摘要

摘要: 耳状锋面是黄海冬季的一个重要的海洋现象，它是由黄海暖流和山东沿岸流交汇形成的，具有空间尺度大、强度强等特点。长时间序列的现场观测资料和再分析资料均显示耳状锋面的强度在上世纪50年代至90年代期间发生了显著的减弱，并且这种减弱的趋势在黄海冬季季风速的多年代际变化中也得以体现。通过数值试验发现，冬季季风的减弱导致在黄海形成了一个顺时针的环流异常：中国沿岸浅水海域为向北的环流异常，而在黄海中部为向南的环流异常。该环流异常场的分布总体上与黄海冬季的平均环流场相反，使得黄海的环流在该季节总体表现为减弱，特别是山东沿岸流和黄海暖流的减弱，从而导致了耳状锋面强度的减弱。由于耳状锋面在黄海的局域海洋动力过程及海气相互作用中扮演着重要角色，因此它的减弱对于黄海冬季局地气候的多年代际变化有着重要影响。

Abstract: The ear-shaped thermal front (ESTF), formed by the convergence of the Yellow Sea Warm Current (YSWC) and the Shandong Coastal Current (SCC), is a very important oceanic phenomenon in the Yellow Sea (YS) in winter. In situ measurements and reanalysis datasets all demonstrate that the ESTF has been weakening during 1950s-1990s, and a similar weakening trend is also found in winter monsoon over the YS. Numerical experiments show that the weakening of winter monsoon can induce an anomalous circulation in the YS on multi-decadal timescale with northward anomalous currents along China's coast and southward anomalous currents in the central YS—generally opposite to seasonal mean circulation. The anomalous circulation causes slowdown of the YSWC and the SCC, and thus weakens the ESTF. Since the ESTF plays important roles in regional ocean dynamics and air-sea interactions, its weakening has important implications for regional climate in the YS in winter.
