The sideways movement of air in the lower atmosphere due to the differences in air pressure (commonly called wind). Process of transfer of air mass properties by the velocity field of the atmosphere.
transportation of contaminants by the flow of a current of water or air
The transport of dissolved contaminants by the bulk movement of groundwater flow; the main process driving the movement of dissolved contaminants.
Horizontal movement of meteorological properties, such as heat or humidity.
(meteorology) the horizontal transfer of heat or other atmospheric properties
The process by which solutes are transported by the bulk of flowing fluid such as the flowing ground water.
The transfer of an atmospheric property, such as temperature, by the movement of air, especially horizontally. In environmental science, the movement of water, either internally or externally, through a sediment bed.
The process of transfer (of an air-mass property) by virtue of motion.
Horizontal motion, such as wind.
This is when heat or moisture is transferred horizontally. The atmosphere at all levels is usually in motion, with the low to middle troposphere being areas of significant advection, and thickness lines of 500-1000hpa are often used.
The horizontal transfer of any atmospheric property (hot air, cold air, moist air, etc.) by the wind. "Warm Air Advection" is the term used to describe warmer air blowing into a region.
The process by which chemicals and heat are transported along with the bulk motion of flowing gas or liquid. For example, nitrates move through soils and aquifer formations due predominantly to the bulk motion or movement of water.
The transfer of thermal energy by the ingress of air of different temperature or humidity to that of the local air by predominantly horizontal motion in the atmosphere.
The horizontal transport of air or atmospheric properties. Commonly used with temperatures, i.e., "warm air advection", or moisture, i.e., "moisture advection".
The horizontal movement of an air mass that causes changes in the physical properties of the air such as temperature and moisture.
The usually horizontal movement of a mass of water (as in an ocean current); or the transport of pollutants or plankton by such movement.
The process where liquids are transported at the velocity of the fluid. It is the primary transport mechanism for groundwater.
The predominately horizontal large-scale movement of air that causes changes in temperature or other physical properties. In oceanography, advection is the horizontal or vertical flow of seawater as a current.
The horizontal motion of air (parallel to sea level)
Process of transport of an atmospheric property, or substance within the atmosphere, solely by the mass motion of the atmosphere.
is horizontal transport of any property, such as heat or humidity.
the transport of an atmospheric property (e.g., temperature) by the wind
Horizontal movement of air, moisture, or heat.
Transport of an atmospheric property by the wind. See cold advection, moisture advection, warm advection.
The transfer of atmospheric properties by horizontal movement of air. Most commonly used in reference to transfer of warmer or cooler air.
The process by which solutes are transported by the bulk motion of the flowing groundwater.
The transfer of heat by the horizontal movement of air or water, such as a warm wind or ocean current.
The horizontal transfer of any property in the atmosphere by the movement of air (wind). Examples include heat and moisture advection.
The horizontal transportation of air or atmospheric properties.
(Abbrev. ADVCTN)- Transport of an atmospheric property by the wind.
the horizontal transport of air, moisture, vorticity or other atmospheric properties; commonly used in describing the transport of moisture and temperature.
Horizontal movement of air or atmospheric properties, such as temperature, moisture and vorticity, to indicate the trends of that property; "horizontal convection".
The process of transport of an atmospheric property solely by the mass motion ( velocity field) of the atmosphere; also, the rate of change of the value of the advected property at a given point. Advection may be expressed in vector notation by where is the wind vector, φ the atmospheric property, and ∇φ the gradient of the property. In three-dimensional Cartesian coordinates, it is where , , and are the wind components in the eastward, northward, and vertically upward directions, respectively. The first two terms compose the horizontal advection and the last term is the vertical advection. Also, it should be noted that the property φ may itself be a vector field. Often, particularly in synoptic meteorology, advection refers only to the horizontal or isobaric components of motion, that is, the wind field as shown on a synoptic chart. Regarding the general distinction (in meteorology) between advection and convection, the former describes the predominantly horizontal, large-scale motions of the atmosphere, while convection describes the predominantly vertical, locally induced motions. In oceanography, advection refers to the horizontal or vertical flow of seawater as a current.
Transport or transfer of heat, by means of the movement of a media such as water in the system.
Advection is transport in a vector field. A good example is the transport of pollutants or silt in a river: the motion of the water carries these impurities downstream (see pigpen problem). Any substance can be advected, in a similar way, in any fluid.
