The Kuroshio Extension and its recirculation gyres

摘要: This paper reports on the strength and structure of Kuroshio Extension its recirculation gyres. In time average, quasi-permanent gyres are found to north south jet. The characteristics these recirculations determined from combined observations System Study (KESS) field program (June 2004–June 2006) include current meters, pressure recording inverted echo sounders, subsurface floats. position simulated by a highresolution numerical model be consistent with observations. circulation pattern that is revealed complex system multiple embedded in crests troughs meanders Extension. At location KESS array, jet transport about 114 Sv. represents 2.7-fold increase compared Kuroshio’s at Cape Ashizuri before it separates coast flows eastward into open ocean. enhancement current’s comes development flanking Estimates an array sounders high-resolution ocean general similar magnitude.
