Southern Ocean Cyclone Study
Interactions between small scale cyclones and sea ice and their role in the Southern Ocean climate system
Small (< 2000 km across) cyclones over the Southern Ocean represent an important element in
the global circulations of heat and moisture and hence the maintenance of Southern Hemisphere
climate. The primary objectives of this project are to advance the understanding of atmospheric
processes responsible for the development and decay of small Southern Ocean cyclones and to
explore the interactions between these cyclones and the underlying surface conditions, including
sea ice extent, thickness, concentration, motion, and temperature. To attain these objectives we
propose to use satellite imagery and datasets, archived output and new experiments from a
numerical weather prediction model, and many pre-existing in-situ observations.
