Where do hurricanes form?
Solution
Hurricanes, also known as tropical cyclones, typically form over warm ocean waters near the equator. Here are the steps of how they form:
-
Warm Ocean Waters: Hurricanes need water that is at least 26.5 degrees Celsius. This warm water is the fuel for the hurricane.
-
Atmospheric Conditions: The atmosphere must cool off very quickly the higher you go. Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface.
-
Disturbance: Hurricanes often start as a tropical disturbance. This is an area over warm ocean waters where rain clouds are building and wind patterns start to form.
-
Storm Formation: The wind patterns and moisture from the warm ocean water combine to cause the storm to grow. The storm starts to spin and grow due to the Coriolis effect, which is caused by the Earth's rotation.
-
Hurricane Formation: As the storm spins faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye. When the winds in the rotating storm reach 39 mph, the storm is called a "tropical storm." And when the wind speeds reach 74 mph, the storm is officially a "hurricane."
So, hurricanes form in tropical or subtropical areas over warm ocean water, usually in the summer or fall. Most hurricanes form in the Atlantic and Pacific Oceans.

Hurricanes that affect the US usually form in the Northern Atlantic Ocean. As solar radiation warms the ocean surface evaporation increases. The warmer the temperatures, the greater the rate of evaporation. As you may recall, warm, moist air rises, expands and cools to the dew point and clouds form. Energy and water vapor continue to be added to the atmosphere. This creates a low pressure area, known as a tropical depression. If winds are sustained above 39 miles per hour it is considered a tropical storm. If the winds are over 74 miles per hour it becomes a hurricane. Most hurricanes occur in late summer early autumn because this is when the ocean surface is warmest. They are the most destructive storms. High winds, storm surges (ocean water pushed onto the coast) and major flooding occur. One more thing that adds to the hurricane Category Winds 1 74-95 mph 2 96-110 mph 3 111-130 mph 4 131-155 mph 5 > 155 mph disaster is that tornados can form. A hurricane is sometimes referred to as a cyclone because it is such a large area of low pressure. A typhoon is the same as a hurricane, however forms over the Northwest Pacific Ocean. Hurricanes are fairly easy to predict because advancements in weather radar and satellite technology allows meteorologists to watch them develop and keep track of their path. Where exactly they hit land is not full proof. If a hurricane appears to pose a threat to your area within 48 hours, a hurricane watch is issued. A warning is issued if conditions are expected within 36 hours. When you are ordered to evacuate LEAVE THE AREA. Need to know: 1. Where do hurricanes form? 2. How do clouds form in a hurricane? 3.
