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.

The MWX support data include a well-log porosity sequence {[[phi].sub.i]} to fix spatial fluctuation spectral scaling (5), detailed well-log spatial thermal data to fix the system advected heat flow structure, and sizeable amounts of core-scale poroperm data to fix the poroperm-spatial correlation (6) and the poroconnectivity parameter [alpha] (7).
However, because peak densities of these 2 species occurred within or near the mouths of tidal tributaries, shorter lags may simply reflect increased catchability as larvae were advected downstream and into the study area (for discussions of inflow mechanisms see Drinkwater and Frank (1994), Peebles (2005), and Robins et al.
At high velocity (0.20 m x [s.sup.-1]), eggs were rapidly advected beyond the array, resulting in low overall egg-sperm contact time and consequently low fertilization rate.
The impact is gradually disappearing with increasing forecast length, because the local spatial improvement introduced by the observation at analysis time is advected (and dissipated) by the forecast model.
Because the wind direction was southerly in the earlier part of the day it took a while before the rolls were advected out over the sea.
The advected airmass, however, remains too shallow to produce any typical summer thunderstorms of meaningful intensity.
1991, Dame 1996), and the limiting nature of advected food delivery to bivalves relative to their consumption is well founded in the literature (Wildish & Kristmanson 1979, Incze et al.
Similarly, Palau cove Aurelia occasionally are advected into the lagoon, but have not, according to the molecular data, interbred with lagoon Aurelia for millions of years, again implying reproductive isolation.
Niebauer and Schell (1993) report high densities of zooplankton, especially euphausiids, advected from the northern Bering Sea at least as far north as Point Barrow, and Fissel et al.
According to Suselj and Sood [11], the MABL structure over the North Sea is primarily established by the properties of advected air masses and has small or almost no diurnal cycle.
There is an intermittent sliver of hope with a shallow but active lower middle air moisture range being advected across a good range of our skies: active enough to see healthy convective development but its upward extent restricted by the deep unfavourable airmass directly above.
