sawylSo far, the presentations have been a bit of a mixed bag but then they always are. By far the best so far was Richard Peltier's opener in which he talked about three GFD projects being run out of the U of T.
The first application was an attempt to model the Younger-Dryas reversal using CCSM3, which showed a THC shutdown due to a large influx of melt water from the north into the arctic, rather than into the atlantic from the west as had been previously thought. The second example involved using full non-hydrostatic CFD to model the deep shell of the jovian atmosphere in an attempt to learn more about the atmospheric banding. Interesting, if math heavy, stuff. I thought that the third example, using unstructured meshes with coupled ocean models was just the coolest thing. They seem to have come up with a way of running long scale integrations in a way that preserves the energy balance of the model, but which still lets them crank up the resolution in some areas to the point where they can resolve eddies. When they compared the output to a 1/8 degree model, they found that they got pretty much the same results, but for a much lower computational cost. How cool is that?
Anyway, enough science stuff, I'm off on a tour in half an hour and then I'm going out with the Australian contingent (and Stuart and his wife). Should be fun...
