Clouds are made up of ice crystals and droplets of water. These form when water evaporates from bodies of water, such as the oceans. Once water reaches higher altitudes in the atmosphere, it becomes liquid and solid.Know More
Heat from the sun causes water to evaporate. Once the evaporated water, called water vapor, reaches higher altitudes where temperatures are cooler, it becomes liquid water again. At even higher altitudes, the air becomes colder, and ice crystals form instead of liquid water. Clouds form when the water droplets or ice crystals become large enough to be seen.
Droplets and ice crystals move and bump into one another, forming larger water droplets and ice crystals. When these droplets and crystals become heavy enough, they fall to the ground as precipitation.Learn more about Clouds
According to Met Office, clouds form when water vapor in the air condenses into tiny drops of water or ice crystals that then settle on dust particles in the atmosphere. Condensation happens when the air is saturated and cannot hold any more water vapor; this can occur when the amount of water in the air increases or when the air is cooled to its dew point.Full Answer >
Nimbus clouds are cloud types that can indicate some type of precipitation. The word "nimbus" comes from the Latin language and stands for rain. There are two different types of nimbus clouds that indicate the type of precipitation.Full Answer >
Clouds move due to wind currents that carry them through the lower levels of Earth's atmosphere. Even if there is no wind felt at ground level, wind constantly blows through the atmosphere carrying clouds, air particles and dust with it.Full Answer >
Clouds can be measured by the height and appearance of the shape to determine weather conditions. Scientists often use a device, such as the micropulse lidar or infrared thermometer to determine a cloud's altitude and height.Full Answer >
