地球潮汐への海洋潮汐の影響に関する一考察

Abstract

The Arctic Ocean, Sea of Okhotsk, Yellow Sea, East China Sea and the western half of SetoNaikai do not exert significant influences on the earth tides in Kyoto compared with the PacificOcean, judging from their location and size. The effects of ocean tides in seas farther than adistance of 4000 or 1000 km from Kyoto are concluded to be negligible in cases of tilt or strain tide, respectively, while more distant oceans must be taken into consideration in the case of gravity tidein Kyoto. The effect of the M2 ocean tide on the gravity tide in Kyushu is larger than that inHokkaido due to dominant effects of the northwestern part of the Pacific Ocean and the EastChina Sea in Kyushu; the effect of the Sea of Japan is unexpectedly small.
