Interactions between Typhoon Choi-wan (2009) and the Kuroshio Extension System

Figure 1

Horizontal distributions of sea surface height anomalies observed by satellite altimeter (http://www.aviso.oceanobs.com/) at 7-day intervals between September 2 and September 30, 2009, which includes the period of the passage of Typhoon Choi-wan. The maps were created by using the delayed time reference series product of weekly mean sea level height. The contour interval is 10 cm. In each panel, the location of the KEO moored buoy is shown by the star. The track of Typhoon Choi-wan (from the Regional Specialized Regional Center (RSMC)—Tokyo best—track data set) is shown by black circles in two panels.
