Wind Stress in the Coastal Zone: Observations from a Buoy in Southwestern Norway

Atmosphere, 2019
Several studies have focused on the investigation of the wind stress in open ocean conditions where coastal processes were negligible. However, the direction and magnitude of the wind stress vector in coastal areas are still not fully known due to the ...

An offshore wind union? Diversity and convergence in European offshore wind governance [PDF]

Climate Policy, 2015
Offshore wind megaprojects in European waters have significant carbon abatement potential and increasing their number is a policy goal for several European maritime nations. But experience has shown that governance of large-scale, commercial offshore wind development is not straightforward.

Implementation of a sigma coordinate system in PALM-Sigma v1.0 (based on PALM v21.10) for LES study of the marine atmospheric boundary layer [PDF]

Geoscientific Model Development
In large-eddy simulation studies of the marine atmospheric boundary layer, wind-wave interactions are often oversimplified using wall-stress models parameterized by roughness length, overlooking the complex coupling dynamics, especially under wind-wave ...
