Many cities have turned on the high temperature mode, what is the high temperature weather?

Hot weather refers to the weather when the temperature reaches 35 degrees or more.

Every summer, many areas have continuous hot weather. However, in the process of facing this continuous hot weather, many people will have a feeling of not being able to adapt. At the same time, it will also cool down by reducing the number of times you go out, after all, the temperature is relatively high, which can cause people to feel uncomfortable.

Many cities have turned on the high temperature mode.

First of all, since the summer solstice, many places across the country have turned on the high temperature mode. Among them, Hebei and Shandong, as well as Beijing, have successively issued high temperature warning signals. And according to the Meteorological Department**, there will be relatively high temperatures across the country this summer.

In other words, there will be high temperatures in most areas. Therefore, in this case, many people feel that this summer will be particularly hot. <>

What is a hot day?

The second is our definition of hot weather, which refers to the weather above 35 degrees for several consecutive days. And when the temperature reaches 35 degrees or more, it basically makes people feel very hot. Traveling in this kind of weather can make you sweat all over.

So when the temperature reaches 35 degrees or more, most people will go out less often. And they will choose to turn on the air conditioner at home to cool off the heat, and through this way of getting along, everyone can have a better teaching effect. <>

Each and every one of us should take care of the heat.

Finally, I personally think that each of us should pay attention to the way we escape the heat in the process of running our lives. Because only through a reasonable way to escape the heat can you have a cooling effect. For example, in the case of continuous high temperatures, we should choose to turn on the air conditioner at home, and we should also eat more fresh fruits and replenish water at the same time.

In this way, you can have a reasonable cooling state and prevent your body from getting sick due to the heat.

Many cities have turned on the high temperature mode, what is the high temperature weather? High temperature weather is a very high temperature, generally more than 35 degrees can be called high temperature, the performance of hot weather.

Generally, if the temperature exceeds 39 degrees or more, then it is a hot weather, and now many cities in Henan, for example, have encountered high temperature warnings.

Even for many days in a row, the daily temperature is around 40 degrees, the surface temperature is particularly high, and the heat wave in the air can also make people feel uncomfortable.

The world is ravaged by hot weather, and hot weather has the following impact on our lives, first of all, hot weather will affect people's bodies and make people feel unwell. Secondly, hot weather can have an impact on people's psychology, making them feel irritable and depressed. In addition, hot weather can also have an impact on people's production activities, such as agriculture.

Every summer, people will face a wave of hot weather abuse, in recent days hot weather raging around the world, many people said that they can't stand it, the weather is too hot, it's like a sauna, and the outdoor temperature is even as high as 40 degrees. In the face of such fierce high temperatures, people's lives have also been affected.

First of all, hot weather can have an impact on people's bodies. The first thing that the hot weather affects is people's body, many people have heat stroke in the high temperature, feeling unwell, especially some elderly people, because the high temperature induces some diseases, such as cardiovascular disease, heart disease, etc., and some people have a hot cold, or even a stroke, as well as diarrhea symptoms. In conclusion, at high temperatures, people's bodies experience a lot of discomfort.

Secondly, hot weather can have an impact on people's psychology. In addition to the physical effects, there are also psychological effects, and many people become very irritable emotionally. Because high temperature may affect the emotion regulation center of the human hypothalamus, there will be emotional disorders, coupled with sweating, the body's metabolism will also be impaired, and it will also affect the neural activity of the brain, so it is normal to have abnormal emotions.

It is recommended that everyone regulate their emotions more and calm their minds naturally cool.

In addition, hot weather will also affect people's production activities. The impact on productive activities includes the impact on work, such as agriculture and industry. Because of the hot weather, it has brought a big blow to agriculture, and the high temperature evaporation, resulting in a decrease in soil moisture, and crops are also affected.

There are also some people who need to work outdoors, and the hot weather also brings a certain degree of inconvenience to their work.

The above are the various effects of hot weather on people's lives.

Clause. First, it is inconvenient to travel, and the hot weather is very hot no matter where we go, which will hinder us from going out to play or work. Clause.

Second, it is inconvenient in daily life, because the weather is hot, and you are sweating when you go out to eat or walk, and you have to take a shower several times a day on average, otherwise you are embarrassed to go out with a smelly body.

