Will 2020 be a hot summer?
We predict summer 2020 will be warmer and drier tan average overall. We think this summer will be around 1C to 1.5C above the long term average. GWV expects all three summer months to have above average temperatures with an equal chance of July or August being the hottest month of the summer overall.
Is 2021 an El Niño year?
La Niña has peaked, but impacts continue There is a 65% likelihood that it will persist during February-April, with a 70% chance that the tropical Pacific will return to ENSO-neutral conditions by the April-June 2021 season, according to WMO’s El Niño-La Niña Update.
How can we reduce the effects of El Niño?
Consider installing additional drainage, hardscapes, bark and drought tolerant plants to help prevent further damage from the El Niño effects.
Why are El Niño events more frequent than La Niña?
As the event develops, the warmed waters cause the winds to weaken even further, which can cause the waters to warm even more. El Niño is often (but not always) followed by La Niña the following year, particularly if the El Niño is strong. Stronger winds push surface water into the western Pacific.
What causes La Nina to surface?
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.
Is El Nino or La Nina worse?
A La Nina usually means a more active season with more and perhaps stronger storms. An El Nino means fewer, weaker storms.
What does La Nina mean for hurricane season?
La Niña is when the surface of the tropical Pacific Ocean turns colder than normal. You might think La Niña’s cooler water near the Equator wouldn’t have an effect on Atlantic hurricanes. A La Niña can have an influence on the entire tropical wind flow and storm steering currents.
How can farmers protect their living from the effects of El Niño and La Niña?
By protecting soil and water you protect crops. Soil that is covered will absorb more water. You can keep soil covered with a cover crop. Cover crops are plants that farmers grow especially to cover and protect the soil.
What are the signs of La Nina?
Watching out for events The first signs of an emerging El Niño or La Niña event are often observed in the ocean. The Bureau of Meteorology monitors and reports on a range of ENSO indicators, including: short-term bursts of tropical rainfall activity. water temperatures at the sea surface and at depth.
How do El Niño and La Niña affect climate?
El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. By modifying the jet streams, El Niño and La Niña can affect temperature and precipitation across the United States and other parts of the world.
