Instability in Geophysical Flows (eBook, PDF)

• Format: PDF

Produktbeschreibung

Instabilities are present in all natural fluids from rivers to atmospheres. This book considers the physical processes that generate instability. Part I describes the normal mode instabilities most important in geophysical applications, including convection, shear instability and baroclinic instability. Classical analytical approaches are covered, while also emphasising numerical methods, mechanisms such as internal wave resonance, and simple `rules of thumb' that permit assessment of instability quickly and intuitively. Part II introduces the cutting edge: nonmodal instabilities, the relationship between instability and turbulence, self-organised criticality, and advanced numerical techniques. Featuring numerous exercises and projects, the book is ideal for advanced students and researchers wishing to understand flow instability and apply it to their own research. It can be used to teach courses in oceanography, atmospheric science, coastal engineering, applied mathematics and environmental science. Exercise solutions and MATLAB(R) examples are provided online. Also available as Open Access on Cambridge Core.

Autorenporträt

William D. Smyth was trained in theoretical physics and is now a professor of oceanography at Oregon State University. He has taught graduate-level courses in fluid mechanics, geophysical waves and instabilities, descriptive oceanography, dynamic meteorology and climate. His research interests focus on instability and turbulence in geophysical flows and on the broader study of complex phenomena. He has been a visiting scientist at the Liebnitz Institute for Baltic Sea Research in Germany. He has twice received the Pattulo Award for Excellence in Teaching, and has been honoured with the Kirby Liang Fellowship from Bangor University in Wales and a Distinguished Visitor Fellowship from Xiamen University in China.
