Reflections from AGU24 - The importance of communicating scientific uncertainty for cryospheric hazards

2024 was a record year for drastic changes in the cryosphere. Against this backdrop, the annual American Geophysical Union (AGU) 2024 Fall Meeting took place in Washington DC from 9 to 13 December 2024, with many sessions focused on improving our monitoring of, as well as our response to, rapid changes in the cryosphere. There, Dina Abdel-Fattah, Manager of the PCAPS International Coordination Office, presented her work on the glacial lake outburst floods in Juneau, Alaska, in collaboration with partners from the University of Alaska Southeast and the National Weather Service in Juneau. Malte Müller, leader of the WWRP/PCAPS endorsed project on the Svalbard Marginal Ice Zone campaign, also presented on the project at AGU.

Reflections from Arctic Partnership Week 2024: The growing role of AI in sea ice prediction in a rapidly changing Arctic

As the Arctic undergoes rapid transformation with unprecedented sea ice retreat, it has become both a stark symbol of climate change and an urgent reminder of our need for accurate prediction systems. During the 2024 Arctic Partnership Week (10-12 December 2024, Busan), discussions were centred on sustainable solutions for the changing Arctic. PCAPS Steering Group member Clare Eayrs from the Korea Polar Research Institute participated in two key sessions during “Knowledge Day”: the “Arctic Youth Dialogue” and a KMI-Arctic Frontiers session on “Sustainable Arctic Seas: AI and Environmental Protection”.

From ships to shores: The new high-Arctic IWIN weather station network in Svalbard

Over the last three years, an innovative weather station network, the Isfjorden Weather Information Network (IWIN), has been established in Svalbard's Isfjorden region. Led by the University Centre in Svalbard (UNIS) and supported by MET Norway, IWIN expands on the relatively sparse existing network of operational weather stations by installing compact, all-in-one weather stations on lighthouses and tourist cruise ships. IWIN has a strong potential to improve weather forecasting and enhance safety and research in the region. It also serves as an example for how the coverage of in-situ weather data can be enhanced elsewhere in the Arctic. Both of these aspects support PCAPS goal to improve weather observations and weather forecasting in the polar regions.

Inuit user needs documented across Nunavut, Canada: Reports release key messages for polar environmental service providers

Canadian reports were recently released in September 2024, providing valuable insights into Inuit uses and local needs for weather, water, ice, and climate information and services. This is the first academic-community partnership to undertake a comprehensive survey of user needs across the territory of Nunavut. Results are critical to inform infrastructure, personnel, and forecasting investments tailored to Inuit priorities in the Canadian Arctic. This ties into PCAPS’ efforts to promote research that helps to enable improved prediction services in the polar regions, to better support human and environmental well-being.

Importance of high-resolution regional atmospheric modelling for the polar regions: Insights from the Polar CORDEX project

Users in polar regions are increasingly asking for more granulated, higher-resolution weather forecasts and climate predictions at grid-spacings of 1-10 km, which presents a major challenge for the current and next generation of atmospheric models. The World Weather Research Programme (WWRP) aims to address this challenge through the Polar Coupled Analysis Prediction for Services (PCAPS) project. Dr Andrew Orr - who is a climate scientist at the British Antarctic Survey, a member of the PCAPS steering group, the coordinator of the Polar Coordinated Regional Climate Downscaling Experiment (Polar CORDEX) project, and the investigator for the Polar Regions in the Earth System (PolarRES) project - reflects on how high-resolution regional atmospheric modelling is being used to address these challenges and help improve our understanding and decisions related to the polar regions.
