New project: Atmosphere - Sea ice interactions in the new Arctic
My recent proposal to study cyclones in the Arctic and their coupling with sea ice has been approved for funding by the Norwegian Research council. The project will run from 2020 to 2023 and joins together sea ice modellers from the NeXtSIM modelling group with experts in Arctic atmospheric dynamics from the Geophysical Institute at the University in Bergen, along with some international collaborators.
We will use the PolarWRF atmospheric model in combination with the NeXtSIM sea ice model to simulate the rapid break-up events in sea ice caused by the passage of cyclones, and in turn we will investigate the effect of the breaking of sea ice cover on the cyclones.
Along the way we will create a new version of the sea ice model NeXtSIM that couples the sea ice model to an atmospheric boundary layer model, in order to account for the fast feedbacks between the sea ice state and the atmosphere.
