I have engaged in studies of variability of the Antarctic atmosphere-ocean-sea ice system and its role in global climate since 1995. My research has progressed from the identification of polar-global linkages, expanded to an ENSO-Antarctic Dipole teleconnection mechanism study, and finally resulted in an Antarctic sea ice forecast. At the same time, I have utilized space-born scatterometer observations and developed a series of studies focused on air-sea interactions on synoptic time scales, ranging from cyclone-sea ice interaction, high wind evaluations to satellite enhanced cyclone statistics in the Southern Ocean. With the accumulation of knowledge regarding climate variability in the atmosphere, sea ice and at the air-sea interface, an understanding of the ocean’s role in the mid-high latitudes climate system becomes increasingly important. However, this task is much more challenging because of sparse observations in the Southern Ocean. In recent years, I have developed a few oceanic field programs to advance our knowledge of how the polar ocean plays out in the climate system.

Fields of Interest

My primary research interests includes the climate variability in the Arctic/Antarcitc atmosphere, ocean, sea ice and glacial ice fields, connection between the tropics and polar region, and sea ice predictability.
