Fair Weather Cumulus Clouds puffy cotton balls floating in the sky
Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes.

 


fair - With respect to weather, generally descriptive of pleasant weather conditions, with due regard for location and time of year. It is subject to popular misinterpretation, for it is a purely subjective description.

Fair It is usually used at night to describe less than 3/8 opaque clouds, no precipitation, no extremes of visibility, temperature or winds. It describes generally pleasant weather conditions.

FAIR
This is a subjective description. Considered as pleasant weather conditions with regard to the time of year and the physical location.

It is usually used at night to describe less than 3/8 opaque clouds, no precipitation, no extremes of visibility, temperature or winds. It describes generally pleasant weather conditions.

FAIR: Less than 4/10 opaque cloud cover, no precipitation, and no extremes in temperature, visibility or winds.

Fair- describes weather in which there is less than 4/10ths of opaque cloud cover and no precipitation; and there is no extreme visibility, wind or temperature conditions.
Fall Wind- a strong, cold, downslope wind.

Fair-weather bias The observation that fair weather days outnumber stormy days almost everywhere.
Flash flood A sudden rise in river or stream levels causing flooding.

Fair Weather The word "fair" is derived from old Middle English usage and has many different meanings. It may be used as an adjective, adverb, verb, or noun.

Cumulus of fair weather
A cloud is a visible mass of condensation droplets or ice crystals suspended in the atmosphere above the surface of the Earth or another planetary body.

Occurs when prevailing wind direction is from the same direction as the elevated terrain and often produces fair weather conditions.

Weather stick Made of birch and attributed to northeast Native American tribes, the stick is said to rise indicating fair weather and to drop when inclement weather is approaching. The movement of the tip appears to track the relative humidity.

anabatic wind"In mountain meteorology, an upslope wind driven by heating (usually daytime insolation) at the slope surface under fair-weather conditions. The mechanism of the anabatic wind can be described as follows.

Fair weather cumulus do not show extensive "towers" or vertical development and do not produce precipitation. A cumulus may, however, be an early stage in the development of towering cumulus or cumulonimbus.

Dry microbursts may develop in an otherwise fair-weather pattern; visible signs may include a cumulus cloud or small Cb with a high base and high-level virga, or perhaps only an orphan anvil from a dying rain shower.

Cumulus humilus are cumulus clouds with little vertcal development. Cumulus mediocris show slightly more vertical development, but indicate fair weather, giving them the name fair weather cumulus.

One side of the Walker Circulation is associated with rising motion, clouds, and rain while the opposite side with sinking motion, generally fair weather and little or no rain.

5 inches; then 'Rain', 'Much Rain' and 'Stormy' at each half-inch on the lower side, and 'Fair', 'Set Fair' and 'Very Dry' on the high side.

Eye - A roughly circular area of relatively light winds and fair weather at the center of a hurricane.
Eye Wall - The doughnut-shaped area ofintensive cumulonimbus development and very strong winds that surrounds the eye of a hurricane.

High Pressure System - A whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies.

Each side of the coin has an equal chance of coming up, so it is a fair way to decide who will shoot first.

Cumulus Cloud:Puffy white fair weather clouds that result from rising air currents (Thermals).
Cut Off Low or High:Low or High pressure systems which are cutoff from the main west to east flow.
Cyclogenesis: The birth of a cyclone.

eye—The roughly circular area of calm or relatively light winds and comparatively fair weather at the center of a well-developed tropical cyclone. A wall cloud marks the outer boundary of the eye.

cumulus: a low cloud that develops from the bottom up. Appear white and puffy, with a cauliflower-like top. Small ones are associated with fair weather(cumulus humilis), but as they grow vertically, ...

High Pressure - An area of a relative pressure maximum that has diverging winds and rotates in the opposite direction as the earth. This is generally indicative of fair weather, ...

It has a flat base with a bulging upper part that often resembles cauliflower. Cumulus clouds of fair weather are called cumulus humilis. Those that exhibit much vertical growth are called cumulus congestur or towering cumulus.

A region of high pressure. Air flows outward and (on the northern hemisphere) clockwise around high pressure areas. A high is usually associated with fair weather. Also called "anticyclone".

HIGH PRESSURE - A region of high air pressure in the atmosphere. Commonly associated with fair weather. Strong high-pressure regions may cause strong outflow winds.

Anticyclone - An area of high pressure. Winds blow in a clockwise direction in the Northern Hemisphere and in a counter clockwise direction in the Southern Hemisphere. Fair weather is associated with an anticyclone.

Dust Devil - A small atmospheric vortex not associated with a thunderstorm, which is made visible by a rotating cloud of dust or debris (dust whirl). Dust devils form in response to surface heating during fair, hot weather.
