Maximum current speed distribution of ocean surface currents measured with high frequency surface wave radar during the period of severe tropical storm Lionrock

The maximum current speed distribution of ocean surface currents during the period of severe tropical storm Lionrock is investigated using six days' currents data measured by High Frequency Surface Wave Radar (HFSWR) in the southwestern Taiwan Straits. Analysis shows that an increment up to about 100-cm/s is induced by the Lionrock at the southern and northeastern area, and the increment is nearly symmetrical about the track of Lionrock. The increments of the maximum currents are larger at the right of the track of Lionrock than that of the left.
