Announcement: AGU session on Polar Amplification and its connection to lower-latitude weather and climate
Dear PAMIP colleagues,
We’d like to draw your attention to an AGU session: "Polar Amplification and its connection to lower-latitude weather and climate”. Please consider submitting an abstract to it. The abstract deadline is Wednesday, Aug 3, 2022. Further details can be found at
A078. - Polar amplification and its connection to lower-latitude weather and climate
Polar amplification is a prominent feature of climate change. It is closely associated with sea ice loss and may have implications to weather and climate globally. The Polar Amplification Model Intercomparison Project (PAMIP) is a coordinated set of model experiments, designed to advance understanding of the causes and effects of polar amplification. The goal of this session is to synthesize our current understanding of polar amplification, harnessing the PAMIP multi-model ensemble. Contributions from the following topics are encouraged: 1) What are the relative roles of atmospheric teleconnections versus local processes in causing Arctic and Antarctic sea ice loss and driving polar amplification? 2) How do the changes in polar sea ice impact the weather and climate in the lower latitudes, and via what mechanisms? We welcome studies using the PAMIP experiments, and also invite contributions from both idealized and comprehensive modeling studies, as well as observational/theoretical analyses.
Invited Speakers: Camille Li (University of Bergen), Robin Clancy (University of Washington)

Polar amplification, the phenomenon that external radiative forcing produces a larger change in surface temperature at high latitudes than the global average, is a key aspect of anthropogenic climate change but its causes and consequences are not fully understood.
The Polar Amplification Model Intercomparison Project (PAMIP), co-led by Dr. Doug Smith, Dr. James Screen, and Dr. Clara Deser seeks to improve our understanding of this phenomenon through a coordinated set of numerical model experiments. As one of the Coupled Model Intercomparison Project Phase 6 (CMIP6) endorsed MIPs, PAMIP will address the following primary questions:
- What are the relative roles of local sea ice and remote sea surface temperature changes in driving polar amplification?
- How does the global climate system respond to changes in Arctic and Antarctic sea ice?
