Weather Extremes Induced by Large Pyrocumulonimbus Smoke Events
Abstract
Towering thunderstorms triggered by intense wildfires (known as pyrocumulonimbus or pyroCb) act as giant chimneys, injecting large quantities of smoke particles high into the atmosphere every year. These smoke particles absorb solar radiation, thereby altering temperature, vertical motion, and horizontal circulation. Here, we examine if the heating perturbation induced by large smoke plumes in the lower stratosphere significantly influences dynamic circulation in the atmosphere, including the slow movement and destructive impact of Hurricane Harvey in August 2017.
