Advancements in Observing and Modeling Processes and Coupled Feedbacks of the High-Latitude Earth Systems

Session ID#: 160188

Session Description:
Advanced understanding and prediction of an amplified response of the high-latitude Earth systems (HLES) to climate change requires progress in observing and modeling local processes and feedbacks and their linkages to lower latitudes. One of the challenges for measurements is to collect data on individual processes as well as their impacts within the fully coupled HLES and upscale them to basin-scale. A key challenge for Earth system models (ESMs) is to realistically represent the range of spatiotemporal scales and to improve parameterization of critical processes and feedbacks for climate-relevant predictions.

Given the recent field activities and advancements in the fidelity of ESMs and machine learning/artificial intelligence techniques, this session invites presentations on HLES studies from local events/processes, through their roles in the coupled system, to hemispheric perspectives. We also encourage presentations that advance understanding of polar extreme events, internal variability and forced trends, their predictability and linkages to lower latitudes.
