Atmospheric wave: Difference between revisions

An '''atmospheric wave''' is a periodic disturbance in the fields of [[atmospheric]] variables (like [[Atmospheric pressure#Surface pressure|surface pressure]] or [[geopotential height]], [[temperature]], or [[wind velocity]]) which may either propagate (''[[traveling wave]]'') or notbe stationary (''[[standing wave]]''). Atmospheric waves range in [[Three-dimensional space|spatial]] and [[Time|temporal]] scale from large-scale planetary waves ([[Rossby wave]]s) to minute [[sound wave]]s. Atmospheric waves with periods which are [[harmonics]] of 1 [[solar day]] (e.g. 24 hours, 12 hours, 8 hours... etc.) are known as [[atmospheric tide]]s.
