Statistical characteristics of austral summer cyclones in Southern Ocean
Characteristics of cyclones and explosively developing cyclones (or 'bombs') over the Southern Ocean in austral summer (December, January and February) from 2004 to 2008 are analyzed by using the Final Analysis (FNL) data produced by the National Centers for Environmental Prediction (NCEP)...
