types:
cloud
a visible mass of water or ice particles suspended at a considerable altitude
air hole,
air pocket,
pocket
a local region of low pressure or descending air that causes a plane to lose height suddenly
aurora
an atmospheric phenomenon consisting of bands of light caused by charged solar particles following the earth's magnetic lines of force
front
(meteorology) the atmospheric phenomenon created at the boundary between two different air masses
greenhouse effect,
greenhouse warming
warming that results when solar radiation is trapped by the atmosphere; caused by atmospheric gases that allow sunshine to pass through but absorb heat that is radiated back from the warmed surface of the earth
inversion
the layer of air near the earth is cooler than an overlying layer
storm,
violent storm
a violent weather condition with winds 64-72 knots (11 on the Beaufort scale) and precipitation and thunder and lightning
midnight sun
the sun visible at midnight (inside the Arctic or Antarctic Circles)
halo
a circle of light around the sun or moon
sunrise
atmospheric phenomena accompanying the daily appearance of the sun
sunset
atmospheric phenomena accompanying the daily disappearance of the sun
afterglow
a glow sometimes seen in the sky after sunset
cirrus,
cirrus cloud
a wispy white cloud (usually of fine ice crystals) at a high altitude (4 to 8 miles)
condensation trail,
contrail
an artificial cloud created by an aircraft; caused either by condensation due to the reduction in air pressure above the wing surface or by water vapor in the engine exhaust
storm cloud
a heavy dark cloud presaging rain or a storm
sweat
condensation of moisture on a cold surface
firestorm
a storm in which violent winds are drawn into the column of hot air rising over a severely bombed area
warm front
the front of an advancing mass of warmer air
occluded front,
occlusion
(meteorology) a composite front when colder air surrounds a mass of warm air and forces it aloft
elves
an acronym for emissions of light and very low frequency perturbations due to electromagnetic pulse sources; extremely bright extremely short (less than a msec) electrical flashes forming a huge ring (up to 400 km diameter) in the ionosphere
blue jet,
jet,
reverse lightning
atmospheric discharges (lasting 10 msec) bursting from the tops of giant storm clouds in blue cones that widen as they flash upward
lightning
abrupt electric discharge from cloud to cloud or from cloud to earth accompanied by the emission of light
red sprites,
sprites
atmospheric electricity (lasting 10 msec) appearing as globular flashes of red (pink to blood-red) light rising to heights of 60 miles (sometimes seen together with elves)
downfall,
precipitation
the falling to earth of any form of water (rain or snow or hail or sleet or mist)
wave
a persistent and widespread unusual weather condition (especially of unusual temperatures)
elements
violent or severe weather (viewed as caused by the action of the four elements)
windstorm
a storm consisting of violent winds
dew
water that has condensed on a cool surface overnight from water vapor in the air
