Aquatic Science

A hurricane is a large, rotating storm system that forms over water, bringing high winds, rough seas, and heavy rain. Hurricanes occur where —

• the ocean has extremely high tides.

• ocean water is the coolest, near the pole in the late winter.

• ocean water is the warmest, near the equator in the late summer.

• the ocean has extremely low tides.

During an El Niño weather event, trade winds across the Pacific Ocean weaken, and waters along the coast of Peru and Ecuador become unusually warm. The warmer ocean waters result in —

• the formation of numerous thunderstorms along the South American coast.

• many days of clear, cold weather along the South American coast.

• many days of clear, warm weather along the South American coast.

• the formation of numerous hurricanes along the South American coast.

Tropical depressions tend to originate over —

• sandy deserts, where water is likely to rise as vapor and remain in the air as clouds.

• sea ice, where water is likely to rise as vapor and later fall as snow.

• large lakes, where water is likely to rise as vapor and remain in the air as fog.

• warm oceans, where water is likely to rise as vapor and later fall as rain.

During the time period that an El Niño is occurring —

• The food supply for fish in the region is increased.

• There is a buildup of warm water off the coast of South America.
