Figure 2: Time series of the Kuroshio transport (solid line with dots; in Sv) south of Japan during 1992-1999, estimated from TOPEX/POSEIDON altimeter data using the relationship between the transport and sea-surface height difference. A Gaussian 3-point filter with weights (0.25:0.5:0.25) has been used. Panel (a) is the transport of the eastward flowing Kuroshio. Also shown are transports (red dots) estimated from in situ data. Panel (b) is the throughflow transport of the Kuroshio (see text for definition).
