This webinar will provide an overview of a newly developed dynamical seasonal prediction system and its performance in predicting regional Arctic sea-ice conditions.

Registration is required.

This webinar is designed for the sea-ice research community and others interested in information about applications of machine learning in sea-ice forecasting. While this is an open event, attendees are advised that the discussions will largely be of a technical nature.

Webinar Abstract

The rapid decline of Arctic sea ice and the implications for a broad array of stakeholders have spurred a decade of research activity into sea ice predictability and prediction. In this talk, I will introduce a newly developed dynamical seasonal prediction system, GFDL-SPEAR, and assess the performance of this system for regional sea ice predictions. I will discuss the key physical sources of Arctic sea ice predictability, routes to improving sea ice predictions, and fundamental limits on prediction skill. Advancing dynamical Arctic sea ice prediction capabilities will require coordinated efforts between the modeling, observational, and data assimilation communities.

In recent decades we have seen major changes in Arctic Ocean circulation, salinity, and temperature and associated declines in sea ice coverage and thickness. There is evidence of connections of these changes with climate indices, and the changes arguably affect climate by altering the radiative heat balance at high latitudes, impacting the strength of the global overturning circulation, and influencing the interaction between the ocean and Greenland ice sheet. There are also indications that Arctic sea ice and atmospheric circulation can play an important role in extended range predictability of extreme weather events in mid-latitudes. In spite of its importance, Arctic Ocean observations are limited. Several major in situ observing programs that existed in the 2000s have ended, and today sustained oceanographic observations outside the Canada Basin have almost ceased to exist. This workshop will aim to assess our understanding of the Arctic Ocean circulation and discuss observing system requirements needed to confirm and extend that understanding.

More specifically, the workshop will explore changes in Arctic Ocean and sub-Arctic seas circulation related to global change and the observing system required to track those changes in the future. The observing system design effort will be cognizant of the practical, geopolitical, and operational constraints of Arctic Ocean observing, but will incorporate modern objective experimental design and data assimilation using numerical models as fundamental guiding principles. Its work will contribute to evaluations of model simulations and observational analyses to assess opportunities for model improvements.

The US CLIVAR Observing, Modeling, and Understanding the Circulation of the Arctic Ocean and Sub-Arctic Seas Workshop will include presentations addressing:

A. The state of knowledge of Arctic Ocean and sub-Arctic seas circulation with an eye toward identifying critical gaps in observations of modes of variability
B. The observing system needs and data assimilation approach to track those modes of variability
C. The practical, institutional, technical, and geopolitical challenges of increasing the coverage of Arctic Ocean observations that are required by A) and B)

US-SCAR is hosting a meeting for US scientists who are conducting research in, from or about Antarctica and the Southern Ocean. Scientists interested in getting involved in Antarctic research through US programs are also welcome and encouraged to attend. This conference is open to all US scientists and anyone interested in US Antarctic research. There is no registration fee.

The meeting will provide opportunities for US Antarctic scientists to get together and present their work, and for early career researchers and others new to Antarctic science to learn about SCAR and the various resources available to US scientists for Antarctic-related research. There will be a mix of Lightning Talks, panels and social activities for the US Antarctic Community to meet and interact.

The meeting and associated events will be on Zoom. The schedule (see below) is set for two hours each day (one hour science and one hour panel) with additional time added for socializing. The panels will have brief presentations by panelists, and most of the time will be devoted to questions and discussion.

Abstract submission deadline: 21 June 2021.

Registration deadline: 9 July 2021.

Postponed. New dates will be 27-30 June, 2022.

This workshop was originally scheduled for 20-23 October, 2020, and then 12-15 July, 2021.
