Air-sea interaction between Tropical Cyclone Nari and Kuroshio
No full text[[abstract]]The air-sea interaction between tropical cyclone Nari
(Sep/6 – 16/2001) and Kuroshio is studied using satellite
observations and an ocean model. Nari crossed the
Kuroshio several times, which caused variations in
typhoon intensity. Nari weakened when it was over the
shelf north of Kuroshio where cooling took place due to
mixing of the shallow thermocline. The cyclonic circulation
penetrated much deeper for the slowly-moving storm,
regardless of Nari’s intensity. Near-inertial oscillations are
simulated by the model in terms of the vertical
displacement of isotherms. The SST cooling caused by
upwelling and vertical mixing is effective in cooling the
upper ocean several days after the storm had passed. At
certain locations, surface chlorophyll-a concentration
increases significantly after Nari’s departure. Upwelling
and mixing bring nutrient-rich subsurface water to the sea
surface, causing enhancement of phytoplankton bloom.
Seasonal to interannual variations in the intensity and central position of the surface Kuroshio east of Taiwan
No full text[[abstract]]Seasonal and interannual changes of surface Kuroshio intensity and central position east of Taiwan during 1993–2012 are investigated by quantitatively analyzing the satellite altimetry product. The Kuroshio moves inshore (offshore) off northeast of Taiwan in winter (summer), whereas it has an offshore (inshore) path off southeast of Taiwan in winter (summer). The seasonal change of heat flux over the East China Sea shelf is found to cause the seasonality of the Kuroshio central position off northeast of Taiwan, whereas the seasonal Kuroshio movement off southeast of Taiwan is found to be induced by the combined effect of the Kuroshio changes through the Luzon Strait and the eastern Luzon Island. In contrast to this y-dependent path changes, the Kuroshio becomes weaker (stronger) as a whole east of Taiwan in winter (summer). On the interannual time scales, the Kuroshio throughout the eastern coast of Taiwan intensifies and has a concurrent offshore path during the periods of 1995–1997 and 2004–2007. The relative intensity of cyclonic eddies to anticyclonic eddies off eastern Taiwan are found to contribute to these interannual Kuroshio changes.
