This type of front forms when a rapidly moving cold air mass runs into a slowly moving warm air mass.
What is a cold front?
What happens as air gets warmer?

What is a hurricane?
Why don't cities that receive lake-effect snow in the winter also receive lake-effect rain in the summer?
The waters of the Great Lakes are cooler than the surrounding land in the summer. Therefore, west winds blowing across the Great Lakes do not pick up moisture as they do in the winter when the lakes are warmer than the surrounding land.

Hurricanes that strike the East Coast of the United States are most common in what months?
What are August, September, and October?
Why don't hurricanes form over the Northern Atlantic Ocean?
