1990年代，世界海洋状况发生了重大变化。特别是，北大西洋经历了快速变暖，副极地环流区域的海面温度在短短几年内上升了1°C。与SST模式的变化相关的是地表气候的变化，特别是北美地区在所有季节都有温暖和干燥的趋势，欧洲地区有暖泉的春天和潮湿的夏天。在这里，在何种程度上初始化使用的海洋状态的观测气候预测系统能够捕获所观察到的季节平均地面气候的变化进行了研究。这项研究不是研究20世纪90年代中期北大西洋变暖事件本身的预测，而是比较了变暖之前和之后开始的后报，相对于不吸收信息的后报。结果表明，后报捕捉到了观测到的季节平均地面气候变化的许多方面，特别是…
AbstractDuring the 1990s there was a major change in the state of the world's oceans. In particular, the North Atlantic underwent a rapid warming, with sea surface temperatures (SSTs) in the subpolar gyre region increasing by 1°C in just a few years. Associated with the changes in SST patterns were changes in the surface climate, in particular, a tendency for warm and dry conditions over areas of North America in all seasons, and warm springs and wet summers over areas of Europe. Here, the extent to which a climate prediction system initialized using observations of the ocean state is able to capture the observed changes in seasonal mean surface climate is investigated. Rather than examining predictions of the mid-1990s North Atlantic warming event itself, this study compares hindcasts started before and after the warming, relative to hindcasts that do not assimilate information. It is demonstrated that the hindcasts capture many aspects of the observed changes in seasonal mean surface climate, especially...
