Dale Durran is currently the chairman of the Department of Atmospheric Sciences at the
University of Washington, one of the world's leading atmospheric science departments.
Professor Durran received a Master's degree in Mathematics from the University of
California at Berkeley, and a Ph.D in Meteorology from the Massachusetts Institute of
Technology.Much of his research has focused on the influence of mountains on
the atmosphere and on numerical methods for simulating atmospheric flows.

Durran's research on the flow over mountains includes studies of mountain waves, downslope
winds and rotor circulations, the influence of mountain-wave induced drag on the larger
scale flow, and orographic precipitation. His work on numerical methods includes
the formulation of wave absorbing boundary conditions for limited area models and the
development of approximate sets of governing equations for the accurate and efficient
modeling of low-Mach-number disturbances in compressible stratified fluids.
Recently he has been investigating the dynamics of very thin tropical cirrus
clouds that appear to play an important role in the transport of water vapor into
the stratosphere (thereby influencing the chemistry and radiative heating in that region).

Durran has written one graduate-level textbook, Numerical Methods for Wave Equations
in Geophysical Fluid Dynamics, authored 79 peer-reviewed publications and created a
high-definition time-lapse movie of mountain wave clouds. He has supervised 10 Ph.D
students most of whom are currently university professors or researchers in government
labs. Durran is a Fellow of the American Meteorological Society.
