An air parcel is considered unstable when it continues to rise until it reaches an altitude at which the surrounding air has a similar temperature. This means that the air parcel is warmer and less dense than the surrounding environment, leading to it being buoyant and continuing to rise until it reaches a point of neutral buoyancy with the surrounding air. This is indicative of convective activity and can lead to the formation of clouds and precipitation.
