Equilibrium Level
(or EL) - On a sounding , the level above the level of free convection (LFC) at which the temperature of a rising air parcel again equals the temperature of the environment. See picture  The height of the EL is the height at which thunderstorm updrafts no longer accelerate upward. Thus, to a close approximation, it represents the height of expected (or ongoing) thunderstorm tops. However, strong updrafts will continue to rise past the EL before stopping, resulting in storm tops that are higher than the EL. This process sometimes can be seen visually as an overshooting top or anvil dome . The EL typically is higher than the tropopause , and is a more accurate reference for storm tops.
