Hail in the tropics occurs mainly at higher elevations. [20] Hail growth becomes vanishingly small when air temperatures fall below −30 °C (−22 °F), as supercooled water droplets become rare at these temperatures. [19] Around thunderstorms, hail is most likely within the cloud at elevations above 20,000 ft (6,100 m).
A cumulonimbus cloud emitting green is a sign that it is a severe thunderstorm, [21] capable of heavy rain, hail, strong winds and possible tornadoes. The exact cause of green thunderstorms is still unknown, but it could be due to the combination of reddened sunlight passing through very optically thick clouds.
A tornado is a dangerous rotating column of air in contact with both the surface of the earth and the base of a cumulonimbus cloud (thundercloud), or a cumulus cloud in rare cases. Tornadoes come in many sizes but typically form a visible condensation funnel whose narrowest end reaches the earth and is surrounded by a cloud of debris and dust.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Frostbite in dogs is a serious condition. It occurs when the skin and underlying tissues are exposed to freezing or extremely cold temperatures for a prolonged period of time.
Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft). 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.
