Calm: A condition when no air motion is detected.
Cap or Cap Strength: It measures the ability of stable air aloft (a layer of relatively warm air) to inhibit low-level parcel ascent.
calm - 1. The absence of apparent motion of the air. In the Beaufort wind scale, this condition is reported when smoke is observed to rise vertically, or the surface of the sea is smooth and mirrorlike.
CALM
Atmospheric conditions devoid of wind or any other air motion. In oceanic terms, it is the apparent absence of motion of the water surface when there is no wind or swell.

calm: when the air conditions have no movement or wind.
calorie: the amount of heat required to raise the temperature of one gram of water one degree Celsius.
ceilometer: an instrument used to measure cloud height.
Calm- the absence of apparent motion in the air.
Ceiling- the height of the lowest layer of broken and overcast clouds.
Celsius- a temperature scale in which zero is the freezing point of water and one hundred is the boiling point.
CALM - the absence of apparent motion in the air.
CAP - Temperature inversion which prevents convection from occurring.
CAT - A category. Usually refers to a category of precipitation given by the forecast models.
Calm
Absence of air motion or wind with a speed of less than 1 knot.
Carbon Dioxide
A gas present in the atmosphere to the extent of more than 0.03% by volume and playing an important role in the greenhouse effect.
calm—The absence of wind or of apparent motion of the air.
cap cloud (also called cloud cap)—A standing or stationary cap-like cloud crowning a mountain summit.
Calm- the absence of apparent motion in the air.
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.
Calm:No wind.
Calorie:The amount of heat required to raise 1 gram of water 1 Deg. C. A gram is about the size of a small paper clip.
Calm: No wind: No movement of air:
CAT: "Clear Air Turbulence" turbulence that occurs in clear air with no clouds..
Calm
Beaufort force 0. Wind speed less than 1 knot. Sea like a mirror.

On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
Calm Wind with a speed below 1 knot (1 mph); Beaufort scale number 0.
Windy or cloudy conditions will tend to produce slow temperature recovery, while clear, calm weather can cause rapid recovery.
It occurs at very low temperatures, and usually in clear, calm weather in high latitudes. The sun is usually visible and may cause halo phenomena.
Sometimes in Melbourne, the night before the onset of severe fire weather conditions is calm and mild, ...
Old Wives' summer"A period of calm, clear weather, with cold nights and misty mornings but fine warm days, which sets in over central Europe toward the end of September; comparable to Indian summer.
The Ethiopian capital Addis Abeba remained calm, with few shops open and no taxis operating. (BBC)
The Old Bailey in the U.K. sentences five white supremacists to jail for 15 years for creating and distributing race hate material. (BBC) ...
The resultant waves much the same as waves propagating in a calm pond after a rock is tossed.
Horse latitudes Areas of calm winds associated with subtropical anticyclones; near 30 degrees latitude in both hemispheres.
Hot-wire anemometer An instrument that measures wind speed based on the rate of heat loss to air flowing by a sensor.
Beaufort Force 0 - Wind less than 1 kt, Calm, Sea surface smooth and mirror-like. Smoke rises vertically.
Beaufort Force 1 - Wind 1-3 kt, Light Air, Scaly ripples, no foam crests. Smoke drift indicates wind direction, still wind vanes.
Eye- The roughly circular area of relatively calm weather at the center of a hurricane.
Fahrenheit Temperature Scale- A temperature scale that uses 32 degrees as the melting point of ice and 212 degrees as the boiling point of water.
Weather - State of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness. Also, weather is the meteorological day-to-day variations of the atmosphere and their effects on life and human activity.
Laurence This is a term used in meteorology to describe a shimmering or terrestrial scintillation observed over a hot surface on a calm, cloudless summer day.
Eye
The relatively calm center of the tropical cyclone that is more than one half surrounded by wall cloud.
Horse Latitude - A belt of calm or light variable winds and subsiding air located near the center of the subtropical high. (30 degrees North Lattitude) ...
DOLDRUMS Located between 30 degrees North and 30 degrees South latitudes in the vicinity of the equator, this area typically has calm or light and variable winds. Also a nautical term for the equatorial trough.
Eye - the roughly circular area of a tropical cyclone marked by only light winds or completely calm with no precipitation
Eye Wall- the collection of thunderstorms which generally surround the eye of a hurricane ...
(this quoted directly from the Meteorological Glossary, HMSO): " A warm, calm spell of weather occurring in the autumn, especially in October and November.
Eye: The low pressure center of a tropical cyclone. Winds are normally calm and sometimes the sky clears. ...
Ice Fog - Fog composed of ice crystals instead of water droplets. Ice fog forms when clear and calm conditions prevail in extremely cold arctic air.
One well known characteristic of a hurricane is it's eye, which is generally about 5 to 25 miles in diameter and in which are present calm conditions, with clear skies and light winds.
Wind chill equivalent temperature A theoretical air temperature at which the heat loss from exposed skin under calm conditions is equivalent to the heat loss at the actual air temperature and under the actual wind speeds.
Ice Fog: Fog composed of minute ice particles that occurs in very low temperatures (typically minus 30 °C/ minus 22°F or below) under clear, calm conditions in the polar latitudes.
The length of each line is proportional to the frequency of wind from that direction, and the frequency of calm conditions is entered in the center.
The eye remains calm with light winds and often a clear sky. Hurricanes may move as fast as 50 mph, and can become incredibly destructive when they hit land.
an effect similar to friction, but the momentum transfer may accelerate air as well as retard it. The top of the stable layer under a temperature inversion is one example of this. Beneath the inversion, the air is stable and the wind may be calm, ...
