摘要 利用涡扩散法、海面高度资料和气候水文资料,对孟加拉湾海域海盆尺度涡(湍流)致热盐输运进行了估算.结果发现,在孟加拉湾大量的涡致输运主要存在于4个区域:孟加拉湾北部的西部边界(NB)、孟加拉湾西部(WB)、斯里兰卡南部和东部(SWB)以及孟加拉湾东南部靠近马六甲海峡区域(SEB).根据涡输运的气候态分布,涡致热输运主要存在于NB和SWB海域,而涡致盐输运主要存在于NB、SWB和SEB海域.基于季节平均的涡致输运估计, NB和SWB海域涡致热输运较为显著的季节为初夏和夏季季风季节,而在WB和SEB海域为后夏季风季节.此外,季节性涡流动能(EKE)调制通过季节性强化的东印度洋沿岸流(EICC)和西南/东北季风电流(SMC/NMC),被确定为影响季节性涡流的主要因素之一,在NB、WB和SWB区域分别进行运输.
