Stratified flow past a sphere at moderate Reynolds numbers
A numerical study of stably stratified flows past spheres at Reynolds numbers Re = 200 and Re = 300 is reported. In these flow regimes, a neutrally stratified laminar flow...- publication PDF

Evolution of summer Arctic sea ice albedo in CCSM4 simulations: Episodic...
The albedo of Arctic sea ice is calculated from summertime output of twentieth century Community Climate System Model v.4 (CCSM4) simulations. This is compared with an empirical...- publication PDF

Urbanization impacts on evapotranspiration across various spatio-temporal scales
Urbanization has been shown to locally increase the nighttime temperatures creating urban heat islands, which partly arise due to evapotranspiration (ET) reduction. It is...- publication PDF

Trends in sunspots and North Atlantic sea level pressure
We analyze the periods 1878-1944 and 1944-2008. The quasi-stationary wave in the North Atlantic region was stronger and the baroclinity steeper in 1878-1944 than in 1944-2008....- publication PDF
