El Ni o Explained in English, El Ni o Explained

The Holy Child is his interpretation.

El Niño, also known as El Niño Current, is a climate phenomenon caused by the eastward movement of the Walker Circulation Circle after the interaction between the ocean and the atmosphere over a large area of the Pacific Equatorial Belt. The basic feature of El Niño is an abnormally high sea surface water temperature along the Pacific coast, a sea level**, and the formation of a warm current that flows southward. It has turned the waters of the eastern Pacific Ocean, which were previously cold waters, into warm waters, resulting in tsunamis and storms, resulting in drought in some areas and excessive rainfall in others.

El Niño has a serious impact on our climate. First of all, the number of typhoons has decreased, and after the occurrence of the El Niño phenomenon, the number of tropical storms (typhoons) in the northwest Pacific and the number of landfalls along the coast of China are lower than in normal years.

Usually in the year of El Niño, China's summer monsoon is weak, the monsoon is southerly, located in the central part of China or south of the Yangtze River, and the northern region of China is often prone to drought and high temperature in summer. After the strong El Niño in 1997, drought and high temperatures in northern China were very obvious.

The third is that the southern part of our country is prone to low temperature and floods, and in the year after the occurrence of the El Niño phenomenon, in the southern part of our country, including the Yangtze River basin and the Jiangnan region, it is prone to floods, and the severe floods that have occurred in our country in the past 100 years, such as 1931, 1954 and 1998, all occurred in the following year of the El Niño year. In 1998, El Niño was one of the most important factors influencing the devastating floods that struck our country.

Finally, in the winter after the occurrence of El Niño, the northern part of China is prone to warm winters. (I only speak Chinese, sorry.) ）

The El Niño phenomenon, also known as the Holy Child phenomenon, is a term used by fishermen in Peru and Ecuador to refer to an anomalous weather phenomenon, and together with another phenomenon, the Southern Oscillation, it is called ENSO. El Niño is a climate phenomenon that occurs when the SST anomaly warms in the tropical Pacific Ocean, and the warming of the tropical Pacific Ocean on a large scale causes global climate change.

1. Introduction to the Nilno phenomenon:

El Niño is a climate phenomenon that occurs when the SST anomaly warms in the tropical Pacific Ocean, and the warming of the tropical Pacific Ocean on a large scale causes global climate change.

El Niño is an anomalous natural phenomenon in the Pacific Ocean. On the west coast of South America and the eastern part of the South Pacific, there is a famous Peruvian cold current flowing from south to north, and from November to March of the following year is the summer of the southern hemisphere, the water temperature in the southern hemisphere generally rises, and the equatorial warm current flowing westward is strengthened.

At this time, the global pressure and wind belts moved southward, and the northeast trade winds crossed the equator and were squeezed to the south by the self-deflection force, also known as the geostrophic deflection force, and deflected to the left into the northwest monsoon.

The northwest monsoon not only weakens the offshore southeast trade winds on the west coast of Peru and weakens or even disappears the cold water flood of Peru, but also blows the warm equatorial current with higher water temperature southward, causing the water temperature of the cold current in Peru to rise abnormally. This quiet and irregular ocean current is known as the El Niño Current.

2. Weather phenomena:

The upwelling cold sea water is rich in nutrients, which makes plankton multiply, provides sufficient food for fish, and the abundance of fish provides abundant food for fish-fed birds, so there are many birds. When the southeast trade wind is abnormally strengthened, the sea water in the eastern equatorial Pacific Ocean rises abnormally strongly and the precipitation is abnormally low, while the sea temperature in the western equatorial Pacific Ocean is abnormally high and the precipitation is abnormally high.

Due to the high sea temperature, unstable air stratification and convection development, the east coast of the equatorial Pacific Ocean changed from dry and rainy to rainy, causing floods, while the west coast of the equatorial Pacific changed from humid and rainy to dry and rainy due to low sea temperature and stable air stratification.

When El Niño occurs, it will cause continuous low temperatures in the Japanese archipelago and northeastern parts of China in summer, and in some years, precipitation tends to be low in most parts of China.

El Niño phenomenon

El Niño, also known as El Niño currents, is a large area of ocean and atmosphere interaction in the equatorial zone of the Pacific Ocean.

A climatic phenomenon that occurs when the balance is out of balance. Under normal conditions, the monsoon ocean in the tropical Pacific region.

The current travels from the Americas to Asia, keeping the Pacific surface warm and bringing tropical rainfall around Indonesia. But this.

This pattern is disrupted every 2-7 years, reversing the direction of the wind and ocean currents, and shifting the heat flow in the surface of the Pacific Ocean.

The eastward movement towards the Americas brings with it tropical rainfall, the so-called "El Niño".La Niña

La Niña is in Spanish"La Nina – "little girl, holy woman" – is the inverse of El Niño, a phenomenon in which water temperatures in the eastern Pacific Ocean near the equator drop unusually, manifested by a marked cooling of the eastern Pacific Ocean, accompanied by global climate chaos, which always follows El Niño.

Meteorologists and oceanographers specifically refer to the occurrence of a widespread and persistent anomalous cooling of the waters of the eastern and central equatorial Pacific (sea surface temperatures below the climatological average for more than six months).La Niña is also known as the anti-El Niño.

Generally, La Niña occurs with El Niño, and the second year of El Niño occurs, La Niña occurs, and sometimes La Niña lasts for two or three years. Strong La Niña events occurred in 1988-1989 and 1998-2001, resulting in cooler than normal sea temperatures from the eastern to central Pacific Ocean and weaker La Niña events from 1995 to 1996. Some scientists believe that La Niña has a tendency to weaken due to global warming.

