El Nino and Why We Can't Predict the Weather

The video explains El Nino, a weather phenomenon causing global climate impacts. It describes how El Nino and La Nina occur due to changes in Pacific Ocean winds and temperatures. The video highlights the challenges in predicting El Nino events due to their irregular cycles and introduces Chaos Theory, explaining how small changes can lead to unpredictable outcomes. The video emphasizes the complexity of weather systems and the inherent uncertainties in forecasting.

What is the primary cause of the sea level difference between Indonesia and Peru during normal conditions?

• The Coriolis effect and east-west winds

• The gravitational pull of the moon

• The Earth's magnetic field

• The rotation of the sun

Which of the following statements about the 1997 El Nino event is true?

• It resulted in increased rainfall in Kenya.

• It had no impact on global weather patterns.

• It caused droughts in California.

• It was the weakest El Nino on record.

How often can El Nino events occur?

• Every two to seven years

• Every century

• Every decade

• Every year

What accidental discovery did Edward Lorenz make in 1961?

• The Coriolis effect

• The butterfly effect

• The greenhouse effect

• The ozone layer depletion

What does Chaos Theory suggest about weather prediction?

• It is unaffected by initial conditions.

• It can be predicted accurately for years.

• It is impossible to predict weather beyond a few days.

• It is always accurate.

What is the 'butterfly effect' in Chaos Theory?

• Butterflies causing tornadoes

• Small changes leading to large impacts

• Predictable weather patterns

• The effect of butterflies on climate

Why is it difficult to predict weather accurately over long periods?

• Because of the lack of technology

• Due to the complexity and unpredictability of atmospheric systems

• Due to the simplicity of atmospheric systems

• Because weather never changes
