CANCELLED: Food for thought talk on 6 Mar, 2014

I’m sorry that the talk has to be cancelled.

Talk: Climate Change Research

Speaker: Dr Andrew Friend, Department of Geography

Abstract: Andrew Friend from Department of Geography develops computational models of the effects of global change on terrestrial ecosystems and atmosphere. His current work is particularly concerned with the representation of physiological differences between plant types and species, the representation of competition, and the global-scaledynamics of biogeochemistry-climate interactions. Dr Friend leads the research which is part of the ‘Inter-Sectoral Impact Model Intercomparison Project’ (ISI-MIP) – a unique community-driven effort to bring research on climate change impacts to a new level.

Dr Friend will speak about his work within ISI -MIP project, what implications the recent findings have on the future of climate studies and the potential for this research feeding into climate policy.

Come along for this very special lunchtime talk to find out about the frontiers in climate research! Feel free to bring your own lunch, but light refreshments will be also provided.

1-2pm Thursday 6th Mar

TitleTropical Atlantic Ocean Impacts on Antarctic Peninsula Area Climate.

If you have a question about this talk, please contact Dr Dan Jones.

If external to BAS, please email the organiser in advance to gain access to the building.

Abstract: Antarctic climate in winter is known to be influenced, among other factors, by changes in radiative forcing and remote Pacific climate variability, but none explains the observed sea ice trend or Peninsula warming. Looking to the Tropical Atlantic, a leading mode of Sea Surface Temperature (SST) variability, the Atlantic Multi-decadal Oscillation (AMO), has been overlooked. We show that AMO related SST anomalies, particularly in the Tropical Atlantic, induce a positive phase response in the Southern Annular Mode, strengthen the Amundsen Sea Low, project onto the observed dipole-like sea-ice distribution between the Ross and Amundsen Seas, and contribute to Antarctic Peninsula warming. Support for these findings comes from analysis of observational and reanalysis data, and independently from atmospheric model simulations forced by specified SSTs. This study suggests that the Tropical/North Atlantic is important for projections of future climate variability of Antarctica, and has possible implications for the global thermohaline circulation and sea-level change.
