This optical phenomenon occurs because rays of light are strongly bent when they pass through air layers of different temperatures in a steep thermal inversion where an atmospheric duct has formed. [39] A thermal inversion is an atmospheric condition where warmer air exists in a well-defined layer above a layer of significantly cooler air.
Atmospheric optical phenomena include: Afterglow; Airglow; Alexander's band, the dark region between the two bows of a double rainbow. Alpenglow; Anthelion; Anticrepuscular rays; Aurora (northern and southern lights, aurora borealis and aurora australis) Belt of Venus; Brocken Spectre; Circumhorizontal arc; Circumzenithal arc; Cloud iridescence ...
Atmospheric dynamics is the study of motion systems of meteorological importance, integrating observations at multiple locations and times and theories. Common topics studied include diverse phenomena such as thunderstorms, tornadoes, gravity waves, tropical cyclones, extratropical cyclones, jet streams, and global
The global-scale movement of air masses within the Earth's atmosphere. All meteorological phenomena are consequences of the atmospheric circulation, which manifests as a network of both latitudinal and longitudinal "cells" of convective activity; together with ocean circulation, these cells are the primary means by which thermal energy from the ...
An aurora is a natural phenomenon. A natural phenomenon is an observable event which is not man-made. Examples include: sunrise , weather , fog , thunder , tornadoes ; biological processes , decomposition , germination ; physical processes , wave propagation , erosion ; tidal flow , and natural disasters such as electromagnetic pulses ...
Mesoscale meteorology is the study of atmospheric phenomena that has horizontal scales ranging from 1 km to 1000 km and a vertical scale that starts at the Earth's surface and includes the atmospheric boundary layer, troposphere, tropopause, and the lower section of the stratosphere. Mesoscale timescales last from less than a day to multiple weeks.
Atmospheric Rivers. This headline-making phenomenon has been drenching parts of the West Coast lately — but what, exactly, is an atmospheric river?
Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena. [ 1 ] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates.
