Geostrophic relative vorticity is computed along three latitude circles generally encompassing the United States, using a Fourier analysis of the 500-mb height field for the period 3-6 November 1961. A statistical comparison of vorticity obtained in this manner with its square grid computation is made. The writer are 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.
