-scale circulation
Sammanfattning : Arctic climate is changing fast, but weather forecast and climate models have serious deficiencies in representing the Arctic atmosphere, because of the special conditions that occur in this region. The cold ice surface and the advection of warm air aloft from the south result in a semi-continuous presence of a temperature inversion, known as the “Arctic inversion”, which is governed by interacting large-scale and local processes, such as surface fluxes and cloud formation.

5. Interactions between aerosols and large-scale circulation systems in the atmosphere
Sammanfattning : Anthropogenic aerosol emissions have increased during the last century. The higher atmospheric aerosol burden is believed to partly have masked the enhanced greenhouse gas warming during the same period. LÄS MER
