Hurricanes and Tropical Storms Overview

Hurricane Overview

• Cyclones, typhoons, and hurricanes are powerful storms varying by region.
• These storms develop in warm tropical waters, particularly in the Atlantic Ocean.

Formation and Structure

• Hurricanes form from clusters of thunderstorms absorbing warm, moist air.
• This warm air rises, converting into energy, which fuels the hurricane's winds.
• The center of a hurricane is called the eye, typically calm, measuring 20 to 30 miles across.
• Surrounding the eye is the eye wall, characterized by intense winds and towering clouds.
• Rain bands, which can be tens of miles wide, extend outward, producing heavy rain and potential tornadoes.

Classification and Wind Speeds

• A tropical storm becomes a hurricane when wind speeds reach 74 miles per hour.
• Hurricanes are classified on the Saffir-Simpson scale from 1 to 5 based on wind speed and potential damage.

Dangers of Hurricanes

• Storm surge is a significant threat, caused by winds pushing seawater onto land.
• Surge can reach heights of up to 20 feet and affect areas up to 100 miles inland.
• Around 90% of hurricane-related fatalities result from storm surge.

Environmental Role

• Hurricanes contribute to global climate regulation by transferring heat from the equator to the poles.
• They maintain Earth's temperature stability, despite their destructive capabilities.

Advancements in Understanding

• Scientific advancements lead to improved hurricane tracking and prediction.
• Early warning systems have been developed, enhancing safety and infrastructure preparedness.
• Continuous research aids in minimizing hurricanes' impacts on human communities.
