Extratropical Climate Variability in the Coupled Ocean-Atmosphere System

9711750霍顿国际和平研究所将进行有重点的研究，以促进我们对温带外气候变化的理解。主要重点将放在大气年周期的季节变化上。季节变率研究将集中在秋季和春季过渡季的开始和结束、季节的长度以及年度循环中其他相关变率的大尺度方面。在这项研究中，对季节变化的描述和对相关动态的了解对于增进对海洋-大气气候系统在以下方面的知识至关重要：了解大气环流状态的转变，为在温带以外地区发展季节预报提供基础；了解整个年度周期(即，强迫年际和年代际变化信号)上的海洋净大气事件。这项研究之所以重要，是因为它有可能促进对季节性气候变化、其原因和物理学的理解。

9711750 Houghton The PIs will conduct focused studies to advance our understanding of climate variability in the extratropics. The primary emphasis will be on the seasonal variability in the atmospheric annual cycle. The seasonal variability research will focus on large-scale aspects for the onset and ending of the fall and spring transition seasons, length of the seasons, and other relevant variability in the annual cycle. Description of seasonal variability and understanding of the relevant dynamics that will be gained in this research is essential for advancing knowledge of the ocean-atmospheric climate system in aspects such as: Understanding transitions in atmospheric circulation states Giving a basis for developing seasonal forecasting in the extratropics Understanding the net atmospheric events on the ocean over the full annual cycle (i.e., forcing of interannual and decadal variability signals). This research is important because it has the potential to advance the understanding of seasonal climate variability, its causes and physics.
