How it works:

CSIRO Atmospheric Research (CAR) short term weather forecast data (8 days ahead) are plotted by EWN Publishing against NEMMCO's (the National Electricity Market Management Company's) official STPASA (Short Term Projected Assessment of System Adequacy) data for the corresponding state regions.

NEMMCO uses forecasts provided by the Bureau of Metereology (BOM) in projecting system adequacy. eWeather provides the NEMMCO data updated in real-time, along with the alternate weather forecast modelling provided by CAR.

New seasonal forecasts:

The CSIRO Division of Atmospheric Research also provides year-ahead seasonal temperature forecasts, based on sea surface temperatures in the Pacific and the El Nino Southern Oscilation (ENSO).

This offers a new way to view future temperature deviations on a quarterly seasonal basis. For more information about the atmospheric modelling used by CAR in their forecasts, please see the About Long Term Forecasts page.
