Victoria Sea Surface Temperature Anomalies
The sea surface temperature anomaly (SSTA) is the difference between the observed SST and the climatological SST. These anomalies are calculated on a weekly basis.
Positive SSTAs are usually correlated with increased regions of convection (cloudiness and rainfall) while negative SSTAs are usually correlated to reduced convection.
SSTAs can be used as an indicator of the phase of global climate fluctuations, such as the El Nino/Southern Oscillation (ENSO).
The data displayed in this map is the weekly average, centred on the date shown.
Residents are warned to take care outdoors as snow, hail and wind gusts send Tasmania into a big chill.
Following an uncharacteristically warm week for southeastern Australia, a solid line of cold fronts are on the way to bring us back to winter with a bang.
The fact that Terra Australis is a land of extremes is not a new concept.
