How do I interpret a synoptic chart?
A synoptic chart uses isobars (lines of equal pressure) to map high and low systems. Closer isobars mean stronger winds. Cold fronts appear as blue lines with triangles; warm fronts as red lines with semi-circles. For a 10 day synoptic chart australia, the Bureau of Meteorology publishes forecasts four times daily. Regional maps, such as weather maps nsw and weather maps qld, are also available through the Bureau.
