• 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

• Level of free convection — The level of free convection (LFC) is the altitude in the atmosphere where the temperature of the environment decreases faster than the moist adiabatic lapse rate of a saturated air parcel at the same level.The usual way of finding the LFC is to… …   Wikipedia

• level of free convection — The level at which a parcel of air lifted dry adiabatically becomes saturated. It would then rise moist adiabatically and being warmer than the surrounding atmosphere would continue to rise in a conditionally unstable atmosphere. The dry… …   Aviation dictionary

• Atmospheric convection — Conditions favorable for thunderstorm types and complexes Atmospheric convection is the result of a parcel environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to… …   Wikipedia

• Rayleigh–Bénard convection — Bénard cells. Rayleigh–Bénard convection is a type of natural convection, occurring in a plane of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells. Rayleigh–Bénard convection is one… …   Wikipedia

• Maximum parcel level — The maximum parcel level (MPL) is the highest level in the atmosphere that a moist convectively rising air parcel will reach after ascending through the free convective layer (FCL) and reaching the equilibrium level (EL), near the tropopause. As… …   Wikipedia

• Convective condensation level — The convective condensation level (CCL) represents the height where an air parcel becomes saturated when lifted adiabatically to achieve buoyant ascent. It marks where cloud base begins when air is heated from below to the convective temperature …   Wikipedia

• Lifted condensation level — The lifted condensation level or lifting condensation level (LCL), represents the height at which an air parcel being lifted dry adiabatically will become saturated because of adiabatic cooling (caused by expansion) and condense into cloud. It… …   Wikipedia

• Deep convection — is a convective process in a medium, usually in an atmosphere or ocean, that in some sense spans the vertical. Within the atmosphere, this means from the surface to above the 500 hPa level, generally stopping at or defining the tropopause at… …   Wikipedia

• Equilibrium level — In meteorology, the equilibrium level (EL), or level of neutral buoyancy (LNB), is the height at which a rising parcel of air is at a temperature of equal warmth to it. This means that unstable air is now stable when it reaches the equilibrium… …   Wikipedia

• convective condensation level — The lowest level at which condensation will occur as a result of convection from surface heating …   Aviation dictionary
