Tasmania 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.
For most of Australia's frost-prone areas the frost season has started later than any other year since 2007 but now it has arrived with a shudder.
Although temperatures across the southern states have been more seasonal over the recent days, temperatures along the eastern seaboard have remained quite balmy.
Water is flowing into outback Lake Eyre, but somewhat differently from past flooding of the remote saltpan, travel guide Rex Ellis says.
