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 very cold airmass coupled with vigorous a low pressure system caused snow to fall to low levels in Tasmania last night and into this morning, leading to road delays and closures.
