In what condition will warm and buoyant air keep rising?

Warm and buoyant air continues to rise under conditions classified as absolutely unstable. In this state, the air parcel is warmer (and thus less dense) than the surrounding environment at all altitudes. Because it is buoyant, it experiences a continued upward force that allows it to rise freely. The concept of buoyancy is central in meteorology; when the air parcel is warmer than the surrounding air, it will rise until it reaches an equilibrium with the environment or until it cools and becomes denser than its surroundings.

In contrast, absolutely stable air resists upward motion and will not rise unless forced, while conditionally unstable air requires certain conditions (like reaching a specific height or temperature) to become buoyant. Neutral air does not exhibit tendencies to rise or fall. Thus, the characteristic of absolutely unstable air is its ability to rise continuously without external force, contributing to significant vertical development in weather phenomena such as thunderstorms and convective currents.