It has seriously affected our normal travel. And it may cause us heat stroke, it can also cause us to get sick, it will cause us to sunburn and it will also lead to allergies, and it will lead to ultraviolet allergies, which has seriously affected our living conditions, and has also led to electricity consumption at home.

It will affect the body, feel uncomfortable, heat stroke and irritability, and it will also be particularly depressed, which will affect agriculture and reduce crop yields.

The hot weather can make us feel too hot to go outside and have to stay at home.

High temperature weather mainly comes from global warming, and long-term continuous high temperature weather will have a great impact on the world. The first will lead to a rise in the Earth's sea level; second, it will cause various disaster weather; Thirdly, the Earth's ecosystems will find change; Fourth, it will accelerate the plundering of resources between regions.

Sea level rises. According to scientists' research and calculations, as the temperature gradually rises, the glaciers in the Antarctic and the Arctic have begun to melt, when the glaciers in the polar regions have all melted. The sea level will rise by 60 meters, and the Earth's land area will be reduced by 60 percent.

At this time, the living space of animals, plants and humans on land will be greatly compressed.

Disaster weather is frequent. Rising temperatures can lead to extreme conditions in the flow of air, which can lead to frequent natural disasters such as droughts, fires, tornadoes, typhoons, heavy rains, and hurricanes. When the snow and ice melt in the mountains and rivers on land, especially the permafrost, a large amount of snow water enters the rivers, causing flooding.

Freshwater resources will be severely affected. In addition, the continental shelf is also frequently hit by tsunamis, and humans have to migrate inland.

Changes in ecosystems. At the same time, the heat of the air increases, the earth cannot dissipate the heat, and the rising temperature will cause the plants on land and the algae plants in the ocean to grow wildly. The growth of plants will inevitably lead to an increase in photosynthesis, and the content of the air on the planet will change dramatically.

There have been times in the history of the earth when there was a high level of oxygen in the air. At this time, the size of the earth's plants and insects was very large. There is a good chance that mammals will disappear from the earth.

In addition, the melting of glaciers and snow-capped mountains will accelerate the death and evolution of plants and animals at high altitudes, and the high temperature environment will also lead to the proliferation of bacteria that can wreak havoc in any corner of the planet.

Plundering of finite resources. As the earth's temperature rises, the living space of people and animals will be compressed, and there will be inevitable conflicts and wars between people and people, and between people and animals for food, space and water. Eventually, the earth's ecosystem will be completely broken, and the earth will eventually become uninhabitable.

High temperatures have become the norm and have caused inconvenience to many people. It is indeed difficult to survive outdoors in hot weather, and for everyone, the scorching sun will make your body lose water quickly, which will also cause great problems and threats to yourself. So the weather is so high, it will indeed bring some impact and changes to the world.

Nowadays, many crops have died due to high temperatures, and many plants have been depleted due to high temperatures. It also has a big impact on these animals, so the heat has really changed the flora and fauna around the world. <>

And in the weather that has been in high temperatures, it is very likely that there will be a trend of global warming, which will also undergo some changes in the atmosphere. The temperature is getting higher and higher, and the weather is extreme, and many people feel like they can't breathe well when they're outside. Due to the high humidity in the air and the high temperatures, the atmosphere has changed accordingly, and many ponds and rivers have dried up due to the influence of such temperatures.

The gradual evaporation of water will lead to more and more humidity in our air, which will also have a huge impact on people's breathing. Therefore, not only the impact on animals and plants is huge, but also the impact on human beings is unprecedented. In our lives, we should also pay attention to such situations and try to ensure that our own living conditions are very stable.

Because we all know that if the hot weather continues, it will lead to difficulties in our lives, and it will also affect our work and study for everyone. Too high a temperature will indeed have a very big impact on everyone, so everyone should also pay attention to the impact of such a temperature in life, and if there is such a temperature impact, you need to take corresponding measures to deal with it.

If high temperatures become the norm, the world will be in the process of rising temperatures, which will lead to melting glaciers, rising sea levels, and persistent droughts in isolated areas on land, all of which will have significant global implications.

The first is the reduction in crop yields, which are already at risk to the livelihoods of hundreds of millions of people as famine, water resources change, melting glaciers at the poles, and rising sea levels.

Causes of the formation of hot weather:

1. Solar radiation.

In summer, the direct sun gradually moves from south to north, and on the summer solstice, it hits the Tropic of Cancer directly. In this process, the solar altitude angle in the Northern Hemisphere gradually increases, the sunshine hours continue to increase, the received solar heat gradually increases, and the temperature also increases. This is the basic reason for the formation of hot weather.

2. Atmospheric circulation.

On the one hand, specific circulation situations are prone to high temperatures. A typical example is the subtropical high, which has the title of "high temperature messenger". In the middle of summer, the western Pacific subtropical high controls the middle and lower reaches of the Yangtze River in China, and the air warms strongly due to the prevailing downdraft in the subtropical high.

At the same time, the weather is sunny and cloudless, which is conducive to sunlight, and the ground radiation temperature is significantly warmed, which is easy to form high temperature and hot weather. In addition, weather systems such as continental warm high pressures, tropical cyclones, thermal low pressures, and weak cold fronts will also generate high temperature and heat waves.

On the other hand, atmospheric circulation anomalies also have a direct impact on the formation of high temperature weather. For example, if the position and intensity of the subtropical high are abnormal, it will cause changes in high temperature weather.

3. Geographical factors.

The geographical location, topography, landform and other characteristics of a place also affect the level of temperature. For example, Nanjing, Wuhan and Chongqing, the three major furnace cities that have appeared in China's "history".

They all belong to basin-like terrain, which is easy to store heat and not easy to dissipate heat, which helps to form hot weather. For example, due to the high altitude, some areas such as the Qinghai-Tibet Plateau have not experienced high temperature weather.

4. Global warming.

Due to the influence of human activities and natural fluctuations in the climate, the global average surface temperature has been on an increasing trend for more than 130 years. Over the past few decades, each decade has seen temperatures significantly warmer than the previous one. Under the influence of global warming, extreme heat events are also becoming more frequent.

5. Urban heat island effect.

Due to the dense population and large building area of the city, the humidity and air convection of the urban surface have changed, resulting in a significantly higher temperature in the city than in the surrounding area.

Nowadays, with the acceleration of urbanization, the urban heat island effect is more obvious, which plays a role in the formation of hot weather.

Subtropical high pressure.

The formation of high temperatures is often directly caused by specific weather systems, the most typical and common of which is the subtropical high, which has the title of "high temperature messenger".

From the mouth of the weather forecast host, we often hear commentary such as "With the strengthening of the sub-high, China's Jiangnan, South China and other places will usher in a round of high temperature weather", especially in summer.

High temperature weather is very harmful to the human body, for example, some weak people will suffer from heat stroke or heat stroke. In addition, the temperature is too high, and the water evaporates too much, and it does not rain all the time, so many rivers dry up, and there is no way to generate hydroelectric power. This will cause problems with people's electricity consumption, such as Sichuan Province, which has begun to limit electricity.

Extreme heat can not only be unbearable for the natural world, but also affect people's lives very seriously. Outdoor workers in society have no way to work freely, and they must work in the morning or evening, otherwise the body will be unbearable. There have been a lot of people who have suffered from heat stroke before, and when I went to the hospital, the temperature of the body has reached 42 degrees Celsius, which is simply not able to rely on today's medical technology, which is really a pity.

So if it's too hot, be sure to turn on the air conditioner, don't worry about the electricity bill, and don't let your body be seriously harmed. If you are hospitalized due to heat stroke, it will cost you a lot of money and delay your daily work or life.

In addition to the harm to people, in fact, the harm to the natural world also indirectly acts on people, because people live in the natural world. For example, the so-called reduction in water generation will reduce the amount of electricity generated, which will make the power supply load extremely high in many places, and power outages will occur from time to time. There are many people who have no way to sleep at all when the power goes out, and can only go to the roadside to cool off.

And global high temperatures are also very closely related to global warming, which will make the future development of mankind more confusing. If all the icebergs melted, the sea level would also rise, threatening the survival of coastal countries.

Some experts have analyzed, in fact, this high temperature is somewhat expected, and today's big outbreak is just a real show, and the temperature may get higher and higher in the future, especially in summer.
