Formation of a mushroom cloud. Depicts the drawing up of cool air into the hot cloud via the stem, and inside the cloud is a toroidal circulation of hot gases with an updraft through the center of the toroid. Outside of the center of the cloud, the gas has هتا. substantially and looks like a regular cloud.
A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke, and usually condensed water vapour resulting from a large explosion. The effect is most commonly associated with a nuclear explosion , but any sufficiently energetic detonation or deflagration will produce a similar effect.
The following table shows the cloud varieties arranged across the top of the chart from left to right in approximate descending order of frequency of appearance. The genus types and some sub-types associated with each variety are sorted in the left column from top to bottom in approximate descending order of average overall altitude range.
Nancy Baker Cahill's augmented reality public art work, which launches on Monday of Frieze Week, depicts a mushroom cloud — 'the ultimate symbol of human-caused cataclysm.'
English: For decades this image was commonly misidentified as the mushroom cloud of the Little Boy bomb that formed around 8:15 AM local time. However due to its greater height and the wholly different time of day, it is a pyrocumulus* cloud that occurs frequently over firestorms.
The mushroom cloud was about 67 km (42 mi) high [48] (nearly eight times the height of Mount Everest), which meant that the cloud was above the stratosphere and well inside the mesosphere when it peaked. The cap of the mushroom cloud had a peak width of 95 km (59 mi) and its base was 40 km (25 mi) wide. [49] A Soviet cameraman said:

A pileus (/ ˈ p aɪ l i ə s /; Latin for 'cap'), also called scarf cloud or cap cloud, is a small, horizontal, lenticular cloud appearing above a cumulus or cumulonimbus cloud. Pileus clouds are often short-lived, appearing for typically only a few minutes, [ 1 ] with the main cloud beneath them rising through convection to absorb them.
