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, and neutral, convective, and stable boundary layers over different types of land surfaces. The second part of the book describes the applications and extension of these principles for real-world circumstances. The book will be of interest to researchers and students in atmospheric science, climate science, and meteorology.
- Covers state of current research into ideal and real boundary layers
- Includes methods and applications of the principles covered in the book
- Features highly visual content, including infographics to further exemplify principles and applications covered in the text
