Global 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.
Canberra has chilled below freezing every morning this month, and a few days have been quite cold as well.
Over the last week, much of the southeast has been treated to cold, cloud-free nights with light winds.
There have been a few hiccups along the way but the school garden at St Francis' Primary School in Hughenden continues to grow despite the on-going drought.
