Flat or exposed ground experienced the prevailing wind. Deeply incised valleys are prone to wind channeling - the wind is steered up or down stream, which may be different to the prevailing wind.
Mid-slopes may experience lee-eddy winds if they face downwind and the prevailing winds exceed around 25 km/hr.
By reading the colours it is possible to anticipate complexities in the wind field at a fire ground. Note that there are currently some linear anomalies in NE NSW - use care in interpretation.

This map is based on a standard 1:100,000 scale map tile (ref: GeoScience Australia), outlines in grey. Grid north is to the top of the page. Note your local variations for true and magnetic north before using those.
The limited annotation data are from GA's 1:1,000,000 scale products.
This map shows a 10km map grid, on the relevant MGA94 Zone. All elevation data uses SRTM v2 data.
