As El Ni

The video explains the differences between El Nino and La Nina, focusing on their impacts on global weather patterns, agriculture, and hurricanes. El Nino causes warming of the Pacific Ocean, affecting weather in regions like India and Australia, while La Nina can lead to droughts in Brazil and Argentina. The phenomena also influence hurricane activity in the Atlantic, with La Nina potentially increasing the number of hurricanes.

What is one of the main effects of El Nino on global weather patterns?

• It cools the Pacific Ocean surface.

• It strengthens the Indian monsoon.

• It increases rainfall in Australia.

• It drags thunderstorms across the Pacific.

How does La Nina potentially affect agriculture in Brazil?

• It has no impact on agriculture.

• It improves soybean crop yields.

• It may lead to drought conditions in southern Brazil.

• It causes excessive rainfall in southern Brazil.

What is a possible positive effect of La Nina on the Indian monsoon?

• It may cause flooding in India.

• It has no effect on the monsoon.

• It might enhance the monsoon's strength.

• It could delay the monsoon season.

How does wind shear influence hurricane development in the Atlantic?

• It strengthens hurricanes.

• It has no effect on hurricanes.

• It weakens hurricanes by disrupting their formation.

• It increases the number of hurricanes.

What is the expected number of hurricanes during a La Nina year compared to an average year?

• No hurricanes at all

• Fewer than average

• More than average

• About the same as average
