摘要
2012年7月现场调查了海南岛东部陆架海(琼东海域),结合其中4个断面的实测数据和卫星遥感数据,探究该海域2012年海表温度锋面的季节性变化以及夏季锋面结构特征。研究表明,琼东海域温度锋面的季节性变化明显,强锋面中心会随季节变化。夏季锋面主要分布在上升流区,是典型的上升流锋面,锋带宽20~40 km,大致沿100 m等深线,随深度增加锋面强度减小,位置向外海移动。
A hydrological investigation was conducted in the shelf of the eastern Hainan Island in July 2012. With the in-situ measurements from four cross-shelf sections and satellite data, the seasonal variability of sea surface thermal fronts and their structural characteristics of fronts are discussed. The results indicate that the seasonal variability of the thermal fronts is obvious, and the intense fronts are mostly distributed in the upwelling area, roughly following the 100 m isobath in summer. The width of the frontal zone is 20-40 km. With the increase of depth the fronts fade and the spatial position moves offshore.
