The final version of the manuscript benefited substantially from reviews provided by Gerry Bell, Chet Ropelewski, Ed Schneider, Tom Smith, and an anonymous reviewer. The multiple-month window analyses that proved enormously useful in bolstering the credibility of many new results were done at the urging of Mike Wallace. Likewise, conversations with Dave Montroy and his associates have mutually strengthened our work. Finally, M. M. and H. R. have been partially supported by NOAA’s Office of Global Programs.
