Meteorology Post-storm reportPotential Instability

potential energy"The energy a system has by virtue of its position; the negative of the work done in taking a system from a reference configuration, where the potential energy is assigned the value zero, to a given configuration, ...

 


Potential Energy-The energy which a body possesses as a consequence of it's position in the field of gravity, the work required to bring the body up against gravity from a standard level.

Potential energy The energy that a body possesses by virtue of its position with respect to other bodies in the field of gravity.

available potential energy - That portion of the total potential energy that may be converted to kinetic energy in an adiabatically enclosed system.

Terrestrial radiation provides a major part of the potential energy changes necessary to drive the atmospheric wind system and is responsible for maintaining the surface air temperature within limits for livability.

See Convective Available Potential Energy (CAPE).MLLIMean Layer Lifted Index - Lifted Index (LI) calculated using a parcel consisting of Mean Layer values of temperature and moisture from the lowest 100 mb above ground level.

CAPE - Convective Available Potential Energy. A measure of the amount of energy available for convection.

Convective Available Potential Energy (CAPE or B+) It defines the vertically integrated positive buoyancy of an adiabatically rising air parcel on a sounding.

CAPE values are used to rate the potential energy from condensation between the 850 mb level and the 300 mb level in the atmosphere (roughly 5000 to 30,000 ft above the Earth). These integrated values are expressed in joules/kg.

CAPE - Convective Available Potential Energy. The amount of energy that is used by thunderstorms to create the updraft; similarly positive buoyant energy (PBE).

CAPE
Acronym for Convective Available Potential Energy. The amount of energy available to create convection, with higher values increasing the possibility for severe weather.

Work - an energy form arising from the displacement of an object by a force; the conversion of potential energy to kinetic energy.

SBCAPE: CAPE calculated using a Surface based parcel. See Convective Available Potential Energy (CAPE).
SBLI: Lifted Index (LI) calculated using surfaced based parcel. See Lifted Index.

The area between these two lines is representative of the available energy a storm could use to grow. This energy is call CAPE (Convective Available Potential Energy) and comes from the energy released when water condenses.

Mean Layer CAPE - CAPE calculated using a parcel consisting of Mean Layer values of temperature and moisture from the lowest 100 mb above ground level. See Convective Available Potential Energy (CAPE).
