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.
While a wet and stormy winter has many South Australians counting the days until summer, flooding at Langhorne Creek south of Adelaide has grape growers smiling.
Safety concerns have held up remediation works at the Myer store redevelopment in the Hobart CBD, which has been flooded after a rivulet wall collapsed.
Conditions are set to take a turn for the worse over the weekend as a cold front bears down on southwestern WA.
