Definition of advection in English: advectionnoun ədˈvɛkʃ(ə)nadˈvekSHən mass nounThe transfer of heat or matter by the flow of a fluid, especially horizontally in the atmosphere or the sea. 平流 Example sentencesExamples - There are two processes that change: advection (i.e. transport of the water vapour by the air flow) diffusion (i.e. spreading out by molecular effects)
- A spectacular form of heat advection occurs when molten rock, or magma, erupts from a volcano.
- The very cold air advection in the rear of the cold front brought cooler air to much of the country.
- The first is due to initial conductive cooling; in the second, heat advection is controlled by fluid circulation.
- The second type consists of mountains in the tropical and subtropical dry zones with hot climates at low elevation and only limited advection of moist air, such as the Bolivian Altiplano.
Derivativesverb ədˈvɛktædˈvɛk(t) [with object]Transfer (heat or matter) by the flow of a fluid, especially horizontally in the atmosphere or the sea. 平流 heat can be advected by water that percolates through porous rock Example sentencesExamples - This moisture can be advected to the coast to feed storms and tornadoes.
- However, the general circulation in the Santa Barbara Channel tends to be cyclonic, which often advects cool surface waters eastward along the northern coasts of the Channel Islands.
- As a result of this, in the northern hemisphere, polar air in the lower troposphere is frequently advected into middle latitudes and, occasionally, even as far as subtropical latitudes.
adjective When dissolved solids are carried along with the flowing groundwater, the process is called advective transport or convection. Example sentencesExamples - The advective field for the particles, which are released at intermediate and deep layers off the Somali shelf, is determined by a regional version of the Miami isopycnic coordinate model.
- During summer, vertical advective processes appear to be limited to the upper 200 m, where upwelling in the open water leads to a doming structure.
- Despite the thickness of this relatively stagnant water mass of more than 1000 m, the water age (time since last contact with the atmosphere) is only slightly more than a decade, indicating large-scale advective exchange.
- Running a cloud-resolving model requires putting in essentially the same set of boundary conditions - horizontal advective fluxes and radiative fluxes at the top and bottom of the atmosphere - that one needs for a single-column model.
OriginEarly 20th century: from Latin advectio(n-), from advehere 'bring', from ad- 'to' + vehere 'carry'.
