This phenomenon all comes down to a little something called the Rayleigh-Taylor instability, and by extension, convection. I’ll begin with the somewhat longer, but less geeky explanation before descending once again into extreme nerdery. It all starts with an explosion that creates a Pyrocumulus Cloud. As the ball rises, it will leave behind air that is heated, creating a chimney-like effect that draws in any smoke and gases on the outer edge of the chimney- convection in action! The perception that the mushroom cap is curling down and around the stipe is primarily a result of the differences in temperature at the center of the cap and its outside. Once that cloud reaches a certain point in our atmosphere, where the density of the gas cloud is the same as the density of the surrounding air, it will spread out, creating a nice cap. This brings me to the shorter, yet more geeky answer. If you liked this article, you might also enjoy:
