Global climate patterns will change, what can we do if a Super El Ni o comes?

El Niño often brings to mind extreme, unusual weather features that can have a huge impact on our lives. The El Niño phenomenon will bring a warm winter climate to China. The scarcity of winter snowfall in recent years is the best example of this.

Many people miss the sight of goose snow flying at a young age. But now that climate change is reshaping the evolution and intensity of El Niño, scientists are finding that there could be more "super El Niño" events in the future.

El Niño will lead to unusually high winter temperatures, with cold summers in the Northeast and high temperatures and drought in the north. Because of the emergence of extreme weather, we must take certain precautions, which can be divided into two aspectsOn the one hand, it is to avoid the further deterioration and expansion of the El Niño phenomenon, which is actually related to our daily life habits, which also reflects how important it is to protect the environment.

We should pay attention to the fact that high-level entrepreneurs and leaders should pay attention to environmental protection while earning their own money to promote economic development! The second is if the Super El Niño comesNature is accompanied by a harsh climate, whether it is travel or daily life, you must pay attention to bad weather, avoid dangerous buildings, telephone poles, etc., to ensure your personal safety.

The earth will change accordingly because of people, which makes no difference to the world, any region causes pollution and harm to the environment, and ultimately destroys the entire human group. From now on, we need to put an end to or slow down the super El Niño, so that it will not come to us so soon.

In front of nature, we can do nothing but wait for it to come.

Don't worry, our generation won't see this picture.

It's not so cold in winter, I hope so, it's too cold to be heated.

If the Super El Niño comes to us, we humans are helpless.

It is estimated that it is now a super El Niño, because it is not a yellow plum day even though it is winter, and it is very humid at home for three days without reason!

Wait! Accept! What can be done?

The cycle between the warm El Niño and the cold La Niña in the Eastern Pacific has been going on and on for the past 11,000 years. And this may change in the future.

Using the power of one of South Korea's fastest supercomputers (ALEPH), a team of researchers from South Korea and the United States has created a global climate simulation model. It took more than a year of continuous operation to complete a series of century-long simulations covering today's climate and two different levels of global warming.

It was found that increasing CO2 concentrations weakened El Niño and La Niña climate phenomena. Future El Niño events will lose heat to the atmosphere more quickly due to the evaporation of water vapor. There is a tendency for the oceans to cool down and cover the oaks.

In addition, the future narrowing of the temperature difference between the eastern and western tropical Pacific will also inhibit the development of these two weather phenomena.

Future El Niño and La Niña weather phenomena may no longer be global events.

We don't yet know about the potential ecological consequences of climate change.

Effect.

1. Warm winter. In winter, the Asian continent is controlled by the strong Siberian cold high pressure, and the ocean is relatively much warmer, the air pressure is relatively low, the air flows from the high pressure part to the low pressure part, from the continent to the ocean, so most of our country prevails from the high latitude of the northwest air flow, there are often cold waves and cold air weather transit, the climate is cold and dry. The strength of the winter monsoon is the direct cause of the cold and warm winter in China. The results show that in the winter of El Niño years, the location of the East Asian polar front is often more northerly than normal, and the cold air activity is also northerly and weaker, while the warm air mass in the south is relatively stronger.

Effect. 2. Droughts and floods.

In the summer of El Niño year, the intensity of the Pacific subtropical high increased due to the increase in the sea surface temperature in the eastern equatorial Pacific Ocean and the strengthening of the Hadley circulation. However, the decrease in SST and the weakening of atmospheric convective activity in the western Pacific Ocean have caused the location of the subtropical high to move southward. Studies have shown that the response to El Niño is several months behind the response of the Western Pacific Subtropical High, so the correlation tends to be more pronounced in the second year of El Niño. In addition, due to the influence of the circulation situation, the cold air activity is relatively southerly, coupled with the weak summer monsoon, the northward strength of the warm and humid air flow is not strong, so the monsoon rain belt generated by the convergence of cold and warm air is also southerly, resulting in heavy rain and floods in the middle and lower reaches of the Yangtze River, and little rain and drought in the Yellow River and North China.

In addition, the study shows that in the autumn and winter of El Niño, the eastern part of China is prone to the distribution pattern of precipitation with less in the north and more in the south. That is, the precipitation in most parts of the north is less than normal, and the precipitation in most parts of the south is more than normal.

Effect. 3. Cold summer in the Northeast.

El Niño also has a certain relationship with the summer temperature in northeast China. Statistics show that in the summer of El Niño years, the cold air activity in Northeast China tends to intensify, resulting in abnormally low summer temperatures and low temperature cold damage in Northeast China, resulting in reduced grain production.

Effect. Fourth, tropical storms are on the low side.

Most of the tropical cyclones in the northwest Pacific are developed by low clouds or clouds in the intertropical convergence zone, and when the eastern equatorial Pacific warms in El Niño years, the tropical northwest Pacific becomes cooler and the atmospheric stability increases, which is not conducive to the development of cumulus convection in the tropical Pacific region, and the number of tropical storms and typhoons will decrease accordingly, and the number of landfall in China will be less than normal.

Affected by the El Niño event, the meteorological year in China in the 2015 flood season is moderately deviated, the precipitation in China is generally high, and the Yangtze River basin may have serious flood disasters, and the situation of flood prevention and drought control is not optimistic. The National Climate Center expects the El Niño event to continue. As a result, this summer, China may experience "floods in the south and drought in the north": the Jianghuai River basin and the south of the Yangtze River may have more precipitation than normal for the same period of the year, and local floods will occur, while the drought in North China will be more severe.

El Niño "is a strong warm ocean current, and scientific analysis will lead to a rise in the global climate." （）

a.That's right. b.Wrong orange block.

Correct answer: B

El Niño generally refers to a climate phenomenon in which the interaction between the ocean and the atmosphere in the equatorial Pacific Ocean results in anomalous changes in sea surface temperature over several years. This phenomenon is dominated by widespread warm water currents and has a wide-ranging impact on the global climate.

Specifically, El Niño typically causes the following effects:

2.Impact of Tropical Storm Formation: El Niño can affect the tropical atmospheric circulation, which can have an impact on the formation and path of tropical storms around the world.

3.Rising global temperatures: El Niño causes higher sea surface temperatures in the equatorial Pacific Ocean, often accompanied by higher global temperatures.

4.Ecosystem impacts: El Niño can also lead to ecosystem changes, such as the impact on fishery resources, the transfer of wildlife habitats, and so on.

In conclusion, El Niño plays an important role in the global climate, and people need to pay close attention to its development and impact, as well as to warn of risks and take corresponding measures to minimize the adverse effects of climate change on us.

El Niño refers to a natural phenomenon in the tropical Pacific Ocean in which the temperature of the sea is abnormally high. Under normal conditions, the waters of the eastern tropical Pacific are warmer than those of the western Pacific Ocean, because the direct radiation of the sun causes the eastern waters to be heated. El Niño, on the other hand, alters this climate pattern, causing sea temperatures to rise in the western Pacific and cooler in the eastern Pacific.

This phenomenon can lead to global climate anomalies, such as extreme weather events such as floods or droughts.

As for whether this year will be the hottest year in history, more observations and academic research are needed before the group can draw a conclusion. Current data shows that despite the generally high temperatures this year, there are still some uncertainties. Therefore, we need to wait for more accurate climate data from relevant organizations to make more accurate data.
