Wind shear is a change in wind speed and/or direction over a short distance. It can occur either horizontally or vertically and is most often associated with strong temperature inversions or density gradients.
Strong wind shears and gust would definitely be labeled as “Extreme Weather, use caution” in the ATIS if low visibility applies at the same time of the strong winds. Only used it once :)
Extremely important topic! Wind shear can quickly become dangerous if the correct actions aren’t taken due to the immediate change in airspeed, hence it’s a crucial go-around factor, also combined with an audio warning IRL as far as I am aware.
Thanks for the insights, very interesting!
