Unit 3, Lesson 19

Hurricanes form in stages, the first being a tropical depression, which is simply an area of low pressure that has the potential to produce heavy precipitation. The tropical depression has the power as it makes its way toward land to develop into a tropical storm, which is a phenomenon that can drop lots of rain with lots of wind. At the hurricane stage, rain causes flooding and winds become so violent that homes can be destroyed, sometimes even leveled. The eye of a hurricane, which has been speculated to be the safest place in the storm, is a core of cold air around which clouds spin continuously. The spinning, and winds around the storm, push it in different directions.

Problems:

1.) What conditions are necessary for hurricane formation? For a hurricane to form, the following conditions must be present: low air pressure, winds of or above 75 mph, moist, warm air rising from the ocean, and cloud formation high in the sky in a spiral pattern.
