Description

Abstract:: The Arctic is entering a new era characterized by thinner ice, decreased ice extent, and changing weather. Even during extreme events, such as Arctic cyclones, these dynamics exhibit significant variations. Such variations will induce notable changes in sea ice dynamics, including sea ice motion, transport, and distribution, resulting in new trends in sea ice melting. This study investigates the effects of Arctic cyclones on sea ice motion through simulations and observations. We first employed ERA5 data to examine Arctic cyclone structure and dynamics, comparing them to the Rankine vortex model. The retrieved idealized cyclone velocity fields were then used to estimate the upper ocean velocity fields beneath the sea ice. Numerical simulations of sea ice with the wind cyclone and upper ocean fields were conducted using the Subzero discrete-element sea ice model to examine sea ice trajectories under cyclones. The size of the ice floe and the turning angle between the ice and wind field affect the trajectory. The model simulates the motion of pieces of sea ice in response to the wind and ocean currents. This study provides insights into how cyclones influence sea ice motion and ocean dynamics and their potential contribution to sea ice melting.
