紀伊水道の OCEANIC FRONT の変動 -フェリーボートによる長期間の水温観測から-

Abstract

Using the surface water temperature recording on the commercial ferry boat, the variousmodes of the changing state of the oceanic front in Kii Channel have been studied.It is found that climatological condition in autumn and winter controls the intensity ofthe oceanic front.It is the most important that the oceanic front largely and repeatedly with the periodof about 15 days changes its intensity and position. It relates to the appearance of warmwater mass which seems to come from the Kuroshio along the east side of Kii ChannelApproach. The warm water mass also occurs the intrusion of water to the Tanabe Bay andlarge water exchange at the bay which have been observed at Shirahama OceanographicTower station.
