At a given pressure level, the meridional convergence of angular momentum may be expressed in terms of the geostrophic wind components, and, in turn, by the Fourier analysis of the contour field. The contribution to the convergence of angular momentum at 500 mbs by waves of numbers 1 through 10 is computed for three ten-degree latitude belts for the period 1-20 January 1948. An attempt to correlate this convergence with the 24-hour change in zonal geostrophic wind speed for the 10-degree latitude belt is made The writer is deeply indebted to Professor F. L. Martin of the United States Naval Postgraduate School for his suggestion of the topic and his continued help throughout the investigation and during the preparation of this paper.
