Ideal and Real Atmospheric Boundary Layers is based on the notion that classical Boundary Layer Meteorology books largely focus on ideal surface conditions, while the current actual problems often address situations in which those do not prevail. Ideal and Real Atmospheric Boundary Layers starts by covering the basic physical principles used in atmospheric boundary layer meteorology, including atmospheric turbulence, observing and modeling atmospheric boundary layers, neutral, convective and stable boundary layers over different types of land surfaces. The second part of the book describes the applications of these principles as well as their limitations in real-world circumstances. The book will be of interest to researchers and students in atmospheric science, climate science, and meteorology.
