Western Australia North 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.
Trampolines have flown into powerlines and a lightning strike has reportedly caused a house fire as a severe thunderstorm tracked from Sydney all along the coast up to northern NSW on Monday afternoon.
Those who blamed last week's blackout in South Australia on renewable energy are dead wrong.
Thunderstorms are affecting six states and territories this afternoon, four of which are under warning for severe storms.
