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.
A cold front has brought snow to the Alps of New South Wales, priming a good weekend to hit the snow fields.
There's rarely a time when the world's driest continent is not faced with a drought.
Australia's ski resorts are finally becoming covered by fresh, natural snow, a result of the first decent cold blast in a few weeks.
