Abstract
A clear-cut case of dispersion of energy downstream in the mid-tropospheric long-wave pattern during the first two weeks of November 1951 is examined with the help of plots of meridional wind components. The dispersion could be traced over more than half the hemisphere traveling with a speed about twice that of the zonal wind at 700-mb. Calculations of group velocity based on Rossby's work show good agreement with observed values of the speed of dispersion.Keywords
