High-Latitude Earth Systems – From Process-Level Understanding to Advanced Regional Predictive Capabilities
Session ID#: 82278
Session Description:
The dynamics of polar regions is of high societal relevance due to their response to, and impact on, global climate change, including sea level rise, atmosphere/ocean heat transport, carbon storage, extreme events, etc. To address such issues, advancements are required in process-level understanding and coupling within the high-latitude Earth systems, integrating observational and modeling efforts from regional to global scales.
This session focuses on progress and challenges in observing and modeling the high-latitude environment, including syntheses of field measurements and modeling, and Coupled Model Intercomparison Project Phase 6 (CMIP6) results. We solicit presentations that advance understanding of (i) the operation of individual components of the polar Earth systems and their coupling, (ii) internal and external drivers of polar climate change, and (iii) their linkages to lower latitudes and to extreme events. Contributions on (iv) reducing model biases and (v) uncertainty in prediction of future high-latitude change are also strongly encouraged.
