1. Experimental studies of ice particle formation with tropospheric relevance
Sammanfattning : In their fourth assessment report, the Intergovernmental Panel on Climate Change points out the influence of particles suspended in air, known as an aerosol, as the main uncertainty in the understanding of the climate system. Aerosols affect climate in a number of ways. LÄS MER
2. Modeling aerosol-cloud interactions in the Arctic
Sammanfattning : Clouds have a large impact on Earth’s energy balance, especially in the Arctic. Through their warming or cooling effect on the surface, clouds can play a critical role in the onset of melting and freezing of Arctic sea ice, which itself has a large effect on energy and moisture fluxes between the ocean and the atmosphere.

3. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

4. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis
Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER
5. Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation
Sammanfattning : Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the energy balance of the planet. LÄS MER
