El Niño

El Niño is a climate phenomenon originating in the Pacific Ocean, affecting global weather patterns. It alters atmospheric pressure and ocean temperatures, causing extreme weather events like droughts, floods, and storms worldwide. The interaction between the atmosphere and ocean currents plays a crucial role in climate dynamics, with El Niño disrupting these patterns every 2 to 7 years. Its effects are felt globally, from altered monsoons in India to winter storms in California, making it a significant climatological mystery.

What role does the Pacific Ocean play in global climate?

• It only affects the climate of nearby regions.

• It is responsible for transporting heat around the planet.

• It has no impact on global climate patterns.

• It only causes droughts in arid regions.

How do the temperature differences in the Pacific affect climate?

• They lead to tropical storms in the west and dry conditions in the east.

• They cause the same climate in both the east and west.

• They create uniform weather conditions across the Pacific.

• They have no effect on weather patterns.

What happens to the winds during an El Niño event?

• They only affect the eastern Pacific.

• They have no change in direction or strength.

• They calm down and may reverse direction.

• They become stronger and move westward.

Which of the following is a global impact of El Niño?

• Hurricanes in the Arctic.

• Droughts in northern Europe.

• Winter storms in California.

• Increased rainfall in the Sahara Desert.

How often does El Niño typically occur?

• Once every decade.

• Every year without fail.

• Only once in a century.

• In periods of 2 to 7 years on average.
