Explanation:

Thunderstorm:
When warm, moist air mixes with cool, dry air, it can create a thunderstorm. Thunderstorms are characterized by heavy rain, thunder, lightning, and sometimes hail. The rapid upward movement of warm, moist air causes the formation of cumulonimbus clouds, which are associated with thunderstorms.

Tornado:
A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud. While tornadoes can occur during thunderstorms, they are not directly caused by the mixing of warm, moist air with cool, dry air. Instead, tornadoes are typically associated with severe thunderstorms called supercells.

Tsunami:
A tsunami is a series of ocean waves caused by a sudden, large-scale disturbance in the ocean, such as an underwater earthquake, volcanic eruption, or landslide. Tsunamis are not related to the mixing of warm, moist air with cool, dry air.

Hurricane:
Hurricanes form over warm ocean waters when warm, moist air rises and cools, creating condensation and cloud formation. While hurricanes do involve the interaction of warm, moist air with cooler air, they are different from thunderstorms which occur over land.

Therefore, when warm, moist air mixes with cool, dry air, it is most likely to result in a thunderstorm.
