Understanding Ocean Currents: El Niño and La Niña Phenomena
Explore the impacts of El Niño and La Niña phenomena on weather patterns, from unusual warming (El Niño) to cooling (La Niña) of the Pacific Ocean. Discover how these phenomena affect regions like North America, Southern California, and North Carolina, influencing temperature, precipitation, and hurricane occurrences.

Ocean Currents El Ni o and La Ni a
Changes ~ A change in ocean temperature can affect weather patterns for long periods of time. ~Every few years, such a change occurs in the Pacific Ocean.
El Nio ~ An unusual warming of the surface water in the eastern Pacific Ocean near the equator is known as El Ni o. ~This causes the jet stream to be disrupted (usually it is pushed south) which affects weather patterns across North America.
El Nio ~ This leads to an increase in temperature and precipitation in the southern part of the United States, especially southern California.
El Nio ~ North Carolina experiences wetter than normal winters during an El Ni o. ~It also decreases the number of Atlantic Hurricanes.
La Nia ~An unusual cooling of the surface water in the eastern Pacific Ocean near the equator is known as La Ni a. ~This causes opposite weather patterns from an El Ni o.
