Beskrivning

Part of the excitement in boundary-layer meteorology is the challenge associated with turbulent flow - one of the unsolved problems in classical physics. An additional attraction of the filed is the rich diversity of topics and research methods that are collected under the umbrella-term of boundary-layer meteorology. The flavor of the challenges and the excitement associated with the study of the atmospheric boundary layer are captured in this textbook. Fundamental concepts and mathematics are presented prior to their use, physical interpretations of the terms in equations are given, sample data are shown, examples are solved, and exercises are included.The work should also be considered as a major reference and as a review of the literature, since it includes tables of parameterizatlons, procedures, filed experiments, useful constants, and graphs of various phenomena under a variety of conditions. It is assumed that the work will be used at the beginning graduate level for students with an undergraduate background in meteorology, but the author envisions, and has catered for, a heterogeneity in the background and experience of his readers.

'The book is an impressive work and will be of value to many students, researchers and operational meteorologists,' Journal of Fluid Mechanics, 224, 1991 '... the detailed excellent treatment of the broad field of boundary layer meteorology makes the book most valuable, not only to students, but to anyone interested in turbulence in the boundary layer.' J. Borkowski, Pageoph, 133:1, 1990 'In summary the book is highly recommended for graduate students of meteorology as well as air chemists and aerosol physicists wanting to interpret their measured data in terms of boundary layer phenomena.' Atmospheric Research 26, 1991 'Das Buch is allemal eine Investition wert und wird fur viele Jahre ein Standardwerk uber Grenzschichtmeteorologie bleiben. Einen 'Stull' sollte jeder (Grenzschicht-)Meteorologe besitzen.' Meteorologische Rundschau, 41:6 'Das Buch ist es wert, einem grossen Leserkreis zuganglich gemacht zu werden.Es spricht nicht nur den Studenten an, sondern jeden Meteorologen bis hin zum Experten aus ausgewahlten Gebieten der atmospharischen Grenzschicht. Der anschauliche and leichte Zugang zur Thematik ermoglicht aber auch vielen Wissenschaftlern benachbarten Disziplinen, die sich in ihrer Tatigkeit mit meteorologischen Prozessen der atmospharischen Grenzschicht auseindersetzen mussen, eine rasche und einfache Einarbeitung.' Zeitschrift fur Meterologie, 40, 1990
