    Data from the seven idealized climate model runs of Son and Lee (2005) [PDF], Son and Lee (2006) [PDF], and Son et al. (2008) [PDF]

    These model runs, referred to CS1, CS2,..,CS7, correspond to those combinations of the cooling and heating parameters, C and H, that are located along the diagonal in Fig. 4 of Son and Lee (2005) and Fig. 1 of Son and Lee (2006).


    CIRCUMGLOBAL WAVE PACKET INDICES

    The daily amplitude time series for the circumglobal wave packet (based on Feldstein and Dayan (2008)).
    This data is for the winter season, defined as the months of November through March, for the years 1958 through 2004. Please see [TXT] for a description of the methodology used to generate the circumglobal wave packet indices.

      The (a) pole position for December 1999 and (b) the pole position for the same month as determined by integrating the equatorial bulge torque forward in time. The degree of similarity between (a) and (b) is a measure of the extent to which polar motion is driven by the weather. The colors red, green, and blue indicate the first, middle, and last 10 ten days of the month, respectively. The units on the axes are mas (milliarcseconds), where 1.0 mas ~ 3.0 cm.
