WebOne of the most familiar roles of clouds, however, is in producing precipitation. Clouds are made up of water droplets, ice particles, or a mixture of both, suspended in air. These particles are between 20 and 50 ?m (0.0008–0.002 in.) in diameter. Cloud particles do not form in empty space. They need a tiny center of solid matter to grow around. Stratus clouds form when weak vertical currents lift a layer of air off the ground and it depressurizes, following the lapse rate. This causes the relative humidity to increase due to the adiabatic cooling. This occurs in environments where atmospheric stability is abundant. Meer weergeven Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals. More specifically, the term stratus is … Meer weergeven Species Stratus nebulosus clouds appear as a featureless or nebulous veil or layer of stratus … Meer weergeven Cirrostratus clouds Cirrostratus clouds, a very high ice-crystal form of stratiform clouds, can appear as a milky sheen in the sky or as a striated sheet. They are sometimes similar to altostratus and are distinguishable from the latter … Meer weergeven Stratus clouds look like featureless gray to white sheets of cloud. They can be composed of water droplets, supercooled water droplets, or ice crystals depending upon the ambient temperature. Meer weergeven A stratus cloud can form from stratocumulus spreading out under an inversion, indicating a continuation of prolonged cloudy weather with drizzle for several hours and then an improvement as it breaks into stratocumulus.

What are clouds? - Met Office
WebHowever, the reason behind clouds moving in the opposite direction may be the surface friction slowing the wind. This may eventually cause a shift in the direction of the current and near the surface. So, the cloud movement may differ from the wind direction during that point. You may also notice that the clouds close to the ground are moving ... Web6 apr. 2024 · Mid-Level Clouds – Mid-level clouds can be found between about 7,000 feet and 23,000 feet (2,000 m to 7,000 m) above the ground. High-Level Clouds – The … bir alphalist report
Stratus Cloud Facts & Formation What Is a Stratus Cloud?
WebClouds Form in Different Ways. Some clouds form as air warms up near the Earth's surface and rises. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. Webformation. Stratus clouds form when a sheet of warm, moist air lifts off the ground and depressurizes, following the lapse rate. Stratus clouds look like featureless gray to white sheets of cloud. Forecast, relation to other clouds, or subforms are a few more items to look into. So, what is a stratiform cloud? WebThese are flat, grey, featureless layers which often sit low to the ground, hiding the clouds above. Sometimes these can produce a light drizzle. Fog is simply a stratus cloud which has come down to surface level, so when you walk through fog, you are actually walking through a cloud. biral typ a12-1
