Extratropical Climate Variability in the Coupled Ocean-Atmosphere System

9711750霍顿 PI将进行重点研究，以促进我们对热带外气候变化的理解。 主要重点将是大气年循环中的季节性变化。 季节变化研究将侧重于秋季和春季过渡季节的开始和结束、季节长度以及年度周期中其他相关变化的大规模方面。 在本研究中获得的季节性变化的描述和对相关动态的理解对于在以下方面推进海洋-大气气候系统的知识至关重要： 为发展热带外地区的季节预报提供了依据 了解整个年周期内海洋上的净大气事件 (i.e.,年际和年代际变化信号的强迫）。 这项研究很重要，因为它有可能促进对季节性气候变化及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.
