What I’ve Learned about Turbulence and Clouds

Abstract: Clouds can be thought of as a large‐scale multiphase engineering flow: convection, turbulence, particles, phase changes, aggregation, and radiation transfer, all coupled together. Because this talk is at my home university, I’ll take a personal view: I’ve spent the last ~25 years learning about how turbulence influences the processes that take place in atmospheric clouds, and much of that research has been done in collaboration with mechanical engineering colleagues at institutions in Germany, India, Japan, and the USA. That interdisciplinary connection between atmospheric sciences and mechanical engineering has been valuable, and I think both communities have benefited from the interaction. We have a common language with the Navier‐Stokes equation, large‐eddy simulation, etc., but also have some different and complementary ways of approaching problems. I will discuss how turbulence influences one of the most practical problems in the atmospheric sciences, the formation of rain. My emphasis will be on the roles of finite inertia and clustering of cloud particles, and fluctuations of relative humidity coupled to particle growth by condensation.

Bio: Raymond Shaw is Distinguished Professor in the Department of Physics and director of the interdepartmental PhD program in Atmospheric Sciences at Michigan Technological University. His Ph.D. was received in 1998 from Penn State University, and his fields of study are cloud physics, atmospheric turbulence, and ice nucleation. He was a Postdoctoral Fellow in the Advanced Study Program at the National Center for Atmospheric Research and he is the recipient of a NSF CAREER award and a NASA New Investigator Program award. His ~100 publications span journals in fluid mechanics, optics, and atmospheric science, including a review paper published in Annual Review of Fluid Mechanics, papers in Science, PNAS, and PRL, and chapters in several published books.
