  • How Does Wildfire Smoke Travel?

    The bigger the wildfire, the more likely the smoke will travel farther from the source. Why? The smoke from a wildfire typically gets shot up into the sky vertically, after which it expands outward into a plume. These monstrous clouds of smoke are called pyrocumulonimbus clouds. For this reason, the air quality in the region directly surrounding a wildfire may not be as bad as in the downwind areas. After shooting high up into the atmosphere, sometimes even as far as the stratosphere, the smoke moves outward horizontally, landing on top of cities.
