What is the typical horizontal and vertical extent of a microburst?

The correct answer describes the typical dimensions of a microburst accurately. A microburst is a small-scale downdraft that occurs within a thunderstorm and can result in severe wind shear, making it particularly hazardous for aircraft during takeoff and landing.

Typically, the horizontal extent of a microburst is around 1 mile, and the vertical extent can reach up to approximately 1000 feet. This means that when the downward burst of air hits the ground, it can spread out in a radius of about 1 mile, while the vertical component can influence the air up to 1000 feet above the ground.

Understanding these dimensions is essential for pilots and operators, as microbursts can create sudden, dangerous changes in wind direction and intensity, potentially leading to loss of control of an aircraft if they are not adequately prepared or informed.
