The Wintertime Subtropical Current in the Northwestern Pacific
The strong wintertime westward current in the northwestern Pacific between 18°N and 23°N was investigated using data from satellite-tracked drifters. The decadal strengthening of the negative wind stress curl and trade wind in the subtropical area north of Hawaii and west of 150°E drives the decadal...
