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
condensate, condensation
atmospheric moisture that has condensed because of cold
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

electrical discharges in the atmosphere
midnight sun
the sun visible at midnight (inside the Arctic or Antarctic Circles)
halo
a circle of light around the sun or moon

a transient shower of meteors when a meteor swarm enters the earth's atmosphere
sunrise
atmospheric phenomena accompanying the daily appearance of the sun
sunset
atmospheric phenomena accompanying the daily disappearance of the sun

warm front
the front of an advancing mass of warmer air
cold front, polar front
the front of an advancing mass of colder air
occluded front, occlusion
(meteorology) a composite front when colder air surrounds a mass of warm air and forces it aloft

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

thaw, thawing, warming
warm weather following a freeze; snow and ice melt
parhelic circle, parhelic ring, solar halo
