Question

Quizplus · Accepted Answer

If an air parcel continues to move upward on its own accord after being given a small push upward, then it implies that the parcel is less dense than its surroundings. In an unstable atmosphere, the temperature decreases rapidly with height, making the air parcel warmer than its surroundings, leading to upward acceleration and growth of the parcel, resulting in convection and often leading to the formation of clouds and precipitation. Therefore, an upward-moving air parcel indicates an unstable atmosphere.
