WebThe two major ways thunderstorms move are via advection of the wind and propagation along outflow boundaries towards sources of greater heat and moisture. Many thunderstorms move with the mean wind speed through the Earth's troposphere, or the lowest 8 kilometres (5.0 mi) of the Earth's atmosphere.
WebJul 27, 2024 · An outflow boundary is created when a thunderstorm produces a downdraft of air that crashes into the ground and spreads out, away from the storm. The downdraft consists of rain-cooled air falling from a storm, since it is more dense than the surrounding air.
