Regular ol’ cumulus and cumulonimbus clouds are beautiful on their own, but there are different formations and appendages that can make these clouds … Anvil - The spreading out (by strong winds) of the upper portion of the thunderstorm. The sunlit anvil tops of thunderstorms here are estimated to be in excess of 60,000 feet (18,300 m) where icy cirrus clouds form near the top of the troposphere. A cumulonimbus incus cloud, showing the characteristic anvil-top shape the cloud type displays, Learn how and when to remove this template message, Nitric acid and water polar stratospheric clouds, https://en.wikipedia.org/w/index.php?title=Cumulonimbus_incus&oldid=984092255, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 October 2020, at 03:36. The thunderstorm anvil is a common sight during the summer months here in Kentuckiana. Thunderstorm development requires an unstable atmosphere. 14.1). Two thunderstorm clouds with above-anvil plumes were observed in satellite imagery over northern Italy in the morning and afternoon of 6 July 2010. They are capable of producing severe storm conditions for a short amount of time. Cumulonimbus incus is a sub-form of Cumulonimbus capillatus. The anvil at the top of the cloud indicates where rising parcels become stable and begin to spread out horizontally. English: Anvil of a thundercloud over Columbia. As storm-producing cumulonimbus clouds hit the tropopause their tops flatten out, giving them an anvil-like appearance. The dissipating stage of the life cycle of a thunderstorm cell is characterized by. It signifies the thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage. This lateral spreading forms the cloud anvil at the top of the thunderstorm along the tropopause boundary. She specializes in climate and weather. In fact, shuttle​s are not only at risk from any lightning occurring within the anvil cloud itself, but it can also trigger more lightning to occur. What two atmospheric processes lead to the formation of the anvil … Cumulonimbus incus cloud formations are more popularly known as anvil clouds and are generally found in strong thunderstorms. In this study the radiative impact of three separate cirrus anvil systems that occurred during the Maritime Continent Thunderstorm Experiment is investigated. Do not launch if the flight path will carry the vehicle... Named for their likeness to an iron anvil, anvil clouds are the icy upper portions of cumulonimbus thunderstorm clouds that are caused by a rising of air in the lower portions of the atmosphere. The National Aeronautics and Space Administration (NASA's) Anvil Cloud Rule is a set of rules that keep space shuttles weather safe during severe thunderstorms. A cumulus cloud stops growing when it hits the warm stratosphere. Typical thunderstorms top out at the tropopause, the boundary between the troposphere — the lowest part of Earth’s atmosphere — and the stratosphere. The synoptic situation was favorable for the development of deep convection. When the space shuttle goes high into the atmosphere, the long plume from the exhaust gives a pathway through which lightning can flow. A cumulonimbus incus is a mature thunderstorm cloud generating many dangerous elements.
