Global 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.
Parts of Victoria, Tasmania and South Australia could be lashed by storms and damaging winds on Thursday as a cold front sweeps across Australia's southeast.
It is storm season in Australia and, while being struck by lightning is considered a rare occurrence, there are several steps people can take to keep safe.
