What does a "wind shift" signify?

A "wind shift" signifies a change in wind direction. This occurs when winds that were blowing from one direction begin to flow from a different direction. Such shifts can indicate various meteorological phenomena, such as the passage of cold fronts, warm fronts, or changes in local weather conditions. While a change in wind intensity could occur alongside a wind shift, it is not the primary definition of the term. In the context of meteorology, being aware of wind shifts is crucial as they can provide important information about potential changes in the weather, including the development of storms or other significant weather changes. Thus, understanding wind direction changes is essential for weather observation and forecasting.
