What does the contraction "VRB" signify in a Terminal Aerodrome Forecast?

The contraction "VRB" in a Terminal Aerodrome Forecast specifically signifies that the wind direction is variable. This indicates that the wind is not consistently coming from one specific direction but rather fluctuates, which can be important information for pilots and air traffic control when planning for takeoff, landing, and flight paths. Understanding wind patterns is crucial in aviation for safety and operational efficiency. Knowing that the wind direction is variable helps aviators adjust their strategies accordingly, as changes in wind direction can affect aircraft performance and navigation.
