Environmental Turbulence

Environmental Turbulence explains how to understand environmental and geophysical turbulence, both at a theoretical level and in engineering applications. Turbulence in environmental media is strongly modulated by buoyancy forces at all scales and by rotation at the largest scales, in contrast to canonical turbulent flows. It is rarely steady, which can give rise to non-equilibrium effects, and the domains such as wind farms or cities are often quite complex, leading to more intricate dynamics than in classic wall-bounded or free shear flows. This added complexity along two axes is tackled in this book. First, the effects of these new features on the fundamental flow dynamics are introduced in relatively simple domains. That is, how the turbulence statistics and structure are modified by the stabilizing or destabilizing effects of buoyancy and rotation is surveyed. Scalar transport is also an important topic that is described in detail. Flow in more complex domains is then described, focusing on vegetated and urban canopies, wind farms, air-sea interfaces, the upper ocean and clouds.
