advection

the transference of heat energy in a horizontal stream of gas, esp of air

advection

[‚ad′vek·shən]
(meteorology)
The process of transport of an atmospheric property solely by the mass motion of the atmosphere.
(oceanography)
The process of transport of water, or of an aqueous property, solely by the mass motion of the oceans, most typically via horizontal currents.

advection

A method of heat transfer by horizontal movement of air or fluid. Unlike convection, where heat transfer takes place because of vertical movement, here the horizontal movement is the cause. When cold air comes into contact with warm ground or water, it heats up because of advection.

Taylor s hypothesis has recently undergone extensive scrutiny and several studies dispute the idea that turbulent eddies are advected at the mean speed of the flow, arguing that the advection speed depends on the frequency and wavenumber of the turbulent eddies [21] [22] [23], New light is being shed on this phenomenon, especially since the advent of spatial measurement techniques such as Particle-Image Velocimetry (PIV) in wind tunnels [24], direct numerical simulations of turbulent flows [22], [21] and the use of arrays of ultrasonic wind sensors [25] and LiDARs (15) [23] for field measurements in the atmospheric surface layer.
A retardation coefficient (R) is necessary to adjust the advection and diffusion terms to account for the fact that heat is stored and conducted through both the water and rock, but heat is only advected by the water (Bear 1972).
Early summer usually is dry, whereas intense localized thunderstorms are common in late summer, caused by the North American Monsoon (hereafter, monsoon) when moisture is advected from the Pacific Ocean and Gulf of California (Adams and Comrie, 1997).
This situation is most evident in Bahia Magdalena during periods of coastal upwelling, when cool oceanic water is advected into the Bay (Bakun and Nelson 1977; Lluch-Belda et al.

In the cross-flow design, the fluidized solids are advected through the reactor in a direction perpendicular to the fluidizing medium.
A "dilution factor" is applied to the maximum beam impact in order to account for the increasing amount of contaminant "loss" due to atmospheric dispersion as the plume is advected toward the downwind receptor(s).
Strong southerly low level flow advected surface dew points in the mid 60's into the Lower Ohio Valley, resulting in sufficient instability for supercell convection.
s]F is the flux of solute advected with the water, and f is the flux of solute that diffuses relative to the water according to Fick's law in response to [differential][C.
This suggests that ozone is being advected to other areas to influence local concentrations.
The negative correlation between the quadrant of maximum temperature and wind direction under most combinations of cloud cover and wind speed indicates that the heat island effect for this city was advected down wind.
Changes in the oxygen concentration at the bottom layer could be correlated with a) the oxygen consumption from biological oxidation of organic matter (May 1973, Babenerd 1991, Llanso 1992), or b) intrusions of adjacent oxygen-depleted bottom waters advected by wind influence (Officer et al.
