cloud droplet"Often used interchangeably with cloud drop. When used together, a cloud droplet is considered smaller and falling more slowly than a cloud drop; a cloud drop may grow by coalescence with cloud droplets.
Cloud Droplets: Small drops of liquid water, approximately 4 to 100 micrometres in diameter, that remain suspended in the air. They are smaller in size than either drizzle or rain drops. An aggregate of cloud droplets forms a visible cloud.
Cloud droplets are so small that you need a magnifying glass to see them.
Most people think that
raindrops look like tear drops.
Like the one below.
Cloud Droplets Cloud droplets are so small you could but more than a million in a teaspoon. At the center of each droplet of water
or ice is even a smaller speck of: Dust: Dirt: Smoke: Salt: Soot: called "Nuclei".
As the cloud droplets grow in size, they begin to fall back to the earth as precipitation.
ACID RAIN: Cloud droplets combining with gaseous pollutants, such as oxides of sulfur and nitrogen, to make falling rain or snow acidic.
AIR MASS: A widespread body of air with consistent temperature and moisture characteristics.
Supercooled cloud droplets Liquid cloud droplets observed at temperatures below freezing.
Superior mirage See Mirage.
Supersaturated air A condition that occurs in the atmosphere when the relative humidity is greater than 100 percent.
Drop-size DistributionThe distribution of rain drops or cloud droplets of specified sizes.DroughtDrought is a deficiency of moisture that results in adverse impacts on people, animals, or vegetation over a sizeable area.
cloud condensation nucleusA particle, either liquid or solid, upon which water condenses to form cloud droplets.cloud coverThe amount of the sky obscured by clouds when observed at a particular location.
On Köhler curve plots of saturation relative humidity versus aerosol particle radius, equilibrium haze particles are to the left of the peak, while growing cloud droplets are to the right.
cloud formation: cloud-condensation nuclei, cloud droplets
For condensation to occur at the dew point water vapor needs a surface to condense on.
Coffision-Coalescence Process - A theory of raindrop formation in warm clouds (above 0°C) in which large cloud droplets ('giants') confide and join together with smaller droplets to form a raindrop.
Subsidence will generally evaporate most cloud droplets after less than 500 meters, due to adiabatic heating. Thus, high pressure typically brings clear skies.
Coalescence The merging of cloud droplets into a single larger droplet.
Cold fog See Supercooled cloud.
Cold front The leading edge of a cold air mass.
The growth of liquid cloud droplets grow by collision.
Col
On the weather map an area between two highs and two lows.
Water-based particles present in the atmosphere, usually falling, such as rain drops, cloud droplets, graupel or hail, snow and sleet.

Air turbulence and hot engine exhaust often cause cloud droplets to evaporate along the path of the craft, forming a distrail. This is the opposite of a CONTRAIL, where condensation is encouraged by the aircraft, and occurs at higher altitudes.
Condensation
The physical process by which water vapor is transformed into dew, fog, or cloud droplets.
Continental Air
Mass of air which remains over a continent for several days and which, therefore, has a fairly low moisture content.
Corona Colored rings about the moon or sun; due to diffraction of light by spherical cloud droplets.
Cumuliform clouds Clouds that exhibit significant vertical development; often produced by updrafts in convection currents.
Cloud Condensation Nuclei- small particles in the air on which water vapor condenses and forms cloud droplets.
Cloudy- the state of the sky when 7/10ths or more of the sky is covered by clouds.
Small particles in the air on which water vapor condenses and forms cloud droplets.
Cloud Layer
An array of clouds whose bases are at approximately the same level.
1. Cumulus cloud - a cauliflower shaped cloud with a flat base and sharp edges. Tufts are rising columns of air condensing. As the cloud and cloud droplets grow in size, the base will begin to gray.
the interaction of a saturated stable air layer, usually an inversion, and a pattern of vertical wind shear, which results in somewhat evenly spaced zones of updraft (where cloud tops crest in a wave-like pattern) and subsidence (where cloud droplets ...
It is used for the measurement of quantities relating to the size distribution of cloud droplets. Rotation anemometer A type of anemometer in which the rotation of an element serves to measure the wind.
