GC41B:
Mechanisms and Impacts of Natural and Anthropogenic Tropical Pacific Decadal Variations and Trends II Posters

Submit an Abstract to this Session



Session ID#: 26317

Session Description:
Decadal variations in the tropical Pacific coupled ocean-atmosphere system have climate impacts around the globe, potentially influencing ENSO, monsoons, droughts, polar climates, and modulating global temperature trends. Current research has led to improved understanding of tropical decadal processes, such as: natural (solar, volcanic) and anthropogenic (aerosol and greenhouse gas) forcing; internal oceanic dynamics; extratropical-tropical atmospheric, oceanic, and land interactions; and noise processes on a variety of time scales. Characterizing forced long-term tropical Pacific changes remains an important challenge.

Papers are invited on causes, predictability, and global impacts of decadal to centennial climate variability, both forced and unforced, in the tropical Pacific. Observational and modelling studies are both welcome. Contributions utilizing paleoclimate reconstructions, instrumental observations, future projections based on numerical models, and theoretical models are welcome, as are methodological papers aimed at assessing and/or improving tropical Pacific near-term forecasting, including studying model bias and initialization shock.
