Quick Answer: What Does El Nino Mean For California??

El Niño in Southern California.

El Niño is characterized by warmer than average sea surface temperatures in the Eastern equitorial Pacific.

Impacts due to flooding, unusually large waves, heavy precipitation, and erosion are expected in Southern California.

How does El Nino affect the West Coast?

During La Niña, increased precipitation is diverted into the Pacific Northwest due to a more northerly storm track. During the El Niño portion of ENSO, increased precipitation falls along the Gulf coast and Southeast due to a stronger than normal, and more southerly, subtropical jet stream.

How does El Nino affect La Nina California?

El Niño (the boy), which is characterized by the weakening of the equatorial winds, results in a warm phase in the eastern tropical Pacific that reduces the productivity of marine ecosystems all the way north to Alaska. The Gulf of California is not immune to the effects of El Niño/La Niña events.

How does El Nino and La Nina affect the US?

El Nino is the warming of the Pacific Ocean off of the western coast of South America near Ecuador and Peru. Because the Earth system is interconnected, changes in the ocean cause changes in the atmosphere. El Nino and La Nina events not only impact ocean temperatures in the tropical Pacific, but also global weather.

Does El Nino bring rain to California?

Instead of coming ashore in the Pacific Northwest as usual, the southern jet stream hits California, carrying moisture and storms. In general, the effect of El Niño on California is increased rainfall with accompanying floods, landslides, and coastal erosion.

Is El Nino good for California?

La Niña typically keeps California warm and dry. El Niño years often have a strong warming of equatorial waters in the eastern and central Pacific Ocean. The subtropical jet stream often brings wet weather to California as it comes ashore in California instead of in the Pacific Northwest during a normal winter.
