Project information
Project aim
The subantarctic region is frequently subject to violent small storms which often arrive with little warning. The most extreme of these are referred to as 'polar lows', and are accompanied by very strong surface winds. They present serious hazards to shipping and are difficult to forecast. The project will make use high-resolution satellite-derived surface winds over the Southern Ocean to identify these features. Complementary satellite data will be used to determine the temperature and moisture vertical profiles within these systems. This information will allow an identification of the physical processes operating and hence offer the potential for improved forecasting.
