This book is intended to give an introduction into the meteorological boundary conditions for
power generation from the wind onshore and offshore. It is to provide reliable meteorological
information for the planning and running of this important kind of renewable energy. This
includes the derivation of wind laws and wind profile descriptions especially those above the
logarithmic surface layer. Winds over complex terrain and nocturnal low-level jets are
considered as well. A special chapter is devoted to the efficiency of large wind parks and
their wakes.
