Estimating the Occurrence of Wind-Driven Coastal Upwelling Associated with “Aoshio” on the Northeast Shore of Tokyo Bay, Japan: An Analytical Model

Table 3

Comparison of the model with real cases of Aoshio observed on the northeast shore of Tokyo Bay from 2003 to 2010 (based on measured data from Chiba Light Beacon).
