Fig. 2 The variation of the position of the Kuroshio axis on each standard line shown in Fig. 1 The distance (km) measured from the coast is taken in the ordinate. The thick curve indicates the one-year running averaged position. The horizontal black and white bars in bottom column indicate the period of the large meander path and that of the straight path, respectively : the identification of the flow path in the upper column is based on the description in the Prompt Report, and that in the lower column was made by FUJITA. Four large meander events(a, b, c and d)were defined by FUJITA in the period from 1975 to 1994. (FUJITA, 1997)
