Best Answer

A cold front forms when colder air advances toward warm air. The cold air wedges under the warm air like a plow. As the war air is lifted, it cools and water vapor condenses, forming clouds. When the temperature difference between the cold and warm air is large, thunderstorms and even tornadoes may form.

Are there tornadoes when a cold front and warm front meet?

No. When a cold front meets a warm front you get an occluded front. A simple cold front is more likely to produce severe weather than an occluded front is. This is a common source of confusion as a colf front is what forms when coooler air pushes into warmer air. Tornadoes are often associated with cold fronts, but the front is not the direct cause. When a cold front moves through and there is enough instanility ahead of it, thunderstorms can form, but only when a number of other conditions are present can these storms produce tornadoes.
