Instability analysis of terrain-induced canopy flows


School of Earth and Environmental Sciences, Queens College at City University of New York


Responsibilities: We seek a creative post-doctoral scientist who will apply a nonlinear dynamic approach to the study of canopy flow instability over complex terrain. Turbulent transport processes occurring within canopies are extremely complex, especially for ecosystems with hilly or mountainous terrain, and have not been accurately represented in models. Better understanding of these transport processes in complex terrain is important for understanding the role of terrain in the introduction of pollutants into the atmosphere, and the transfer of water and carbon dioxide between soil, vegetation, and the atmosphere.The overall goal of this project is to develop analytical approaches for understanding instability conditions between different regimes of canopy flows over complex terrain. To address this goal, specific tasks are to: (1) derive analytical criteria for transition conditions between different regimes of terrain-induced canopy flows; (2) verify the analytical results using computational fluid dynamics; and (3) validate the analytical and numerical results using field observations.


Qualifications: PhD in one of the following specialties: non-equilibrium statistical physics, theoretical physics, computational physics, fluid mechanics, or applied mathematics. Experience in computational fluid dynamics (CFD) or large eddy simulation also is desirable. Applicant must have a strong background in theoretical physics/applied mathematics. How strong is strong enough? For example, applicants are qualified to apply for this position if s/he is able to derive and understand all formula in the following paper: Jackson, P. S. and J. C. R. Hunt, 1975: Turbulent wind flow over a low hill. Quarterly Journal of the Royal Meteorological Society, 101, 929-955. Applicants should be enthusiastic and highly motivated, and a strong publication record is expected.
