how is el niño formed

Record temperatures lure ‘heat tourists’ to Death Valley National Park. The fast-moving Zogg fire, which started Sunday in Shasta County, has killed three, destroyed 146 structures and prompted numerous evacuations. When this happens, the cooler water underneath rises up toward the surface of the ocean near South America. "El Niño tends to increase upper-level westerly winds across the Caribbean into the tropical Atlantic, tearing apart hurricanes as they try to form," …

How could this year's El Niño affect the Dallas-Fort Worth area? Weather depends a lot on ocean temperatures. The development of El Niño events is linked to the trade winds. The pattern can shift back and forth irregularly every two to seven years, and each phase triggers predictable disruptions of temperature, precipitation, and winds.

This is one of the clearest connections that meteorologists follow. Miraculously, one landmark survived.

The colder water carries more nutrients for fish than the warm water does. El Niño is a periodic natural warming of seawater in the tropical Pacific. La Niña can be seen as the counterpart or opposite of the El Niño phenomenon.

Meteorologists don’t quite know enough about what La Niña does in the fall to say what it could mean for the record-bad California wildfire season going on now, Diffenbaugh said. For the next few months, he said, what matters more is when the fall rains begin. One effect is that El Niño causes wind conditions in the upper atmosphere that slow down developing storms in the Atlantic Ocean. La Niña has a tendency to shift snowstorms more northerly in winter, Halpert said. El Niño Conditions During El Niño, warm surface water appears farther east and is spread over a broader area. It is among the biggest influences on weather and climate in the United States and around the world.

A La Niña usually means a more active season with more and perhaps stronger storms. Often, El Niño is followed immediately by La Niña, as if the warm water is sloshing back and forth across the Pacific. All rights reserved. Extreme fire danger in Southern California amid new heat wave.

WHAT DOES LA NINA MEAN?

El Niño occurs when the trade winds are weaker than normal, and La Niña occurs when they are stronger than normal. So far, this one is fairly weak. The writer revisits a painful memory from 1992, comparing it to his father’s trauma and the current firestorm at the Los Angeles Times. Stay up to date with important alerts. He is a graduate of the University of Texas at Dallas. In El Niño conditions, the trade winds are weak or may even blow in the opposite direction from normal. The last La Nina went from fall 2017 to early spring 2018. Drought conditions are already pretty bad in west Texas, Arizona, Utah and Colorado, Halpert said.

Officially, federal forecasters said there's no reliable way to predict what El Niños might mean for the spring thunderstorm and tornado season. That really depends on where you are. Many supporters of Biden and Trump fear violence is likely in November. That’s because the first El Niño was characterized and identified around Christmas by fishermen in South America.

Deadly Zogg fire remains out of control; reinforcements called in. The National Oceanic and Atmospheric Administration announced the La Niña’s formation on Thursday after meteorologists had watched it brew for months. Both cycles typically peak in December. A neutral ENSO is best for agriculture, the study found. Review: ’Scuse me while I ‘Kiss the Ground’: How soil might be Earth’s climate change savior. With so many limitations to coronavirus data, what can we trust?

A Black reporter recalls racism in the newsroom and finally gets his day of reckoning. This week's storms are courtesy of an "atmospheric river" that funnels water vapor from the tropics to the West. A study published in 2015 in the British journal Nature Geoscience indicated it brings a quieter tornado season in the Southeast. This year started with a brief, weak El Niño. During an El Niño, water temperatures in the central and eastern tropical Pacific Ocean get a few degrees warmer than average, typically at least three to five months. It and its counterpart, La Niña, are “naturally occurring climate patterns” that occur every two to seven years on average and can affect weather patterns, ocean conditions and even marine fisheries, the agency says.
