 note = {The tide of the idealized global ocean with a uniform depth is studied in terms of the resonance theory. The following results are found: 1. The period of the zonal free oscillations varies with the integer n which represents the oscillation mode in the north-south direction and the depth h of the ocean. In other words, the period becomes shorter as n becomes larger or the depth h becomes deeper. 2. In the case of oscillations other than zonal ones, the period is expressed explicitly by the depth h., 長崎大学教養部紀要. 自然科学篇. 1991, 32(1), p.1-5},
