Bonnie Gray, Age 11, Of Ramona, Okla., For her question:

What happens when warm and cool air mix?

A conflict between a warm and a cool air mass would depend to a large extent upon the amount of moisture present. The two masses would tend to merge and mingle,

And this would set up weathery turbulence and gusty air currents in the atmosphere. The mixing process would tend to lower the temperature of the warm air and perhaps raise that of the cool air.

When warm, vapor filled air is cooled, some of its vapor is turned into moisture, if the warm air mass carries a full quota of vapor, we could expect rain or hail from the weather conflict. This would occur when its temperature is lowered by mingling with the cooler air.
