Which meteorological element has the greatest impact on TAF interpretation?

Wind is indeed the meteorological element that has the greatest impact on TAF interpretation. In aviation, wind directly influences flight patterns, aircraft performance, and safety during both takeoff and landing. The wind speed and direction can determine the choice of runway at an airport, as aircraft typically take off and land into the wind to maximize lift.

Furthermore, changes in wind, especially during takeoff or landing phases, can impact the aircraft's handling characteristics. For instance, strong crosswinds or gusty wind conditions can complicate landing scenarios.

While temperature, pressure, and humidity are also important meteorological factors, they do not influence immediate flight operations and safety to the same extent as wind. Temperature can affect aircraft performance but is generally considered alongside wind conditions. Pressure affects local weather patterns but is not as critical for day-to-day flight operations. Humidity can influence visibility and the likelihood of weather phenomena, but again, wind remains the primary concern for pilots and air traffic control personnel when interpreting TAFs.
