DOOP Star ship commanded by the eternally incompetent Zapp Brannigan
From the TV series Futurama. The Nimbus is the flagship of the DOOP army.
If the rotation is violent and in contact with the ground, the vortex is a tornado. Funnel clouds can occur through a variety of processes in association with convection. For example, small funnel clouds are infrequently seen extending from small, dissipating cumulus clouds in environments with significant vertical wind shear in the cloud-bearing layer.
An accessory cloud veil of great horizontal extent draped over or penetrated by cumuliform clouds. Velum occurs with cumulus and cumulonimbus.
They get their anvil shape from the fact that the rising air in thunderstorms expands and spreads out as the air bumps up against the bottom of the stratosphere.
Latin for anvil. Also called anvil, anvil cloud, thunderhead. A supplementary cloud feature peculiar to cumulonimbus capillatus; the spreading of the upper portion of cumulonimbus when this part takes the form of an anvil with a fibrous or smooth aspect.
Pileus (the cap, hood or scarf) is formed as a moist layer locally lifted due to rising cloud below.
Capillatus come from the Latin for hair. Storm clouds. A cumulonimbus capillatus cloud is massive in every measure. It's the only cloud which can extend from almost ground level up to the tropopause. This is the tropical monster giving monsoon rains, rain showers, hail and wind.
An overshooting top or dome is a protrusion of the updraft extending above the anvil level. Generally the larger and the higher one is the more intense the updraft producing it is.
They can exist as individual towers or form a line of towers called a squall line. Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 39,000 feet (12,000 meters) or higher. Associated with powerful thunderstorms known as supercells.
Can occur at lower or mid levels of a tower. They may indicate the strength of the inflow of moist air into the storm, and, hence, its potential severity.
Also called cap cloud, scarf cloud. An accessory cloud of small horizontal extent, often cirriform, in the form of a cap, hood, or scarf, which occurs above or attached to the top of a cumulus or cumulonimbus (less often stratocumulus) cloud that often pierces it. Sometimes several pileus clouds are observed above each other. Pileus is formed as a moist layer locally lifted due to rising cloud below.
Cumulonimbus calvus is characterized by distinctive (between other types of cumulonimbus cloud) rounded shape and relatively sharp edges of its top area, unlike cumulonimbus incus or cumulonimbus capillatus, which have cirriform tops.
Usually associated with gusty winds, heavy rain, and sometimes hail and tornadoes.
Pouch-like protrusions that hang from under an anvil
They form due to turbulent air movement. Fractonimbus exist only under precipitation clouds (such as nimbostratus, altostratus or cumulonimbus) and don't bring precipitation themselves. Fractonimbus can with time completely merge with overlying nimbostratus clouds.
