由于与白令海峡相关的向北的热和盐通量,白令海峡的水流对北半球当前的气候非常重要,古海洋学代理数据表明,它对该地区的古气候也至关重要。最近的理论研究表明,白令海峡的平均海洋条件只受到局地风和局地浮力的轻微影响。相反,主要的(负责任的)作用力据称是全球浮力场和全球风场。利用从简单的面向过程的数值模式到海洋环流和气候模式等一系列模式,为检验这一新观点提供了资金。该项目的具体目标是:1。以确定全球风场在决定白令海峡的流量中所起的作用;以确定最后一次冰期结束时的突然变暖是否部分原因是白令海峡的开放(由海平面上升引起)。
英文摘要
Because of its associated northward fluxes of heat and salt, the flow through the Bering Strait is important to the present climate of the northern hemisphere and paleoceanographic proxy data suggests that it has also been critical to the paleoclimate of the region. Recent theoretical work suggests that the mean oceanic conditions in the Bering Strait are only marginally affected by the local wind and local buoyancy forcing. Rather, the primary (responsible) forcings are purported to be the global buoyancy field and the global wind field. Funds are provided to examine this new idea using a hierarchy of models ranging from simple process-oriented numerical models to ocean general circulation and climate models. The project's specific goals are:i. to determine what role the global wind field plays in determining the flow rate through the Bering Strait, and ii. to determine whether the abrupt warming at the end of the last glaciation resulted in part from the opening of the Bering Strait (induced by sea level rise).
