are anvil clouds dangerous

While cumulonimbus clouds are dangerous, harboring heavy rains, extreme turbulence and wind, icing conditions, hail, lightning, and even tornadoes, the clouds themselves are easily identified by their towering shape and associated rainfall. Shading from anvils causes cool anomalies in the underlying sea surface temperature (SST) of up to 20.68C. An anvil cloud closely resembles a large mushroom in the sky. If enough moisture is present to condense and heat the cloud mass through several convective cycles, a tower can rise to altitudes of approximately 10 kilometers at high latitudes and to 20 kilometers in the tropics before encountering a region of the atmosphere known as the tropopause—the boundary between the troposphere and the stratosphere. It is necessary to understand these cloud formations, in order to be able to differentiate between them.
