21. Evasion of CO₂ from streams : quantifying a carbon component of the aquatic conduit in the boreal landscape
Sammanfattning : Lateral export of carbon (C) from soils to running waters is a persistent pathway for C with terrestrial origin. This "aquatic conduit" might be especially important in boreal regions where a significant part of the global C stock is stored in the soil. LÄS MER
22. Transport and chemical processing of trace gases in deep convective clouds
Sammanfattning : Deep convective clouds can efficiently transport trace gases from the planetary boundary layer to the upper troposphere. Once there, some gases will contribute to new particle formation and growth, eventually producing aerosols that are large enough to influence cloud properties, the radiative budget of the Earth, and climate.

23. On the interaction between ice sheets and the large-scale atmospheric circulation over the last glacial cycle
Sammanfattning : The last glacial cycle (c. 115-12 kyr BP) was the most recent in a series of recurring glaciations of the subpolar continents. Massive ice sheets evolved in Eurasia and North America, which, at their maximum, were of continental scale and together lowered the global sea-level by approximately 100 m. LÄS MER
24. On atmospheric low frequency variability, teleconnections and link to jet variability
Sammanfattning : The atmosphere is a complex system with an infinite number of independent variables. The best approximations of the atmosphere are made using numerical models. The use of such models provides an invaluable tool for studying the atmospheric system. LÄS MER
25. Impact of surface gravity waves on air-sea fluxes and upper-ocean mixing
Sammanfattning : Surface gravity waves play a vital role in the air-sea interaction. They can alter the turbulence ofthe bottom atmospheric layer as well as the upper-ocean layer. Accordingly, they can affect themomentum flux, heat fluxes, as well as the upper-ocean mixing. In most numerical models, waveinfluences are not considered or not fully considered. LÄS MER
