CAREER: Analysis of the Southern Hemisphere Annular Mode and Its Role in Climate Change

点击翻译按钮获取中文摘要

This NSF CAREER award supports the integration of scientific research and education within the context of developing a deeper understanding of climate processes. The research objective is to improve our understanding of large-scale climate variability in the Southern Hemisphere in the context of the Southern Hemisphere "annular oscillation" (AO), a robust feature of the atmosphere's general circulation that accounts for a substantial amount of climate variance. The education activities are the following: the development of new curriculum and mentoring of graduate students. This research is important because the AO, a natural mode of the atmosphere, has been shown to have a large influence on weather and climate; however, the basic processes that control its development and characteristics are poorly understood and controversial.
