Is La Niña warm or cold?
La Nina refers to the
periodic cooling of ocean surface temperatures
in the central and east-central equatorial Pacific. Typically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle.
What does a strong La Niña mean?
A strong La Niña is defined as
having sea surface temperatures at least 1.5 degrees Celsius colder than average
.
Why does La Niña happen?
La Niña is caused by
a build-up of cooler-than-normal waters in the tropical Pacific
, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn. Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling.
What are La Niña conditions?
The Short Answer: La Niña is
a weather pattern that occurs in the Pacific Ocean
. In this pattern, strong winds blow warm water at the ocean’s surface from South America to Indonesia. As the warm water moves west, cold water from the deep rises to the surface near the coast of South America.
Does La Niña cause drought?
La Nina occurs when the equatorial Pacific Ocean cools, triggering an atmospheric chain reaction that
can cause droughts
across the western U.S. and roil weather systems globally.
What kind of weather does La Niña bring?

cold and snow to the Northwest and unusually dry conditions to most of
the southern tier of the U.S., according to NOAA’s Climate Prediction Center. The Southeast and Mid-Atlantic also tend to see warmer-than-average temperatures during a La Niña winter.
What’s the difference between El Nino and La Niña?
El Niño events are associated with a warming of the central and eastern tropical Pacific, while
La Niña events are the reverse
, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).
Is La Niña year 2020?
The La Niña climate pattern is
forecast to return this fall and last through the winter of 2021-22
, federal forecasters reported Thursday. … The prediction center said this year’s La Niña (translated from Spanish as “little girl”) is likely to persist through the winter.
When was the last period of La Niña?
Recent years when La Niña Modoki events occurred include 1973–1974, 1975–1976, 1983–1984, 1988–1989, 1998–1999, 2000–2001, 2008–2009, 2010–2011, and
2016–2017
. The recent discovery of ENSO Modoki has some scientists believing it to be linked to global warming. However, comprehensive satellite data go back only to 1979.
What does La Niña mean for winter?
A La Niña year occurs when there are
abnormally cool water pools along the eastern Pacific
. A typical La Niña winter brings dry conditions (and sometimes drought) to the southern tier of the U.S.; conversely, it brings cold and wet conditions (and sometimes heavy flooding) to the Pacific Northwest.
