This book offers a comprehensive review of our current understanding of the planetary
boundary layer, particularly the turbulent exchanges of momentum, heat
and passive scalars between the surface of the Earth and the atmosphere.
It presents and discusses the observations and the theory of the turbulent
boundary layer, both for homogeneous and more realistic
heterogeneous surface conditions, as well as the dispersion of tracers.
Lastly it addresses the main problems arising due to turbulence in weather, climate and
atmospheric composition numerical models.
Written for postgraduate and advanced undergraduate-level students and atmospheric
researchers, it is also of interest to anyone wanting to understand the findings and to
obtain an update on problems that have yet to be solved.
