Spray (PY) An ensemble of water droplets torn by the wind from the surface of the of an extensive body of water, generally from crests of waves, and carried a short distance into the air.

An ensemble of water droplets torn by the wind from an extensive body of water, generally from the crests of waves, and carried up into the air in such quantities that it reduces the horizontal visibility.

Freezing Spray: An accumulation of supercooled water droplets on a vessel or object which are below the freezing point of water. It usually develops in areas with winds of at least 25 knots.
A specific aerial spray dispersion model. The acronym comes from the names of the sponsor and developers (Forest Service, Cramer, Barry, Grim).

Blowing sprayWater droplets torn by the wind from a body of water, generally from the crests of waves, and carried up into the air in such quantities that they reduce the reported horizontal visibility to less than seven statute miles.
Marine rainbow A rainbow seen in the spray of the ocean. It is optically the same phenomenon as the ordinary rainbow. Marine thermometer See sea-water thermometer, reversing thermometer.
It is visible when the sun is shining through air containing water spray or raindrops, which occurs during or immediately after a rain shower. The bow is always observed in the opposite side of the sky from the sun.
Freezing SprayAn accumulation of freezing water droplets on a vessel caused by some appropriate combination of cold water, wind, cold air temperature, and vessel movement.
This is also called the zone of aerationVALDRIFTAn air pollution transport and diffusion model developed to determine pesticide drift from aerial spraying operations in valleys.
Heavy Freezing SprayAn accumulation of freezing water droplets on a vessel at a rate of 2 cm per hour or greater caused by some appropriate combination of cold water, wind, cold air temperature, and vessel movement.
CFCs include refrigerants, propellants for spray cans (this usage is banned in the U.S., although some other countries permit it) and for blowing plastic-foam insulation, styrofoam packaging, and solvents for cleaning electronic circuit boards.
Rain: Rapidly forming puddles, down pipes flowing freely, some spray visible over hard surface.
Drizzle: Window and road surfaces streaming with moisture. Visibility generally between 400 and 1000 m.

ocean spray which obscures the visibility below 7 miles.
Occluded Front: A condition in the atmosphere when an air mass gets trapped between to colder air masses and is forced aloft.
Occlusion: To Close or come together.
Strong winds up to 60 mph or greater may lead to high swells and destructive coastline waves and sea spray. Greek fishermen are especially mindful of watching for and reporting on bourini squalls as they move across the region.
Barber A strong wind carrying damp snow or sleet and spray that freezes upon contact with objects, especially the beard and hair.
Bayamo A violent wind blowing from the land on the south coast of Cuba, especially near the Bight of Bayamo.
Beaufort force 12. Sustained wind speed greater than 63 knots. The air is filled with foam and spray; sea completely white with driving spray; visibility very seriously affected.

CONFORMAL COATING: A protective coating applied to circuits usually by spray deposition.
CROSSWIND: A wind blowing perpendicular to the course of a moving object. Often used when referring to winds affecting ballistics.
In the atmosphere water vapor starts to condense on microscopic particles suspended in the air: dust, soot, volcanic ash, salt spray, etc. These are called cloud-condensation-nuclei.
CFC (Chlorofluorocarbons)- Chlorine compounds formerly used in air conditioners, refrigerators, and spray cans; also called CFC's.
Climate-The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area.
Rainbows can often be seen in the spray and mist coming from larger waterfalls, as here at Takakkaw Falls, Canada.
Most common with clouds and sunlight, or spray droplets from waterfalls. Size of the circle is affected by the size of the refracting drops or particles, as well as the distance to them. A RAINBOW is a type of halo. Also may be called a GLORY.
Rainbow - an arc of concentric colored bands, arranged from red to blue, which may be seen on a "sheet" of water drops (rain, fog, spray) ...
Dust is due to many natural and artificial sources, for example, volcanic eruptions, salt spray from the seas, blowing solid particles, plant pollen, bacteria, and smoke and ashes from forest fires and industrial combustion processes.
Rainbows can be seen when the sun is shining and the air contains water spray or raindrops. This condition occurs frequently during or immediately following showers. Rainbows are always observed in the portion of the sky opposite the sun.
