Landspout; Cumulonimbus calvus clouds can, on rare occasions, produce a unique type of tornado known as a landspout. Landspouts are formed when strong ground level rotation is caught in the updraft of the storm, pulling it upwards and connecting it to the clouds above resulting in the rotation becoming a true tornado.
A cumulonimbus incus is a mature thunderstorm cloud generating many dangerous elements. Lightning: this storm cloud is capable of producing bursts of cloud-to-ground lightning. Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft).
A cumulonimbus capillatus is a cumulonimbus cloud with dense cirrus clouds above it, making the cloud top appear to contain hair-like structures. The name comes from the Latin word capillatus, meaning "with hair". [1] It is an intermediate stage between cumulonimbus calvus and cumulonimbus incus.
Indicates that the air below the cloud is dry; can also signify the downdraft region of a storm. Wall clouds. A supercell forms and a wall cloud pushes north of Beardstown, Ill. Friday, March 31 ...
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.
A shelf cloud is a low, horizontal, wedge-shaped arcus cloud attached to the base of the parent cloud, which is usually a thunderstorm cumulonimbus, but could form on any type of convective clouds. Rising air motion can often be seen in the leading (outer) part of the shelf cloud, while the underside can often appear as turbulent and wind-torn.
Outbursts of Canadian wildfire smoke have filled the sky over the eastern United States in recent weeks, but a new airborne danger from a different source has reached another part of the country.
Cloud microphysics are the physical processes that describe the growth, decay, and fallout of precipitation particles. In terms of models, cloud microphysics occur on a scale smaller than the grid-scale of the model and have to be parameterized. [2] Hurricane track forecasts have been getting better in recent years.
