What are the symbols that are found in the synoptic chart?
A synoptic chart is any map that summarises atmospheric conditions over a wide area at a given time. It displays information on temperature, precipitation, wind speed and direction, atmospheric pressure and cloud coverage, all observed from many different weather stations, aeroplanes, balloons and satellites.
What is surface synoptic chart?
A synoptic chart is any map that summarises atmospheric conditions (temperature, precipitation, wind speed and direction, atmospheric pressure and cloud coverage) over a wide area at a given time.

How do you use a synoptic chart?
How to read synoptic weather charts
- Pressure pattern. The circular lines you see on the chart are isobars, which join areas of the same barometric pressure.
- Cold fronts and warm fronts. Also on a synoptic chart are the lines, triangles and semi-circles representing ‘fronts’.
- Warm and cold fronts.
- Occluded fronts.
- Troughs.
How do you read weather numbers?
The higher number is the forecast maximum temperature for the day. The lower number is the minimum temperature. Take note of the forecast weather conditions. Symbols like sunshine or lightning are self-explanatory.
What is synoptic pattern?
The word ‘synoptic’ simply means a summary of the current situation. In weather terms, this means the pressure pattern, fronts, wind direction and speed and how they will change and evolve over the coming few days.
Why are synoptic charts useful?
Synoptic charts provide information on the distribution, movement and patterns of air pressure, rainfall, wind and temperature. This information is conveyed using symbols, which are explained in a legend. Synoptic charts are used to report on the current weather and to predict future weather patterns.
How do you read weather pressure?
A barometric reading below 29.80 inHg is generally considered low, and low pressure is associated with warm air and rainstorms….Low Pressure
- Rising or steady pressure indicates clearing and cooler weather.
- Slowly falling pressure indicates rain.
- Rapidly falling pressure indicates a storm is coming.
