How to forecast weather using a synoptic chart
Questions and Answers
The synoptic chart shows information that can be used to forecast the weather. This can be difficult, because there are a lot of different things that influence the weather. Even the experts sometimes get it wrong!
There are a few rules that help.
Rule 1: Highs normally mean hot days and cool nights in summer, and mild days and cold nights in winter. There will be light, or no wind, and clear skies. Lows mean stormy weather - strong winds, cloudy skies and rain, and usually mild temperatures.
Rule 2: A cold front means a rapid drop in temperature and brings strong winds (and often rain)
Rule 3: Isobars close together mean there are strong winds (because the air pressure is changing more rapidly in these areas)
Rule 4: In the southern hemisphere, the rotation of the earth causes air to flow clockwise around low pressure cells, and anticlockwise around high pressure cells.
Using these rules, forecast the weather conditions at Brisbane
Using these rules, forecast the weather conditions at Melbourne

Cyclones are intense low pressure systems in the tropics associated with very strong winds. Cyclones form over oceans and sometimes cause great damage when they reach land. Describe the location of the tropical cyclone on the above map.
