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).
Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere.
Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
Develops from cumulus clouds and can reach great heights, often associated with thunderstorms. Indicates severe weather, such as thunderstorms, heavy rain, hail, and sometimes tornadoes. Mammatus ...
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.
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.
Unlike hail or sleet, graupel is soft and can be crushed easily in your hand, and is sometimes called "soft hail." It is also usually smaller than hail, with a diameter of around 0.08-0.2 inches.
A cumulonimbus cloud that appears to have a greenish or bluish tint is a sign that it contains extremely high amounts of water; hail or rain which scatter light in a way that gives the cloud a blue color.
