What are Weather Circles?
Synoptic charts often have symbols describing the weather conditions at different locations. A weather circle provides five pieces of information about the weather in a place:
- wind speed
- wind direction
- cloud coverage
Weather circles present data collected from various sources, including weather stations, aeroplanes, balloons, and satellites.
