Abstract

Abstract

Based on the CTD data of PN Section provided by Japanese Oceanographic Data Center, the current velocity of ninety cruises during 1991 to 2011 are calculated with dynamic height method. The structure, maximum velocity, flux and width of the current are analyzed. The results show that there are three kinds of typical current structure of Kuroshio at PN Section, which are single core structure, double-core structure and multi-core structure. The occurrence probability of single core, double-core and multi-core are 50%, 39% and 11% respectively. The current structure of Kuroshio at PN section exhibits significant seasonal variation. In autumn, the probability of occurrence of multi-core structure reaches its maximum, and the quarterly average of current core number is greater than other seasons. In winter, multi-core structure never emerges and single core structure occurs more often than any other structures, and the quarterly average of current core number is less than other seasons. All kinds of current structure occur in spring and summer. The quarterly average of current core number of spring and summer are between autumn and winter. The flux of Kuroshio at PN Section exhibits seasonal variation too. The flux reaches the largest in winter and summer, and smallest in autumn. Seasonal variation also occurs in maximum velocity and current width of Kuroshio at PN Section, which are the largest in summer and the smallest in autumn, followed by spring and winter.
