NASA | Exploring Energy: Hurricanes

The video explains how hurricanes derive energy from warm ocean water, with water vapor carrying latent heat into the atmosphere. This heat is released when the vapor condenses, powering the hurricane. Afterward, the heat dissipates into space. NASA and NOAA research these processes to improve hurricane prediction. A classroom activity using NASA data allows students to study sea surface temperature changes during hurricanes, focusing on Hurricane Rita. The video also covers how hurricanes affect ocean circulation and temperature, causing upwelling and cooling.

What is the primary source of energy for hurricanes?

• Cold ocean currents

• Warm ocean water

• Solar radiation

• Wind currents

What is the term used for the heat that is released when water vapor condenses in a hurricane?

• Sensible heat

• Specific heat

• Radiant heat

• Latent heat

How does the top of a hurricane behave as it dissipates?

• It becomes denser

• It absorbs heat from the surroundings

• It radiates heat into space

• It cools down rapidly

What is the purpose of NASA and NOAA's research on hurricanes?

• To increase hurricane frequency

• To stop hurricanes from forming

• To predict the strength and paths of hurricanes

• To create more hurricanes

What effect do hurricanes have on sea surface temperature?

• They increase the temperature

• They have no effect

• They cause a dramatic decrease

• They stabilize the temperature
