What is likely to occur in a location where warm, humid air meets cool, dry air? Explain why this happens.

Rotating column of air that forms from thunderstorms over dry land when moist warm air meets cool dry air head on. ... Because cold air is denser than warm air, the warm air rises over the cold air. Clouds storms and rain often come with warm fronts. As the warm air rises, its water vapor condenses. Clouds form, and precipitation falls. If the warm air is very humid, precipitation can be heavy. Temperature and pressure differences between the two air masses cause winds.

Sorry if this doesn't help you... Stay safe and have a great weekend :D
