The speed of a weather front is primarily determined by upper-level winds, which drive its movement more than other factors like the Coriolis effect or temperature differential.
The speed of a weather front is primarily determined by the upper level wind. The winds at higher altitudes guide the movement of weather fronts, with faster upper-level winds typically driving fronts to move more rapidly across the landscape. Storm reports often indicate that a large difference in atmospheric pressure can result in strong winds, and these winds have significant implications for weather systems like hurricanes, which are influenced by the Coriolis effect. However, the specific speed of a weather front is influenced by the upper-level winds rather than the Coriolis effect, stability of air masses, or temperature differential alone.
