Engines of Destruction: How Hurricanes Work

The video explores the history and science of hurricanes, starting with legends of typhoons in Japan and the Caribbean. It explains the basic ingredients for hurricane formation, such as heat and wind, and the role of the Coriolis effect. The video compares hurricanes to Carnot's ideal engine, highlighting the processes of evaporation and condensation. It discusses hurricane power and intensity, questioning the need for a Category 6, and emphasizes the impact of climate change on hurricane strength.

What did the Japanese call the typhoons that saved them from Kublai Khan's fleet?

• Kamikaze

• Tsunami

• Cyclone

• Monsoon

What effect causes hurricanes to spin?

• Centrifugal effect

• Gravitational effect

• Coriolis effect

• Magnetic effect

Why can't hurricanes form too close to the equator?

• Too much atmospheric pressure

• Not enough rotational difference

• Insufficient wind speed

• Lack of warm water

What is the primary source of heat that fuels a hurricane?

• Solar radiation

• Warm ocean water

• Volcanic activity

• Geothermal energy

How does evaporation affect the temperature of hurricane winds?

• It heats the winds

• It cools the winds

• It has no effect

• It keeps the temperature constant

What is the maximum theoretical wind speed for hurricanes according to scientists?

• 190 miles per hour

• 210 miles per hour

• 170 miles per hour

• 150 miles per hour

What is the main factor that determines the intensity category of a hurricane?

• Rainfall amount

• Duration

• Wind speed

• Storm size
