Answer the following question given this paragraph: 

The warm air at the cold front rises and creates a low pressure cell. Winds rush into the low pressure. This creates a rising column of air. The air twists, rotating counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Since the rising air is moist, rain or snow falls.


Q: What is created when the warm air at the cold front rises and creates a low pressure cell, causing winds to rush into the low pressure?

 Choices:

- Tornado

- Hurricane

- Wind pressure

- rising air column
