Australia 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.

A hot and cold heart
14:22 EST
Alice Springs sits at the centre. Geographically, the town is roughly 1500 km equidistant from both Darwin and Adelaide. Culturally, it demarcates 'up north' from 'down south'. And meteorologically, at 23 degrees latitude, it separates the tropics from the mid-latitudes, marking the general limit for the reach of southern cold-fronts.
