What are the positive effects of El Nino?
Positive effects of El Nino: The El Nino event brings few assets. Warmer climate. Many parts of North America have a favorable impact of El Nino. Southern Canada and northern continental United States encounter milder winters. It brings relief to the people in the region, which faces extreme winters. Also, drier weather in these areas means low ...
Which is the initial effect of an El Nino?
What are the effects of El Niño? Primary effects: these are directly caused. Insect population explosion leading to disease and plagues. Fewer hurricanes and other tropical cyclones in the north Atlantic Milder winters in southern Canada and the northern continental United States.
What unusual event occurs during El Nino?
Some normally arid tropical habitats are transformed into virtual gardens during El Niño. Abundant and reliable rains in other tropical areas become sparse and intermittent during El Niño. Extreme climates have also been experienced in the higher latitudes during ENSO, though these are by no means unique to ENSO.
What are the consequences of an El Nino event?
The El Niño event affected millions of people around the world, including in Africa, Central America, Southeast Asia, and the Pacific Islands. These effects included below or above-average rainfall, flooding, increased food insecurity, higher malnutrition rates and devastated livelihoods.
What is El Niño anyway?
El Niño is a condition that sometimes occurs in the Pacific Ocean, but it is so big that it affects weather all over the world.
How do you take the ocean's temperature from space?
Where the ocean is warmer, sea level is slightly higher. In 2008, the Jason-2 satellite (also called the Ocean Surface Topography Mission) was launched into orbit around Earth. It continued the measurements being made by Jason-1, launched in 2001. Both satellites have a sensitive altimeter onboard.
Watch El Niño in action!
Here's a movie that shows the El Niño and La Niña conditions as they occur from December 1996 through January 2000. Watch the white bulge of warm water travel across the Pacific ocean.
What is the term for the oceanic nino index?
Today, most scientists use the terms El Niño and ENSO interchangeably. Scientists use the Oceanic Nino Index (ONI) to measure deviations from normal sea surface temperatures. El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons.
What is the cool phase of ENSO?
La Nina, the “cool phase” of ENSO, is a pattern that describes the unusual cooling of the region’s surface waters. El Niño and La Niña are considered the ocean part of ENSO, while the Southern Oscillation is its atmospheric changes.
What is upwelling in Peru?
Upwelling provides food for a wide variety of marine life, including most major fisheries. Fishing is one of the primary industries of Peru, Ecuador, and Chile. Some of the fisheries include anchovy, sardine, mackerel, shrimp, tuna, and hake. The upwelling process also influences global climate.
What is the name of the ocean that describes the unusual cooling of the region's surface waters?
Vocabulary. El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO). La Nina, the “cool phase” of ENSO, is a pattern that describes the unusual cooling of the region’s surface waters.
What causes the jet stream to move northward and to weaken over the eastern Pacific?
La Niña causes the jet stream to move northward and to weaken over the eastern Pacific. During La Niña winters, the South sees warmer and drier conditions than usual. The North and Canada tend to be wetter and colder.
What causes the Pacific jet stream to move south?
The warmer waters cause the Pacific jet stream to move south of its neutral position. With this shift, areas in the northern U.S. and Canada are dryer and warmer than usual. But in the U.S. Gulf Coast and Southeast, these periods are wetter than usual and have increased flooding. El Niño causes the Pacific jet stream ...
What causes the jet stream to move south and spread further east?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North.
How does El Nino affect the world?
El Nino Effects. El Nino results in the rise of sea surface temperatures. It also weakens the trade winds of the affected region. In India, Australia, it can bring about drought conditions. This affects the crop productivity largely.
How did El Nino get its name?
El Niño is Spanish for “the boy child” and is named after the baby Jesus.
What is El Nino?
El Nino can be understood as a natural phenomenon wherein the ocean temperatures rise especially in parts of the Pacific ocean. It is the nomenclature which is referred to for a periodic development along the coast of Peru. This development is a temporary replacement of the cold current along the coast of Peru. El Nino is a Spanish word.
What is the opposite of El Nino?
Another natural phenomenon, similar to El Nino is La Nina, which is also in news these days. The term La Nina literally means ‘ little girl’. It is termed as opposite to the phenomenon of El Nino as it results in the ‘cooling’ of the ocean water in parts of the Pacific ocean.
How strong is El Nino?
The intensity of El Nino events varies from weak temperature increases (about 4-5° F) with only moderate local effects on weather and climate to very strong increases (14-18° F) associated with worldwide climatic changes.
What do scientists collect about El Nino?
Scientists, governments, and non-governmental organizations (NGOs) collect data about El Nino using a number of technologies such as scientific buoys.
Does El Nino cause drought?
It has been also observed certain times, that EL Nino may not bring drought but cause heavy rainfall. In both the cases, it causes heavy damage. However, in some other countries it may result in a complete reversal, i.e., excessive rainfall.
