Australia 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.
Damaging winds are forecast to affect Victoria for the second time in two days as a cold front moves into the Bight.
For many Tasmanians it will be no surprise the heavy rains since the beginning of May have set a new three-month record, before the end of the period.
A flood watch is current in the Mount Lofty Ranges near Adelaide as another cold front approaches the region.
