J. Stewart TURNER

Emeritus Professor and Visiting Fellow

Research School of Earth Sciences

Research Interests:

 Dynamical processes in the atmosphere, the ocean and the solid earth. These have been studied using small-scale laboratory experiments and associated theoretical models to understand the basic physics and dynamics of natural phenomena. Topics of special interest are convection and mixing, especially in stably stratified fluids.

1952 B.Sc. University of Sydney. First Class honours in Theoretical Physics, University Medal and John Coutts Scholarship.

1953 M.Sc. University of Sydney. Research Studentship of the University of Sydney, thesis on nuclear scattering.

1957 Ph.D. University of Cambridge. Thesis entitled "Dynamical aspects of cloud physics", under the supervision of Dr A.A. Townsend and Sir Geoffrey Taylor.