El Niño is a climatic phenomenon in the Pacific Ocean where the temperature of the sea near the equator rises abnormally. This phenomenon often has a significant impact on the global climate, including rainfall, floods, droughts, storms, etc.

In addition to the name "El Niño", it also has a sign called the "El Niño-Southern Oscillation (ENSO)". ENSO is a combination of El Niño and another climatic phenomenon, the Southern Oscillation. The Southern Oscillation is a guide to anomalous changes in sea temperature in the Atlantic and Indian Oceans.

El Niño events typically occur every 2-7 years, and the entire process usually lasts anywhere from 9 months to 2 years. In the process, sea temperatures rise near the equator, while the eastern Pacific region is drier. This phenomenon has a significant impact on global climate change, especially on agriculture and fisheries in the tropics.

In conclusion, El Niño is an important climate phenomenon that can have an important impact on global climate change. Although its name may be unfamiliar, its influence is everywhere.

El Niño phenomenon generally refers to the El Niño warm current, which is a natural phenomenon in the Pacific Ocean, which flows from south to north on the west coast of South America and the eastern part of the South Pacific Ocean. At this time, the global pressure and wind belts move southward, and the northeast trade winds cross the equator and are deflected to the left by the self-deflecting forces of the southern hemisphere and to the northwest. The northwest monsoon not only weakens the offshore southeast trade winds on the west coast of Peru and weakens or even disappears the cold water flood of Peru, but also blows the warm equatorial current with higher water temperature southward, causing the water temperature of the cold current in Peru to rise abnormally.

This quiet, irregular ocean current is known as the "El Niño Current".

El Niño is further divided into El Niño and El Niño events. El Niño is a climatic phenomenon that occurs in the tropical Pacific Ocean SST anomalous warming, and the large-scale warming of the tropical Pacific Ocean will cause global climate changes, but this state must be maintained for more than 3 months before Zebi is considered to have truly occurred El Niño event. In the aftermath of El Niño, La Niña sometimes follows its predecessors.

El Niño refers to:Anomalous warming of sea water temperature in the eastern equatorial Pacific Ocean over a wide range, over a long period of time, and at different intervals。However, El NiñoThe cause of this is still inconclusive。There are three main points of view:

One is that El Niño is caused by periodic changes in the atmosphere or ocean movements; Second, it is believed that there is a certain correspondence between the El Niño phenomenon and the change of the earth's rotation speed. It is believed that the El Niño phenomenon is related to the activity of the Pacific seafloor crust, such as volcanoes and **. In addition, it has been pointed out that the El Niño phenomenon is related to the greenhouse effect.

The most common view of the causes of El Niño

Under normal conditions, the region near the equator in the Northern Hemisphere is the northeast trade wind, while the region near the equator in the Southern Hemisphere is the southeast trade wind. The trade winds drive the flow of seawater, so that the seawater flowing from the eastern Pacific Ocean in the equatorial region can be replenished by the rise of the lower layer of cold seawater, so that the temperature of the upper layer of the sea water in this area is lower than that of the surrounding area, forming a sea temperature difference between the east and the west.

However, if the southeast trade winds weaken, the flow of seawater will be slowed down or even suspended, and the deep cold seawater will not be able to upwell, so the surface sea temperature in this area will rise, resulting in a wide range of abnormal warming of sea water temperature. The warmer current then moves south along the coast of Ecuador, where cold-water fish are dying in large numbers due to the high temperatures. As a result, fish in fishing grounds die in large numbers, and at the same time, the economies of coastal countries suffer huge losses.

El Niño is a type of hairAn anomaly that occurs in tropical oceans.

El Niño is a term used by fishermen in Peru and Ecuador to refer to an anomalous weather phenomenon. It refers mainly to the unusually continuous warming of sea temperatures in the tropical oceans of the eastern and central Pacific Oceans, which has caused changes in the climate patterns of the world as a whole, resulting in drought in some areas and excessive rainfall in others.

On the west coast of South America, in the eastern part of the South Pacific Ocean, there is a famous Peruvian cold snap that flows from south to north. The Southern Hemisphere summer season runs from October to March. Water temperatures in the southern hemisphere are generally warm.

The easterly equatorial countercurrent strengthens at a time when the global pressure and wind bands move southward and northeast trade winds cross the equator.

Affected by the rotational deflection force of the Southern Hemisphere, it deflects to the left into the northwest monsoon. The northwest monsoon not only weakens the southeast trade wind, which is a bright and blue wind from the west coast of Peru, weakens the cold water of Peru and disappears, but also blows the high equatorial countercurrent water southward in the direction of the Peruvian cold current, transforming the Peruvian cold current into a warm current.

This unstable current is known as the El Niño Current. Usually this "uninvited guest" disappears with the key after March each year as the water temperature on the west coast of South America gradually cools.

The impact of El Niño

1. El Niño affects the global climate.

In the Pacific region, the rainy areas in the western tropical Pacific region have moved eastward with the change of ocean temperature, which has directly led to drought in Indonesia, Australia, and India, and abnormally heavy rainfall in the Pacific rim countries of the Central Pacific and South America, and even caused floods and other disasters. El Niño not only alters the atmosphere over the entire tropical Pacific Ocean, but also affects other parts of the tropics, and even causes climate anomalies outside the tropics.

2. El Niño has an impact on agriculture.

Most El Niño weather will affect the production of agricultural products such as sugar, rice, corn, and natural rubber, thus driving ****.

3. El Niño affects the survival of marine life.

When El Niño occurs, the upwelling currents along the coast of South America weaken and are unable to bring the nutrient-rich cold water of the underocean to the surface, severely disrupting the normal food chain, greatly reducing plankton and depriving many fish of their food.
