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.
With another earthquake of 5.7 magnitude being recorded today near off the southern Queensland coast, meteorologists and oceanographers are keeping a wary eye on the potential for tsunamis.
A series of strong cold fronts which are moving in quick succession over southeastern parts of Australia threaten to bring low level snow over the coming days to parts of Tasmania.
Adelaide has recorded its chilliest July in close to 20 years, with both maximum and minimum temperatures colder than average.
