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.
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.
What different clouds mean. Clouds are more than just picturesque features of the sky; they are critical indicators of the weather to come. Understanding the various types of clouds can provide ...
High clouds having the traditional "mare's tail" appearance. These clouds are long, fibrous, and curved, with no tufts or curls at the ends. Cirrus uncinus (V-2) Filaments with up-turned hooks or curls. Cirrus spissatus (V-3) Dense and opaque or mostly opaque patches. Cirrus castellanus (V-4) A series of dense lumps, or "towers", connected by a ...

Clouds form as relatively warmer air, carrying moisture, rises within cooler air. The moist air rises, and, as it does so, it cools and some of the water vapor in that rising air condenses . [ 10 ] When the moisture condenses, it releases energy known as latent heat of condensation, which allows the rising packet of air to cool less than the ...
Due to their larger density, these hailstones become heavy enough to overcome the density of the cloud and fall towards the ground. The downdrafts in cumulonimbus clouds can also cause increases in the speed of the falling hailstones. The term hailstorm is usually used to describe the existence of significant quantities or size of hailstones.
