摘要

Prydz Bay, Antarctica, is partially covered by sea ice throughout the year. The distribution of sea ice and its annual variation are mainly controlled by meteorological conditions and ocean currents. A high-resolution regional ice-ocean coupled model is developed for the study of seasonal sea ice variation in Prydz Bay. The model domain encompasses Prydz Bay with a resolution of 1/6°×1/12°. Forcing fields are computed from 6-hourly NCEP reanalysis. Seasonal sea ice variation characteristics and typical polynyas are well reproduced. Ice over 1.5-m-thick piles up at the east end of the West Ice Shelf (WIS) as a result of the westward coastal current. The ocean-to-ice heat transfer parameterization has a significant influence on the sea ice evolution in the melting season. Comparison experiments show that atmosphere and ocean dynamics, combined with complex coastal topography, play an important role in the large-scale sea ice distribution along the coast.
