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
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
Free convective layer — In atmospheric sciences, the free convective layer (FCL) is the layer of conditional or potential instability in the troposphere. It is a layer of positive buoyancy (PBE) and is the layer where deep, moist convection (DMC) can occur. On an… … 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
