Abstract: The basic data used in this project is the (US) National Centers for Environmental Prediction global reanalysis data set, and we have used the area south of 30S. Two primary data sets have come from the project. The first is the amplitude and phase of the surface semiannual oscillation over the Southern Hemisphere. The second is comprehensive statistics on cyclone behaviour over the hemisphere ... View entire text
