Overall, these results are encouraging for the future of Antarctic sea ice predictions. There are many remaining questions related to sea ice predicability, data assimilation, and Southern Ocean coupled processes. Please get in touch if you are interested in discussing more!.

We found notable forecast errors in regions of oceanic deep convection and strong northward sea ice drift. Improving model representations of Southern Ocean mixing and sea ice dynamics will be critical for improving sea ice predictions.

Summer prediction skill is associated with the persistence and drift of sea ice thickness anomalies (leads >= 3 months), as well as the persistence of sea ice extent anomalies (leads of 0-2 months).

Exploring the physical mechanisms that underpin this prediction skill, we found that winter skill is primarily attributable to zonally advected upper ocean heat content anomalies (lead times of >= 2 months) and the persistence of sea ice extent anomalies (leads of 0-1 months).

We find skillful regional predictions at least 11 months in advance for autumn and winter sea ice, and skill up to 9 months in advance for spring and summer sea ice. In general, these skill horizons for Antarctic sea ice are longer than what has been found for Arctic predictions.

Can Antarctic sea ice be predicted on the seasonal timescale? We have a new paper out in @AMSJCLi that shows the answer is "yes" in three GFDL dynamical prediction systems: (open access).w/ @AlexHaumann @mjharriso @Skapnick @kaichihtseng and many others.

Interested in how volcanic eruptions impact sea ice? Check out our new paper, led by @andrewp109 and with @drseaice. Hemispherically symmetric volcanic forcing leads to a highly asymmetric response in sea ice!.
New paper out! In this work with @_the_iceman and @drseaice, we use the exciting new abundance of GCM large ensembles to show that the differing N vs. S Hemisphere response to Pinatubo is robust across models.
