Atmospheric condition where a parcel of air is warmer that the surrounding air in the immediate environment. This condition causes the parcel to rise in the atmosphere. Also see unstable atmosphere.

instability (pop)

The degree of intrinsic susceptibility of a material to release energy through self-reaction (polymerizing, decomposing or rearranging).

The displayed number continues to vary randomly instead of progressively. See “drift” on page 4.

A state of the atmosphere in which convection takes place spontaneously, leading to cloud formation and precipitation.

A condition reached when a structure or structural member is loaded in which continued deformation results in a decrease in its load-resisting capacity.

A condition reached when a structure or structural member is loaded in which continued deformation results in a decrease in its load-resisting capacity.

It is the condition of the atmosphere when spontaneous convection and severe weather can occur. Air parcels, when displaced vertically, will accelerate upward.

An increased tendency to acquire Chromosome Aberrations when various processes involved in Chromosome replication, repair, or segregation are dysfunctional.

An increased tendency of the Genome to acquire Mutations when various processes involved in maintaining and replicating the Genome are dysfunctional.

Lack of stability of a joint or Joint Prosthesis. Factors involved are intra-articular Disease and integrity of extra-articular structures such as Joint Capsule, Ligaments, and Muscles.

The occurrence of highly polymorphic mono- and dinucleotide Microsatellite Repeats in somatic Cells. It is a form of Genome Instability associated with defects in DNA Mismatch Repair.

A state of the atmosphere in which rising air is warmer than its surroundings and continues to rise.

A state of atmosphere in which the vertical distribution of temperature allows rising, warm air to continue to rise and accelerate. This kind of motion is conducive for thunderstorm development. Instability is a prerequisite for severe weather - the greater the instability, the greater the potential for severe thunderstorms. See lifted index and so [..]

(abbrev. INSTBY)- The tendency for air parcels to accelerate when they are displaced from their original position; especially, the tendency to accelerate upward after being lifted. Instability is a prerequisite for severe weather - the greater the instability, the greater the potential for severe thunderstorms.

The state of equilibrium in which a parcel of air when displaced has a tendency to move further away from its original position. It is the condition of the atmosphere when spontaneous convection and severe weather can occur. Air parcels, when displaced vertically, will accelerate upward, often forming cumulus clouds and possibly thunderstorms.

The tendency for air parcels to accelerate when they are displaced from their original position; especially, the tendency to accelerate upward after being lifted.

The tendency for air parcels in an environment to rise very rapidly and possibly develop into thunderstorms. The greater the instability, the greater the chance for severe weather.
