Instability strip

The term "instability strip" can refer to several different concepts depending on the context, but it is most commonly used in meteorology and atmospheric science. In this context, an instability strip is a region in a diagram that represents the stability properties of the atmosphere, particularly with regard to convection. In meteorology, the instability strip typically refers to a band on a thermodynamic diagram, such as a skew-T log-P diagram, where certain conditions indicate that the air is unstable.
