New South Wales/ACT 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.
An independent climatologist says a change in the weather pattern could be fantastic news for farmers who need winter rain.
A Red Centre cattle station has decided to bring forward its muster because of continuing rain.
Significantly less rainfall has fallen this May across coastal Queensland, although there were patches of high totals in the northern parts.
