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.
A front is bringing a colder showery change to southern Australia, dropping temperatures by five-to-10 degrees.
Some inland areas of Northern Queensland have had their coldest April morning in at least 60 years.
Large areas of southern Australia can expect a foggy start to the next few mornings, reducing visibility for the first few hours, even in the southeastern capitals.
