Debris cloud (informal term) – rotating "cloud" of debris found at base of tornado. Funnel cloud (WMO supplementary feature tuba) – rotating funnel of cloud hanging from under Cb, not making contact with ground. Hail fog (informal term) – a shallow surface layer of fog that sometimes forms in vicinity of deep hail accumulation, can be ...
Attached to many wall clouds, especially in moist environments, is a cauda [1] (tail cloud), a tail-like band of cloud extending from the wall cloud toward the precipitation core. [6] It can be thought of as an extension of the wall cloud in that the tail cloud is connected to the wall cloud and condensation forms for a similar reason.
Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes. Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.
Can indicate the presence of a mesocyclone and potentially a tornado. Scud clouds. Low, ragged clouds that appear beneath the main cloud base. Formed from moist air lifted by outflow winds from a ...
Cloud seeding, a fascinating weather modification technique, involves introducing substances like silver iodide, salt, or dry ice into clouds to encourage the formation of raindrops or snowflakes.
These aerial photos and video shots show the extent of the devastation caused by the tornadoes that ripped through Kentucky communities. See the aerial photos, video of the devastating damage ...
Heavy rain: this cloud may drop several inches (centimetres) of rain in a short amount of time. This can cause flash flooding. Strong wind: gale-force winds from a downburst may occur under this cloud. Tornadoes: in severe cases (most commonly with supercells), it can produce tornadoes. They are not directly produced by cumulonimbus incus but ...
These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes, hazardous winds, and large hailstones. Cumulonimbus progress from overdeveloped cumulus congestus clouds and may further develop as part of a supercell .
