Arctic Feedbacks Stopping Winter Sea-Ice Refreezing: Part 1 of 2 // Apr 18, 2019
I discuss the very latest cutting edge scientific understanding on a powerful Arctic feedback that keeps regions of open, ice-free Arctic from refreezing during the dead of winter–December 1st to February 28th:
- Albedo feedbacks are NOT happening at this time since the Arctic is in total 24/7 darkness.
- What IS happening: turbulent heat flux (sensible + latent) plus increased upwelling long-wave radiation brings heat from the ocean up into the lowest 1.5 km of the atmosphere;
- More downwelling long-wave radiation prevents sea-ice formation.
- This feedback increased 8.9% per year from 1979 to 2016.
