Trade Winds/El Nino El Nina/Quiz

Because of the tilt of Earth's rotation, wind/air moves to the right in the Northern Hemisphere. It moves to the left in Southern Hemisphere. Imagine driving in a car leaving the Equator heading straight north. Your car would be push to right if it were air/wind. If you were leaving poles and headed towards the equator, your car would be heading to right also. But remember you are heading from North to South now. So even though you are being pushed to the right your now being push towards the west because going south. When you were driving North, you were being push towards East. It is the opposite in the SOUTHERN HEMISPHERE air and wind is pushed to left in same manner. This is all called

• Centrifugal force
• Jet stream
• Trade winds
• Coriolis effect

Answer explanation

also has an effect on ocean waves in same manner

The air pressure of the Polars and The Equator play a role in wind. Low pressure or High pressure is at Equator?

• High pressure
• Low pressure

Why is there low pressure at Equator?

• High pressure due to cold ocean currents.
• Low pressure caused by volcanic activity.
• High humidity leading to dense air accumulation.
• There is low pressure at the Equator due to intense solar heating causing air to rise.

There are some winds that flow toward Equator. These winds will be pushed to the right from the 30 N latitude to 30 South Latitude. That means they are going from East to West. What are these winds called?

• Polar winds
• Prevailing westerlies
• Trade winds
• Jet streams

Trade winds play a part in El Nino and La Nino. In El Nino what happens to these winds?

• The trade winds strengthen significantly.
• The trade winds remain unchanged.
• The trade winds weaken or reverse direction.

Because these trade winds weaken during El Nino, what happens to the Pacific Jet Stream?

• The Pacific Jet Stream shifts entirely to the Atlantic Ocean.
• The Pacific Jet Stream remains unchanged during El Nino.
• The Pacific Jet Stream becomes more variable and often stronger. It shifts more south as the trade winds lose strength

• The Pacific Jet Stream becomes weaker and less variable.

Which way does Jet Streams move?

• Jet streams move vertically up and down.
• Jet streams move from west to east.
• Jet streams move from east to west.
• Jet streams move in circular patterns.

Answer explanation

opposite of trade winds

During La Nina, the winds strengthen instead of weakening like El Nino. What does this do to the jet stream?

• The jet stream shifts southward, leading to warmer and drier conditions.
• The jet stream remains unchanged and has no impact on weather patterns.
• The jet stream shifts more towards the north.

• The jet stream weakens and causes drier conditions everywhere.

So when La Nina is making the Trade Winds get stronger, there is more surface area water being pushed to the West. So the water in the Pacific nearer the West Coast of California now has water rising from the bottom that is more

• The water is cooler.

• The water is warmer.
• The water is more polluted.
• The water is less salty.

During El Nino, the winds are not as strong. They are not being pushed to the West as hard or even pushed to the East. This means that surface water which is warmer on top, stays or moves more to East. So the water in the Pacific near California is ___ than it normally would be.

• colder
• unstable
• neutral
• warmer
