摘要：

通过WOA13 多年季节气候态数据分析了印度尼西亚5°S锋面与15°S锋面的季节变化特征及水平方向垂直方向上变化特点:两处海洋锋均在表层以下,其中5°S 附近仅有温度锋,主要存在于1—6 月份,1—3 月份为锋强度最大时期,集中在30—100 m水层内。15°S 处既存在温度锋又存在盐度锋,全年均有锋现象,但其强度存在季节差异。对比声速剖面,发现声速在从南到北穿越5°S(15°S)锋面时逐渐声速减小(增大)。

Based on the WOA13 seasonal climatic data, the change characteristics of vertical direction, horizontal direction and seasonal variation characteristics of Indonesia 5°S front and 15°S front were analyzed. Two kinds of ocean fronts were below the surface, and there is only the temperature front around 5°S from January to June, with the maximum front intensity from January to March and concentrated in the depth of 30-100 meters. Both the temperature front and salinity front exits around 15°S in the whole year,, but the intensity of fronts have seasonal variation characteristics. Through analyzing the vertical distribution of sound velocity, the results show that velocity of sound in the discovery from south to north through 5°S (15°S) front gradually when the sound velocity decreases (increases).
