How are Southern Hemisphere seasons handled?
Each storm in the IBTrACS dataset was assigned a season, representative of its location and in accordance with WMO standards. Storms in the Northern Hemisphere follow the calendar year and storms in the Southern Hemisphere follow a 6-month offset year, from July to June. For example, the Southern Hemisphere 2008 season is spanned by 1 July 2007 to 30 June 2008.
