  • Advection — Advection, in chemistry, engineering and earth sciences, is a transport mechanism of a substance, or a conserved property, by a fluid, due to the fluid s bulk motion in a particular direction. An example of advection is the transport of… …   Wikipedia

  • advection —    1. The process whereby solutes are transported by the bulk mass of flowing fluid [6].    2. Phenomenon of cool air mass intruding and interrupting evaporation and causing condensation due to heat loss [16].    See also convective transport …   Lexicon of Cave and Karst Terminology

  • Contour advection — simulation Contour advection is a Lagrangian method of simulating the evolution of one or more contours or isolines of a tracer as it is stirred by a moving fluid. Consider a blob of dye injected into a river or stream: to first order it could be …   Wikipedia

  • Diffusion process — For the marketing term, see Diffusion of innovations. In probability theory, a branch of mathematics, a diffusion process is a solution to a stochastic differential equation. It is a continuous time Markov process with continuous sample paths. A… …   Wikipedia

  • cold advection — The process of advection (transfer of heat by horizontal motion) when cold air mass replaces a warm air mass …   Aviation dictionary

  • climate — /kluy mit/, n. 1. the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years. 2. a region or… …   Universalium

  • Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… …   Wikipedia

  • Accretion disc — An accretion disc (or accretion disk) is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a central body. The central body is typically either a young star, a protostar, a white dwarf, a neutron star,… …   Wikipedia

  • Chaotic mixing — An example of chaotic mixing In chaos theory and fluid dynamics, chaotic mixing is a process by which flow tracers develop into complex fractals under the action of a time varying fluid flow. The flow is characterized by an exponential growth of… …   Wikipedia
