An anvil cloud isn’t a stand-alone cloud, but more of a feature that forms at the top of a cumulonimbus cloud.  The anvil top of a cumulonimbus cloud is actually caused by it hitting the top of the stratosphere — the second layer of the atmosphere. Since this layer acts as a “cap” to convection (the cooler temperatures at its top discourage thunderstorms), the tops of storm clouds have nowhere to go but outward. Strong winds high up fan this cloud moisture (so high up that it takes the form of ice particles) out over great distances, which is why anvils can extend outward for hundreds of miles…

Cumulonimbus clouds are thunderstorm clouds. They develop from convection — the transport of heat and moisture upward into the atmosphere. But, whereas other clouds form when air currents rise several thousand feet and then condense where those currents stop, the convective air currents that create cumulonimbus are so powerful, their air rises tens of thousands of feet, condensing rapidly, and often while still journeying upward. The result is a cloud tower with bulging upper portions (that look something like cauliflower).  If you see a cumulonimbus, you can be sure there’s a nearby threat of severe weather, including bursts of rainfall, hail, and possibly even tornadoes. Generally, the taller the cumulonimbus cloud, the more…
