III. Book web pages:

  1. Course Textbook: Global Atmospheric Circulations, by R. Grotjahn, Oxford Univ. Press, 1993
      The book has an extensive errata that I strongly encourage people to consult. This document is more than an errata, it includes new material that significantly upgrades the presentation of several sections of the book. The errata & upgrade is offered as a single pdf file to allow greek letters and math symbols to be displayed. (updated 17 December 2004)
