Under which condition will thunderstorm chances be lower?
Answer and explanation
Correct answer: Stable atmosphere and weak uplift
Thunderstorms need moisture, instability, and a lifting mechanism that allows air to rise and continue rising. In a stable atmosphere, a lifted parcel tends to become relatively cooler and denser than its surroundings, so it sinks back instead of developing strong convection. Weak uplift also prevents cloud growth. Therefore, stable conditions with weak upward motion reduce thunderstorm chances, whereas the other options favour storm development.
