Duane E. Stevens, Ph.D.
Atmospheric Dynamics, Numerical Weather Prediction
I am interested in the geophysical fluid dynamics of
circulations in the atmosphere and ocean. Recent publications have
treated fluid instabilities at large scales in middle latitude and at much
smaller scales in the outflow layer of hurricanes. I have developed
a dynamical system to investigate slowly evolving tropical circulations
and applied it to the zonally symmetric Hadley circulation. I am
interested in tropical waves as well as ocean/air interactions. I
have also begun a set of investigations into the atmospheric around the
Hawaiian islands. The weather and climate of the Hawaiian islands
are being studied with a complex three-dimensional model which includes
detailed physical processes.
