CORE.v2是单独海洋环流模式常用的强迫场,其微弱的偏差会造成模拟结果巨大的差异。因此,本文使用单独的海洋环流模式LICOM2.0对CORE.v2的强迫场进行了验证。结果表明,在北大西洋和太平洋的副热带区域的淡水通量有使海表盐度变淡的偏差的作用,这可能是由于CORE.v2中的弱的表面风,强的比湿或者过多的降水所造成的。另外,在北大西洋高纬度区域的海表盐度变淡的偏差主要是与海洋动力学过程有关而非强迫场所造成的。
CORE.v2 is a commonly used forced field in a single ocean circulation model and its faint bias can cause a huge difference in simulation results. Therefore, this article validates the forced field of CORE.v2 using a separate ocean circulation model LICOM2.0. The results show that freshwater fluxes in the subtropical regions of the North Atlantic and the Pacific have the effect of diluting the sea surface salinity which may be due to weak surface winds in CORE.v2, strong specific humidity or excessive Caused by precipitation In addition, variations in the salinity of the sea surface in the high latitudes of the North Atlantic are mainly related to the process of ocean dynamics rather than to forcing sites.
