Cyclone occurrence and frequency in East Antarctica

I have been looking into the effect of weather systems, cyclones, on surface processes in Antarctica. Unfortunately, weather and climate data are not always that readily available. Having read some papers by Dr Petteri Uotila and colleagues at the University of Melbourne and CSIRO in Australia I emailed Dr. Uotila and asked if he had cyclone data he was willing to share. Dr Uotila kindly shared his data with me in an excellent example of scientific cooperation.

This has allowed us to map the passing of cyclones along the coast of Dronning Maud Land (Figure 1). These data we will use to compare with surface snowpack observations and satellite data.

Cyclone data from P. Uotila (Melbourne/CSIRO)

If you want to know more about cyclone tracking and the effects of circulation on the ice sheet read Dr Uotila’s paper:
