TitleTropical Atlantic Ocean Impacts on Antarctic Peninsula Area Climate.

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

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.

Seminar: Cambridge Centre for Climate Science

Thursday 10 Oct:  Cambridge Centre for Climate Science- 14:00-18:00

Venue: McGrath Centre, St Catharine’s College, Cambridge.

Speaker: Prof Gabi Hegerl, Prof Ted Shepherd, Prof Mat Collins, Prof David Vaughan.

TitleIPCC Fifth Assessment Report: what have we learned, and where do we go next?

If you have a question about this talk, please contact Dr Amanda Maycock.

To mark the release of the IPCC WG1 Fifth Assessment Report, we have invited some of the UK’s leading climate science experts to talk about the key new findings from the report and discuss where the field might be headed next.
