In TAF terminology, what does a "wind gust" represent?

In TAF terminology, a "wind gust" specifically refers to a brief increase in wind speed that is significantly higher than the sustained wind. Gusts are typically characterized by their short duration, often lasting only a few seconds, and they indicate variability in wind conditions at a given moment. This term contrasts with sustained winds, which represent the average speed over a longer period and do not encompass the rapid changes that gusts exhibit.

Understanding wind gusts is crucial for flight operations and safety assessments. Pilots must be aware of these fluctuations, as they can significantly affect aircraft handling and performance during takeoff and landing phases. The definition highlights the importance of distinguishing between different types of wind measurements to ensure accurate meteorological reporting and interpretation.
