A strong El Niño, in the most basic definition, occurs once the average sea surface temperature in the equatorial Pacific is at least 1.5 degrees Celsius (2.7 Fahrenheit) warmer than normal. It's measured in an imaginary box along the equator, roughly south of Hawaii, known as the Nino ...
Scientific understanding of how El Nino and La Nina - as well as other natural temperature cycles over the world's big oceans - affect the weather across the world, is always evolving.
Climate and weather forecasters arethere is an 80 percent chance the climate pattern known as El Niño will continue through the rest of 2015. But what is El Niño? Rain pours from thunderclouds on the U.S. West Coast. Frances Litman | Getty Images El Niño is the name given to ch...
El Niño and La Niña are two faces of a large weather phenomenon. Here are a few frequently asked questions that should clarify what exactly these phenomena are and how they can affect the weather. Q. What is El Niño? A. El Niño is a climate phenomenon that involves the periodic...
And something else is coming into play - the El Nino climate pattern. Lauren Sommer from NPR's climate desk has more. LAUREN SOMMER, BYLINE: When it comes to understanding how climate change is making weather more extreme, heat waves are pretty much the clearest example out there. KAI ...
Typically, during an El Niño, the Pacific jet stream is more robust and provides more moisture for the southern U.S. This pattern can lead to flooding across the Gulf Coast and the Southeast. Drier conditions are usually experienced in the northern tier of the country, and warmer air can...
“So we really want to be able to communicate to all of those regions, all of those different languages, and an emoji is an amazing way of doing that.” Unlike many other weather and climate related events, where longer warning times or visible signs are available, earthquakes move ...
Here’s a look at what these weather events are, why they happen, and whether scientists think they’re getting stronger.
This is despite evidence that a dollar spent on riskreduction saves at least two on reconstruction. Simple improvements to infrastructure (基础设施) can reduce the spread of disease. Better sewers (下水道) make it less likely that heavy rain is followed by an outbreak of the disease of ...
The outbreak did fit another pattern for severe weather events, however, that occur as the atmosphere transitions out of El Niño. And this is exactly what was happening in late April. I study tornadoes and the conditions under which they form. Here’s how...
