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.
Heavy rains across Tasmania could bring relief for the state's farmers and severely depleted hydroelectric dams.
Strong winds and heavy rain lashed parts of Victoria overnight, with hundreds of residents calling the State Emergency Service (SES) for help.
In India, 330 million people across 10 states are in the grip of a crippling drought and heatwave.
