Northern Territory 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.
Melbourne has had its coldest day since last September, with heavy rain and flurries in Alpine areas.
For those among us wanting to balance out our participation in Earth Hour, the Vivid Light, Music and Ideas Festival opens in Sydney this on Friday.
Australia's Bureau of Meteorology (BoM) has released modelling showing the latest El Nino cycle is over, but could now lead to a wet winter after a devastating 14 months of drought and famine across the Pacific.
