A cumulonimbus incus (Latin incus, "anvil") is a cumulonimbus cloud which has reached the level of stratospheric stability and has formed the characteristic flat, anvil-top shape. Clouds form when the Dewpoint of Water is reached in the presence of Condensation nuclei in the Troposphere. Clouds form when the Dewpoint of Water is reached in the presence of Condensation nuclei in the Troposphere. A cloud is a visible mass of droplets or frozen crystals floating in the atmosphere above the surface of the Earth or another Planetary body Clouds form when the Dewpoint of Water is reached in the presence of Condensation nuclei in the Troposphere. Cumulonimbus (Cb is a type of Cloud that is tall dense and involved in Thunderstorms and other intense Weather. The tropopause is in the atmosphere between the Troposphere and the Stratosphere. It can cause a supercell and then a tornado. A supercell is a severe thunderstorm with a deep continuously rotating updraft (a Mesocyclone) A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus
