A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.

Isobars
Isobars are the plain lines curving across the map. They connect points with the same mean sea level air pressure (weight per square area of air above). Some isobars have numbers on them showing this value in hectopascals (hPa). Isobars indicate the flow of air around weather systems. You can broadly interpret wind strength and direction from these maps. The general rule is that winds are strongest where the isobars are closest together. Thus, the strongest winds are usually near cold fronts,...
High and low pressure systems
The number shown on high and low pressure systems indicate the central mean sea level pressure. Standard pressure at sea level is defined as 1013 hPa, but there's no specific value that defines high vs low pressure—it's all relative to the surrounding environment. A typical high is around 1020 hPa or higher, while a shallow low is usually above 1000 hPa, a moderate low 980–1000 hPa, and a deep or intense low below 980 hPa. An intense cyclone could even have a central low pressure of around 96...
Troughs
A trough appears on the weather map as a dashed blue line on the chart. It is an elongated area where atmospheric pressure is low relative to its immediate surroundings. Like cold fronts, troughs separate two different air masses (usually more moist air on one side and drier air on the other). As the trough moves towards the moist air it lifts it. This causes cloud or even showers and thunderstorms to develop. If the trough moves back in the other direction it will drag the moist air with it....
We use a wide range of weather information from our observations network to prepare a weather map. This includes observations from over 700 automated weather stations across Australia, Antarctica and offshore islands. We also use information provided by ships equipped with weather stations, and meteorological drifting buoys. Every day at over 30 lo...
Weather maps may present the current situation, what's happened in the past (a synoptic analysis) or show a forecast for the next few days (a synoptic outlook or prognosis). It can be useful to look at multiple maps in sequence to show movement and change. For today and the previous six days, see the latest mean sea level pressure analysis. To find...
