Abstract: | By using existing data obtained in the offshore area from the Boso Peninsula to the Joban Coast, it was shown that the double
structure of the Kuroshio Front — which is usually found along the northern edge of the Kuroshio Extension to the east 143°E
(Nagataet al., 1986 ; Shinet al., 1988) — is hardly found at the edge of the Kuroshio when it is flowing along the Japanese coast or in the area to the west
of 142°E. It was suggested that the cold and fresh water core beneath the density front of the double structure originates
from the fresh and cold Oyashio Water which is captured beneath the Kuroshio Front just off the Kashima Coast. The double
structure of the Kuroshio Front would be generated and developed very rapidly in the region between 142°E and 143°E just after
the Kuroshio leaves the Japanese coast. |
