Collaborative Research: Impact of Storm Activity on Recent Changes in Arctic Sea Ice Mass Balance

This project is to investigate impacts of changes in storm track dynamics on the recent rapid reduction in Arctic sea ice extent and volume. The increase of storm intensity and frequency result in enhanced high-frequency synoptic-scale variations and feedbacks in the Arctic climate system, and may make an integrative contribution to the basin-wide sea ice reduction. The project studies build upon previous work, and combine model simulations with satellite products and in situ observations to integrate and delineate physical causes of sea-ice mass balance changes in the context of storm-induced air-ice-sea interactions. This research will bridge synoptic-scale weather activities and large-scale climate variability and changes. The expected outcome includes assembled schematics linking storm-induced synoptic-scale variation with recently observed rapid loss of Arctic sea ice mass. Changes in sea ice concentration/extent, thickness/volume, and heat budget terms at the air-ice-sea interface that follow the motion of identified storms will be compiled.
