Cap cloud or cloud cap is a stratiform, orographic cloud that hovers above or over an isolated mountain peak, formed by the cooling and condensation of moist air forced up and over the peak and lenticularly shaped by horizontal upper level winds.
Cap or Cap Strength: It measures the ability of stable air aloft (a layer of relatively warm air) to inhibit low-level parcel ascent.
Cap - A layer of warm air, sometimes several thousand feet above the surface. A cap will suppress or delay the development of thunderstorms by preventing unstable air near the surface from rising past the cap.
Cap (or Capping Inversion) - A layer of relatively warm air aloft (usually several thousand feet above the ground) which suppresses or delays the development of thunderstorms.
Cap
Also called a capping inversion.
A layer of relatively warm air aloft (usually a few thousand metres above the ground) which suppresses or delays the development of thunderstorms.
CAP
Composed of a layer of warmer, dryer air aloft which may suppress or delay the development of thunderstorms.
cap"(Also called lid.) A region of negative buoyancy below an existing level of free convection (LFC) where energy must be supplied to the parcel to maintain its ascent.

(also called "Lid") A layer of relatively warm air aloft, usually several thousand feet above the ground, which suppresses or delays the development of thunderstorms.
CAP- Temperature inversion which prevents convection from occurring.
CAT- A category. Usually refers to a category of precipitation given by the forecast models. Also the Category of hurricane intensity.
CB- Cumulonimbus.
Cap cloud See Pileus cloud.
Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.035 percent (355 ppm) in a volume of air near sea level.
cap cloud (also called cloud cap)—A standing or stationary cap-like cloud crowning a mountain summit.
Cap (or lid) - A layer of warm air, several thousand feet above the surface, which suppresses or delays the development of thunderstorms.
Ice Cap Climate A climate that has no monthly means above freezing and supports no vegetative cover except in a few scattered high mountain areas.
Polar Cap Absorption (PCA)
In solar-terrestrial terms, an anomalous condition of the polar ionosphere whereby HF and VHF (3 - 300 MHz) radiowaves are absorbed, and LF and VLF (3 - 300 kHz) radiowaves are reflected at lower altitudes than normal.
Cap cloud - one that sits still over a mountain
Chinook arch - Altostratus clouds downwind of a mountain range. Visible gap between overhead sheet and upwind horizon, when viewed from the ground below.
CAP - A dry and warmer air layer at mid altitudes that prevents any convection from rising above that region.
The cap is an important ingredient in most severe thunderstorm episodes, as it serves to separate warm, moist air below and cooler, drier air above.
When this cap weakens or moves, explosive development follows.
In the North America, supercells usually show up on Doppler radar as starting at a point or hook shape on the southwestern side, fanning out to the northeast.
Ensure that the cap on the bottle is screwed on tightly so that no water escapes when shaken.
Ask the students to carry out the activity from the worksheet then go over their results at the end of the class.
Questions and solutions ...
Tablecloth, Sansan, Cap Cloud, Crest Cloud, or Banner Cloud These are either local or generic names for the same cloud form. "Crest," " cap," or "banner" is used to describe the standing cloud that forms across the peak of a mountain ridge.
lid - (Also known as cap, capping inversion, capping layer.) A thin layer with enhanced static stability separating a layer below possessing large convective available potential energy from a layer above with lower static stability.
zones of increasing temperature with height are inversions (i.e. the inverse of the average state), and are very important for both synoptic/mesoscale meteorology (e.g. fog/stratus formation/dispersal), and pollution dispersion studies, as they cap ...
During the months of January through March it extends upward into the stratosphere where it modulates in the strength of the westerly vortex that encircles the Arctic polar cap region.
