| what is:
"Seasonal Climate Outlook" ? |
| The term "Seasonal Climate" refers
to what the weather was, is, is-likely-to-be for a particular season. The
"Outlook" is based on the Southern
Oscillation Index (SOI), Sea-Surface
Temperature (SST) patterns in the Pacific Ocean are also important in
driving climate variability and are useful guides to potential climate patterns
in Australia (and other parts of the world too). One rainfall probability system used in Queensland is the "SOI
Phase System", the current "Outlook
Message" gives commentary on the seasonal outlook and additional information may be found at the Queensland Climate Change Centre of Excellence. You will also
find the "Winter
Crop Outlook" on the Department of Primary Industries web site. |
