How fast do the katabatic winds blow?

Katabatic winds can vary significantly in speed, typically ranging from 20 to 60 miles per hour (32 to 97 kilometers per hour), but they can occasionally exceed 100 miles per hour (161 kilometers per hour) in extreme cases. These winds occur when cold, dense air flows down a slope under the influence of gravity, often found in polar regions or mountainous areas. The speed can be influenced by factors such as terrain, temperature gradients, and weather conditions.
