Starting as a vague idea to investigate the near surface wind climate over the North Sea, it evolved into its present form. I would like to thank a number of people who have contributed to the final result in many different ways:  \nFirstly my supervisor and colleague at ForWind Abha Sood who helped me to get started and planned additional activities such as workshops, summer schools and conferences, which helped me to extend my knowledge of atmospheric science. She has also greatly helped me in doing the research and writing the thesis by making critical suggestions and posing challenging questions.  \nI am also grateful to all colleagues at ForWind for nice working atmosphere and all the work and discussions we had together during the working time as well as in free time. Special thanks to Detlev Heinemann, the leader of our research group.  \nI was lucky to have my PhD position sponsored by European Union Marie-Curie Programme ModObs-Atmospheric modelling for wind energy, climate and environment applications: exploring added value from new observation technique (MRTN-CT-2005-019369) . It was a great opportunity to participate in the project. It gave me a lot of chances to widen my knowledge by supporting me to participate on the summer schools as well as it gave me opportunities to present my work at the conferences. I was also very fortunate to had chance to experience German culture.  \nI would also like to thank to the whole ModObs team, the students and supervisors for interesting meetings and exchanges of knowledge and experiences. Special thanks go to Anna Maria Sempreviva, the coordinator of the project.  \nI am also thankful to my thesis supervisor, Prof. Dr. Joachim Peinke for supporting me with the writing of the thesis and to the reviewers for investing their time to read the thesis and judge the quality of the work.  \nAbstract  \nThe knowledge of the near surface wind speed is important for numerous applications including wind energy. This thesis investigates the following aspects: i) the variability of the past near surface wind climate over the North-Western Europe and specifically over the North Sea and its relation to large scale circulation patterns; ii) possible future change of the near-surface wind climate over Europe and North Atlantic; and iii) improvement of Weather Research and Forecasting (WRF) model to simulate wind conditions in the lower part of the atmospheric boundary layer.  \nThe variability of wind speeds from different atmospheric reanalysis datasets in the past 50 years over the North-Western Europe and North Sea is studied. Wind speed patterns explaining majority of its variance were found and related to the variability of the large scale circulation patterns defined from Sea Level Pressure. Majority of wind speed variability can be described by three wind speed patterns or related circulation patterns. The wind speed and circulation patterns show coherent variability over the last decades. However, the extreme wind speeds are less well related to the circulation patterns.  \nWith a similar method as described above, the wind speed patterns and circulation patterns explaining the significant part of the wind speed trend have been found. The possible change of the circulation patterns from the results of the simulations of 16 IPCC models under A2 greenhouse gas scenario has been investigated.
