Session JMS018: High Latitude Modes of Climate Variability

Session Description:
The climates of the Arctic and Antarctic are governed by the large-scale
modes of atmospheric variability such as the Northern and Southern
Annular Modes (NAM/SAM) and the El Nino-Southern Oscillation that is
manifested in high latitudes by the Pacific-North American and
Pacific-South American (PNA/PSA) patterns. The session will concern how
these patterns are changing and affecting high latitude climate, how the
different modes interact and the mechanisms by which this occurs, the
roles of high latitude versus tropical forcing, the roles of the ocean
and sea ice cover in initiating and/or amplifying change, stratospheric
versus tropospheric causes of variability, and the issue of natural
versus anthropogenic forcing. The impacts of the Pacific Decadal
Oscillation and the Atlantic Multidecadal Oscillation will also be
explored. Contributions are solicited on these topics, including
observational studies using reanalyses and ice-core records, theoretical
investigations, and all types of numerical modeling.
