The journal Boundary-Layer Meteorology was started in 1970 and has become a vehicle for the publication of research papers in its field. Dr R.E. Munn served as Editor-in-Chief until recently. The 25th anniversary volume, on which this book is based, was compiled from review and other articles solicited and selected as a Festschrift to honour Ted Munn’s achievement as editor of the journal over that time. Articles by leading contributors to the field include reviews of field studies (Askervein, HEXOS, Cabauw) and their impacts; numerical modelling (large-eddy simulation of the surface layer, frontal structures); analyses and critical discussions (of the von Karman constant, bulk aerodynamic formulations, air-sea interaction, vegetation canopies); and reviews or previews of progress in the understanding of the atmospheric boundary layer, turbulence simulation, Lagrangian descriptions of turbulent diffusion and remote sensing of the boundary layer. The collection provides a perspective on the state of the subject and where it is headed. It should prove useful for researchers and students of boundary-layer meteorology and related areas.
