What Does a Weather Station Symbol with Only a Circle Represent?

What does it mean when a weather station symbol only has a circle?

When you encounter a weather station symbol with only a circle, it signifies that the station is currently experiencing calm conditions with minimal or no significant wind movement.

Understanding Weather Station Symbols

In meteorology and weather station symbols, the wind barb is a graphical representation used to indicate wind speed and direction. The circle without any attached barbs or feathers represents calm or light winds, indicating that there is little to no significant wind movement at that particular station during the observation period. Here's a breakdown of the symbolism: - Calm Winds (Circle Only): When you see only a circle on a weather map or station, it means that the wind speed at that location is essentially negligible. There is very little or no detectable wind. - Varying Winds (Barbs or Feathers): If you see barbs or feathers attached to the circle, it indicates varying wind speeds and directions. The number and orientation of the barbs or feathers provide information about the wind's speed and direction. - Strong Winds (Long Barbs or Feathers): Long barbs or feathers indicate strong winds. The longer the barbs or feathers, the higher the wind speed.
