Weather Stations and Station Models

What does a circle surrounding a station in a station model plot indicate?

A. Strong winds

B. Calm winds

C. Extreme temperatures

D. Severe thunderstorms

Answer:

The circle surrounding the station in the station model plot indicates calm winds.

Station models are graphical representations used to display weather conditions at a specific location on a weather map. In these station models, various symbols are utilized to provide information about temperature, pressure, wind speed, wind direction, and other meteorological parameters.

When a station does not have a wind barb or feather present, and instead has a circle surrounding it in the station model plot, it indicates that the station is experiencing calm winds. Calm winds refer to wind speeds less than 1 knot, which is too weak to produce a wind barb or feather symbol.

Therefore, in the context of station models, the presence of a circle around a station signifies that the winds at that location are very weak or nonexistent. This information is crucial for understanding the current weather conditions and making accurate weather predictions.
