Seminar: Dr. Ying Li

Please join us as we welcome Dr. Ying Li from the Deptartment of Atmospheric Science at Colorado State University for a seminar titled "Two way interactions between clouds and large-scale extratropical atmospheric circulation". Coffee will be served.

Abstract

Large scale patterns of climate variability have been widely examined in the context of dry atmospheric dynamics but less so in the context of two-way interactions with clouds. In this talk I will present the emerging evidence for feedbacks between large scale climate variability and cloud processes at extratropical latitudes. Observational analyses reveal that large-scale patterns of climate variability have a pronounced signature not only in cloud incidence but also in cloud radiative forcing. Numerical experiments suggest that cloud processes, in turn, may play a key role in determining the structure and amplitude of hemispheric scale dynamic variability. Implications for trends in the large-scale atmospheric circulation in a warmer climate are discussed.
