A cumulonimbus incus (from Latin incus 'anvil'), also called an anvil cloud, is a cumulonimbus cloud that has reached the level of stratospheric stability and has formed the characteristic flat, anvil -shaped top. [1] It signifies a thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage. [2]
LP supercells rarely spawn tornadoes, and those that form tend to be weak, small, and high-based tornadoes, but strong tornadoes have been observed. These storms, although generating lesser precipitation amounts and producing smaller precipitation cores, can generate huge hail.
Stanford scientists solve mystery of icy plumes that may foretell deadly supercell storms. The most devastating tornadoes are often preceded by a cloudy plume of ice and water vapor billowing ...
Well-developed cumulonimbus clouds are characterized by a flat, anvil shaped top (anvil dome), caused by wind shear or inversion at the equilibrium level near the tropopause. The shelf of the anvil may precede the main cloud's vertical component for many kilometres (miles), and be accompanied by lightning.
1 lis 2023 · Most destructive tornadoes are spawned by supercell thunderstorms—giants that typically have a very tall cloud that widens into an anvil shape at the top. Supercells are characterized by a...
3 lip 2019 · Produced when a rotating column of air condenses, funnel clouds are the visible part of tornadoes that extend downward from the parent thunderstorm cloud. But remember, not until the funnel reaches the ground or "touches down" is it called a tornado.
9 lip 2024 · Specifically, we emphasize the importance of the low-level wind shear and mesocyclone for tornado potential, the organization and interaction of relatively small-scale pretornadic vertical vorticity maxima, and the transition to a tornado-characteristic flow.
