Seasonal Rainfall Zones
The seasonal rainfall maps use the differences between summer and winter rainfall across Australia to identify six major climate zones. These maps use the median annual rainfall (based on the 100 year period from 1900 to 1999) and seasonal incidence (the ratio of the median rainfall over the period November to April to the period May to October) to identify two major zones in the Burdekin Dry Tropics Region. Specific numerical rainfall thresholds are used to identify four sub-groups.
- Summer dominant
- summer dominant (more than 1200mm)
- summer dominant (650 - 1200mm)
- summer dominant (350 - 650mm)
- summer (350 - 650mm)
These two classification groups identify the season of highest rainfall in each area, and are similar in distribution to the annual and monthly rainfall maps.
