Short summary
This study investigates the role of atmospheric dynamics in sea-ice thickness and snow depth at a coastal site in East Antarctica using in situ measurements and numerical modeling. The snow thickness variability is impacted by atmospheric forcing, with significant contributions from precipitation, Foehn effects, blowing snow, and episodic warm and moist air intrusions, which led to changes of up to 0.08 m within a day for a field that is in the range of 0.02–0.18 m during July–November 2022.
