Global circulation models

---

There are a lot of bits and pieces that go into a global circulation model, and many of them remain quite independent of one another until it all has to be put together in algorithms and implementations. That makes this a good opportunity for experimentation with the construction of multiply connected documents in which some of the parts can be encountered by following links along quite different paths.

Topics will be introduced as soon as rough drafts are ready, and for now, things will be subdivided in the following categories (more change is probable):



• Fluid mechanics on the rotating geoid.
  
• Generalities about conservation laws (html).
  
• A vertical structure model (html).
  
• Energy in a fluid layer (html).
  
• Nonrotating shallow atmospheres (html).
  
• Rotating shallow atmospheres (html).
  
• Linear models (html).
  
• Thermodynamics of atmospheres (dvi) (ps) .
  
• A computational grid for spheres.
  Maps of spheres onto octahedrons (html).
  Stitching the patches (html).
  Faux cubic interpolation on patches (html).
  
  
• Computational algorithms.
  
• Implementations.
  
• A working model.


Caution: Equations in the html-documents have been tuned to look best on Internet Explorer 6. They also can be made made to look quite good on current versions of Mozilla and Netscape browsers by following the directions here. Netscape Navigator 4 can veiw them, but not very well.
