Abstract

 Data from drifters of the surface velocity program and tropical cyclones (TCs) of the Joint Typhoon Warning Center during 1985-2009 were analyzed to demonstrate strong currents under various storm intensities such as category-4 to -5, category-2 to -3, and tropical storm to category-1 TCs in the northwestern Pacific. Current speeds over 2.0 m s(-1) are observed under major TCs with the strongest mean currents to the right of the storm track. This study provides the characterization of the near-surface velocity response to all recorded TCs, and agrees roughly with Geisler's theory (1970). Our observations also verify earlier modeling results of Price (1983).
