Global Weather Anomalies (El Niño and La Niña)Atmospheric
This shift drives drastic weather changes, such as heavy flooding in California and severe, dry droughts in Australia.
What is Global Impacts?
The boundaries between warm and cold currents create sharp temperature differences in the atmosphere. These zones can alter air pressure and direct the paths of storms across the globe.
What is Steering Storm Tracks?
Cold water does not evaporate easily. As a result, the air blowing over cold currents is dry, which can create coastal deserts—such as the Atacama Desert in South America or the Namib Desert in Africa.
How does Cold Currents Create Deserts?
Warm currents heat the air above them. For example, the warm Gulf Stream carries tropical heat to Northern Europe, keeping its weather much milder than other areas at the same latitude
What is Warming High Latitudes?

Changes in ocean currents can completely flip global weather. During El Niño, standard Pacific currents weaken or reverse, causing the sea surface to warm up.
What is Atmospheric Disruptions?
Warm ocean currents provide the thermal energy required to spawn and intensify tropical storms and hurricanes. As storms pass over warm currents like the Gulf Stream, they absorb heat and water vapor, rapidly gaining strength.
What is Fueling Hurricanes?
Warm ocean water evaporates quickly, pumping moisture into the Air. This leads to high humidity, cloud formation, and heavy rainfall along coastal regions exposed to warm currents
How does Warm Currents Create Rain?
Ocean surface currents carry warm water from the equator toward the poles, and cold water from the poles back toward the Equator.
