海冰盐度的时空变化对海冰和海洋特征的影响尚未得到详细研究,因为现有的气候模式忽略或歪曲了这一过程。为了解决这个问题,本文制定了一个参数化更现实的海冰盐度预算,并检查海冰和海洋模拟的敏感性,冰盐度变化和相关的盐通量进入海洋使用耦合的全球气候模式。结果表明,包括这样一个参数化导致的增加和增厚的海冰在欧亚北极和南极绕极区的冰盖内,北大西洋深层水的减弱和加强南极底层水。最后讨论了与冰变化有关的大气响应。
The impacts of the spatiotemporal variations of sea ice salinity on sea ice and ocean characteristics have not been studied in detail, as the existing climate models neglect or misrepresent this process. To address this issue, this paper formulated a parameterization with more realistic sea ice salinity budget, and examined the sensitivity of sea ice and ocean simulations to the ice salinity variations and associated salt flux into the ocean using a coupled global climate model. Results show that the inclusion of such a parameterization leads to an increase and thickening of sea ice in the Eurasian Arctic and within the ice pack in the Antarctic circumpolar region, and a weakening of the North Atlantic Deep Water and a strengthening of the Antarctic Bottom Water. The atmospheric responses associated with the ice changes were also discussed.
