利用温度剖面资料结合海面高度估算全球海洋上层热含量异常
Keywords: argo资料,卫星高度计,热含量,全球海洋
Abstract:
？利用全球海洋约200万条温度剖面结合海面高度资料,估算了1993—2009年全球海洋0—750m层的热含量异常。分析表明,仅使用剖面温度资料估算的全球海洋上层热含量可以反映出大部分海区热含量的十年变化信号,除了资料稀疏的海区(如南大洋)。全球0—750m海洋上层在1993—2009年的平均增暖速率约1.17w·m-2,增暖最显著的海区出现在40os附近。全球海洋热储年际变化中大的信号基本上与厄尔尼诺南方涛动(enso)相关。热带海洋的热含量变化相对比较稳定。中、高纬海区,特别是南大洋中、高纬海区的热含量增加速度在2001年后超过了热带海区。随着全球argo实时海洋观测网的建成,其资料量将大大超过过去几十年的总量,结合jason/topex卫星高度计资料数据,可以用来精确估算全球海洋上层热含量的变化,为全球气候变化系统研究提供重要科学依据。
