New computer model forecast map services

During August 2010, the Bureau will be upgrading its computer forecast model to provide an expanded range of attractively presented maps of wind and wave conditions for the next 7 days.

Key changes that you will notice on the Marine website include:

  • Forecast wave and weather maps will be extended to cover the next 7 days.
  • A new interface to display maps of swell, wind wave, and significant wave height at particular times during the next 7 days.
  • Wave maps will be available in colour instead of black and white.
  • The Marine wind map interfaces will be upgraded to include the new model information for the first two days from early August 2010.

Background information on the new computer model

From 17 August 2010, the Bureau of Meteorology will no longer run the GASP, LAPS, TLAPS and Meso-LAPS family of computer forecasting models.

A new computer forecasting model (ACCESS) will be implemented from late June 2010 as the replacement. The performance of the ACCESS model represents a significant leap forward in terms of forecasting abilities over the Australian Region.

The Bureau is also upgrading its wave model to Wavewatch III, using wind information from the ACCESS model. Early performance results indicate that the new wave model is now 25% better at predicting swell heights two days in advance.
