Advection of warm moist air over a cooler surface, such as water, causes fog.


1. The transfer of a property of the atmosphere, such as heat, cold, or humidity, by the horizontal movement of an air mass: Today's temperatures were higher due to the advection of warm air into the region.
2. The rate of change of an atmospheric property caused by the horizontal movement of air.
3. The horizontal movement of water, as in an ocean current.

[Latin advectiō, advectiōn-, act of conveying, from advectus, past participle of advehere, to carry to : ad-, ad- + vehere, to carry; see wegh- in Indo-European roots.]

In contrast, the larvae of many species were advected seaward and away from oyster reef habitats during periods of elevated inflow, creating a spatial gap between the larvae and their landward settlement habitat.
Therefore, because the model assumes that sperm come from upstream males, fertilization rates are obviously greater in the immediate vicinity of the female (as close to the spawning male as possible), before eggs are advected from the source.
Larvae spawned on the Northeast Peak recruit to the central part of the Bank as they develop and are advected from there along its southern flank (Lough and Bolz 1989), whereas some larvae spawned throughout the Great South Channel are advected along the northern flank, with the result that there is some mixing between progeny.

In other words, the inflow of colder, denser air, advected from very far south near the Antarctic circle, has a dampening effect on cloud development in the surface and middle air layers.
As chemical signals are advected through moving fluids, they are subjected to hydrodynamic forces such as turbulence, which can have significant effects on the delivery of waterborne chemical cues and the performance ofchemosensory foragers (Weissburg 2000, Webster & Weissburg 2001, Weissburg et al.
