Which atmospheric condition is conducive for the development of thunderstorms?

High humidity and low pressure are key elements that contribute to the development of thunderstorms. When the atmosphere is saturated with moisture, it provides the necessary fuel for convection, which is a process where warm, moist air rises. As this air ascends, it cools and condenses, forming clouds and, eventually, thunderstorms. Low pressure in the atmosphere indicates that warm air is rising, further enhancing the conditions needed for thunderstorm development.

High humidity not only supports the formation of clouds but also leads to the release of latent heat, which can further enhance upward motion in the atmosphere. This combination of factors creates an unstable environment, critical for the formation of cumulonimbus clouds, which are characteristic of thunderstorms.

In contrast, stable atmospheric conditions, cool and dry air, and stable winds inhibit the vertical development of clouds and diminish the likelihood of thunderstorms. These conditions lead to a more stable atmosphere, where air does not rise effectively, preventing the growth of the convective systems necessary for thunderstorms.
