Regional atmospheric models have matured in the past few years. They now find broad applications that range from process studies, reconstruction of recent and paleoclimates, simulation of pathways and deposition of anthropogenic matter, construction of plausible scenarios of future climate change, and regional weather analysis. The initial major(More)
An analysis of the storm climate of the Northeast Atlantic and the North Sea as simulated by a regional climate model for the past 44 years is presented. The model simulates the period 1958-2001 driven by the National Center for Environmental Prediction’s (NCEP’s) weather re-analysis. Comparison with observations shows that the model is capable of(More)
The paper describes the initial efforts in a project whose objective is to obtain a 40-year hindcast of wind, sea level and wave climatology for European waters. The 40-year global atmospheric re-analysis carried out by the National Centre for Environmental Prediction, Washington, USA (NCEP) and the National Centre for Atmospheric Research, Boulder,(More)
Climatic fluctuations on a decadal timescale in the North Atlantic in a global ocean general circulation model were considered. The analysis was carried out for the 3800-year stochastic forcing simulation of Mikolajewicz and Maier-Reimer in which the Hamburg LargeScale Geostrophic ocean model was driven by monthly climatologies of wind stress, air(More)
The planing of sustainable development and of economic activities in the marine environment requires long term information about the prevailing environmental conditions. For the design of marine and coastal protection structures detailed knowledge on local wave conditions is an essential prerequisite. To estimate the risk which emerges from local wave(More)
The influence of quasi-realistic high-frequency wind variability for the probability distribution of surface waves and for the skill of the predictions with the wave model WAM is investigated. So far, the sensitivity of the surface wave field to high-frequency wind variability has been demonstrated only for idealized wave conditions or particular events(More)
An alternative approach for the parameterization of the air-sea momentum flux in the marine surface boundary layer was implemented into a regional coupled atmosphere-wave model. The sensitivity of the atmospheric circulation to this new parameterization was assessed and compared to two different approaches using Monte Carlo simulations. Two approaches(More)
