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.
Tasmanian snow: Rescue effort underway to reach couple trapped in snowy central Tasmania; more snowfalls expected
A Tasmanian rescue helicopter has abandoned plans to winch out a couple trapped with their car in Mount Field national park after heavy snowfall in the state.
Rare snowfalls have blanketed the most unlikely parts of Tasmania, with farmers along the north-west coast waking up to white paddocks.
A former employee at the Grantham quarry has told the Queensland Floods Commission of Inquiry that quarry waste was not used to build embankment walls around the site.
