    Summer study program in geophysical fluid dynamics : dynamic differentation
    (Woods Hole Oceanographic Institution, 1984-11) Malkus, Willem V. R. ; Mellor, Florence K.
    Those attending G.F.D. 1984 were introduced to the novel topic of Geological Fluid Mechanics by our Principal Lecturer, Herbert Huppert. He presented his studies both as a discipline with recent fascinating successes, and as a challenge to his listeners to further isolate mathematically tractable examples of these multi-component flows. Geological Fluid Mechanics has been the responsible process for the formation and modification of most of the geological objects studied today. The dynamics of fluid mixtures in magma chambers, the changing fluid boundary conditions and composition during selective crystallization of parts of the melt, and the separation of fluid fractions of different density and viscosity all represent areas in which quantitative theories are currently being tested. However, equally many areas, including convection mechanisms in the Earth's core and quantitative predictions for upper mantle motion, resist simplistic modeling.

    1980 summer study program in geophysical fluid dynamics : coherent features in geophysical flows
    (Woods Hole Oceanographic Institution, 1980-11) Veronis, George ; Mellor, Florence K.
    Four principal lecturers shored the task of presenting the subject "Coherent Features in Geophysical Flows" to the participants of the twenty-second geophysical fluid dynamics summer program. Glenn Flierl introduced the topic and the Kortweg-de Vries equation via a model of finite amplitude motions on the beta plane. He extended the analysis to more complex flows in the ocean and the atmosphere and in the process treated motions of very large amplitude. Larry Redekopp's three lectures summarized an extensive body of the mathematical literature on coherent features. Andrew Ingersoll focussed on the many fascinating features in Jupiter's atmosphere. Joseph Keller supplemented an interesting summary of laboratory observations with suggestive models for treating the flows.

    1982 summer study program in geophysical fluid dynamics : particle motions in fluids
    (Woods Hole Oceanographic Institution, 1982-11) Veronis, George ; Mellor, Florence K.
    The (Lagrangian) motion of a fluid particle was contrasted with the (Eulerian) flow past a fixed point in space during this twenty-fourth summer program in geophysical fluid dynamics at the Woods Hole Oceanographic Institution.

    1979 summer study program in geophysical fluid dynamics : the Woods Hole Oceanographic Institution : notes on polar oceanography
    (Woods Hole Oceanographic Institution, 1979-11) Stern, Melvin E. ; Mellor, Florence K.
    The emphasis in this year's GFD program has been somewhat different from the past. We have tried to expose a theoretically oriented audience to the new body of observations pertaining to the Arctic and Antarctic circulation. We have, however, not departed from our traditional goal of encouraging broad based inquiries into the field of Geophysical Fluid Dynamics. We would like to believe that the breadth of interest and enthusiasm exhibited in these reports will stimulate future work in Polar Oceanography and Fluid Dynamics.

    1981 summer study program in geophysical fluid dynamics : physics of convection
    (Woods Hole Oceanographic Institution, 1981-11) Malkus, Willem V. R. ; Mellor, Florence K.
    Reexploring convection and its various transitions to chaotic behavior were the central themes of GFD 1981. Our principal lecturer, Dr. Edward A. Spiegel, provided both a rich historical picture and stimulating hours at the current frontiers of this topic. Before the summer was out his research lecture on "A Tale of Two Methods" elegantly merged Pierre Coullet's canonical formalism for studying dynamical systems in a central manifold and the more traditional two-timing amplitude expansions near critical points. Other lecture sequences on convection and its relation to simpler dynamical systems ranged from the fine presentations of John Guckenheimer on bifurcation theory to Fritz Busse's survey of his immense contributions to our understanding of nonlinear convection. The list of other lectures found on the following pages attests to our summer-long exposure to convection in the ocean, the atmosphere, the earth's core and mantle, and in the sun. August brought lectures on new observations of convection in the laboratories of physicists. Albert Libchaber's precise experiments on the many routes convection can take to turbulence, with parallel laboratory and numerical experiments described by J. Gollub and E. Siggia, added much to our language of inquiry.

    Summer study program in Geophysical Fluid Dynamics : baroclinic instability and ocean fronts
    (Woods Hole Oceanographic Institution, 1983-11) Stern, Melvin E. ; Mellor, Florence K.
    "Baroclinic instability as the largest scale of motion participating in the cross frontal oceanic transport process" was the theme of the 25th summer program at G.F.D. Killworth (Cambridge University) reviewed classical baroclinic instability theory, leading up to recent studies in which the distinctive structure of an ocean front is included. Finite amplitude baroclinic instability in the classical model was discussed by Pedlosky (WHOI). Laboratory experiments on baroclinic frontal theory was surveyed by Griffiths (Australian National University). The different kinds of oceanic fronts were surveyed by Joyce (WHOI), and additional observations were supplied by several of the invited staff. The smallest scales of motion relevant to the cross-frontal transfer problem were discussed from the oceanic standpoint by Osborn (Naval Postgraduate School) and from the point of view of laboratory experiments by Ruddick (Dalhousie University), among others.
