Considerable attention is being directed at the present time toward fluctuations in sea level as related to the dynamics of the oceans and, to a lesser degree, the dynamics of the atmosphere. Most of the work along these lines, however, has been concerned with seasonal rather than nonperiodic variations. Nevertheless, an analysis of sea level data compiled over a period of many years at four California tidal stations indicates that non-periodic fluctuations of considerable magnitude also occur. Since these fluctuations are probably the direct or indirect result of variations in certain meteorological elements, it becomes of interest to investigate the nature of those atmospheric changes that occur simultaneously with changes in sea level.
