Abstract: The formation of the Kuroshio large meander in summer 2004 was investigatedby using the cruise data, Argo profiles data, and satellite remote sensingdata.
We validated the point that cyclonic eddy contributes to the largemeander.
Besides, the impacts of typhoons on Kuroshio meanders were studied.From 29 July to 4 August, the typhoons stirred the ocean and upwelled thedeep water, which enhanced the existed cyclonic eddy, and immediately made adrastic meander of the Kuroshio.
Moreover, the unexpected typhoons in June 2004also contributed to the initial meander at Tokara Strait.
The result suggestsan alternative meander mechanism of Kuroshio path via typhoon-eddy-Kuroshiointeractions.
It is argued that typhoons accompanied with cyclonic eddies,might play crucial roles in meanders of the Kuroshio.
This will provide a morecomprehensive understanding of the dynamics of the west boundary flows like theKuroshio and the Gulf Stream, and will be useful in eddy-resolution models.
