How do ocean currents affect global weather patterns?.

Ocean currents significantly influence global weather patterns by redistributing heat and moisture around the Earth. They affect temperature variations and precipitation levels, contributing to climate zones and extreme weather events.

Key Facts

• Ocean currents transport about 25% of the Earth's heat from the equator to the poles.
• The Gulf Stream alone raises temperatures in Western Europe by up to 10°C.
• Changes in currents can lead to events like El Niño and La Niña, affecting global weather patterns.
• Ocean currents influence monsoon patterns in South Asia, impacting agriculture and economies.

Examples or Use Cases

• The Gulf Stream's warmth supports temperate climates in Europe.
• The California Current helps cool the west coast of the USA, affecting local weather.

FAQs

• What causes ocean currents? Ocean currents are driven by wind, the Earth's rotation, and differences in water density.
• How do ocean currents affect hurricanes? Warm ocean currents can intensify hurricanes by providing additional heat and moisture.
