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.

These temperature distributions are controlled by thermal conduction through the salt and enveloping sediments and by advecting warm waters near the salt and in the adjacent minibasins.
Although advecting black holes don't emit much radiation, their feeble spectra do match the overall intensity pattern of the background radiation.
Satellite studies indicate clouds are thicker, and the cloud deck is larger, when smoke is present overhead, consistent with a response to a more stable atmosphere, but the meteorology encouraging the smoke outflows may also be advecting warmer air above the cloud top.
As interesting and unusual as all this may be, the other factor which evolved emphasized the ready ability for a moderately favourable pattern (throughout the lower and middle layers) to become overtly active in advecting moist air into and across Namibia.
Four key features were then identified: (1) cyclogenesis in the Gulf of Mexico, (2) an anticyclone advecting cold arctic air into the region, (3) an upper level shortwave trough approaching the region and (4) a low-level jet (LLJ) in advance of the trough.
A slow anti-cyclonic circulation over southern Angola lead to north-westerly winds over the north western third of Namibia, advecting some moisture ahead of a trough that was then still over the Atlantic.
During these periods, anticyclonic conditions are also common, advecting polluted air from continental Europe into the southeast of the United Kingdom and adding to London's local pollution emissions.
Therefore, long-term climate response of lomas formation due to El Nino may be due to greater moisture availability from fog advecting from warmer sea-surface temperature (SST) windward of the coast of southern Peru.
The final days of 2012 saw an active Tropical Convergence belt close to our northern borders coupled with an ability to tap some of this airmass and advecting into and across northern and central Namibia.
It also provides a reservoir of moist air from which adjacent advecting airflows can tap and bring such moisture further south.
The further outlook maintains a generally northwest bias throughout the week, while active synoptics far to the south see recurrent ridges reappearing and advecting their lower level moisture into the sub continent.
