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.
Engineers are frantically working to solve engine problems on the Royal Australian Navy's two largest ships, with fears the Landing Helicopter Docks (LHDs) could be out of action for several weeks.
The destructive core of Cyclone Debbie is already being felt along the north Queensland coastline, with wind gusts hitting Hamilton Island off the Whitsundays "like freight trains" and reports of roofs starting to lift in the Whitsundays.
International Space Station astronauts and NASA have captured incredible images of the size and fury of Cyclone Debbie off the coast of north Queensland.
