An example of seasonal variations in surface oceanic circulation is revealed from the data off the California coasts. An account for them may probably be given by a simple model in which the rearrangement of density through wind-induced vertical motion is essential to the changes. This mechanism might also apply more widely to annual variations in oceanic circulation in response to those in atmospheric pressure field. An emphasis may be placed on ihe point that the variations in currents are in quasi-stationary balance with pressure field in the ocean surface layer which varies as integral effect of winds. A possibility of quantitative prediction might be suggested.
