Why do you suddenly feel hot? Do you think this weather is normal?

Why do you suddenly feel hot? It's only May and the weather has soared to 38℃. Is it normal? Yes, from the real-time temperature list of the Central Meteorological Observatory, it can be seen that in May 1 day, the temperatures in Hebei, including Huailai and Xuanhua, all exceeded 37℃, while the temperatures in Hebei Zhuolu exceeded 38℃. Including but not limited to Liaoning, Inner Mongolia and Shanxi, the temperature in some areas also exceeds 36 degrees Celsius. Indeed, high temperature has become the main theme of this holiday.

Of course, in the 24-hour temperature forecast chart of the Central Meteorological Observatory, you can directly see the temperature levels all over the country. Different colors represent the temperature range of their respective places. For example, in some areas of Wuhan, Chengdu and Chongqing, we can directly see that the temperature exceeds 32℃ from the comparison of color and numerical range. Of course, in fact, there were many places with high temperature on May 1 last year, but this time the high temperature and high area seem to be more intense and extensive than in previous years. Therefore, this phenomenon inevitably causes some people to wonder why it is only early May and the weather is already so hot.

First of all, we need to know how the natural phenomenon of weather is formed and why there may be a big weather difference in places not far apart. In fact, whether it is windy, snowy, hail, or humidity, pressure and temperature in a certain place, it is essentially the performance of one of the meteorological elements in a specific space. It is said that the weather is unpredictable. Even if the weather can be predicted at present, the accuracy is still less than 100%. This is because the weather system of the earth itself is in the process of continuous formation and extinction.

For the weather system, there is also the so-called high temperature, which usually means that the maximum temperature in a single day reaches or even exceeds 35℃. When the high temperature weather lasts for more than 3 days, a complete weather process is formed, which is called high temperature heat wave. In fact, during this May Day period, high temperature and heat waves did occur in some areas, but this phenomenon did not surprise meteorologists. Objectively speaking, the frequency of high-temperature heat wave weather is not low in recent years, and in order to avoid disasters caused by high-temperature weather, China has also formulated high-temperature warning signals.

Although the human body has the ability to regulate body temperature, everyone's maximum temperature tolerance is different, especially children and the infirm. Therefore, the necessity of high temperature warning is obvious, which can not only make people prepare for sun protection and cooling in advance, but also effectively avoid more accidents. It is not the first time that the temperature in some areas has exceeded 35℃ during May Day. During this period, some areas also issued a cold wave warning. For example, in the next 48 hours, the temperature in some areas of Heilongjiang Province will drop by 8℃ to 10℃.

In short, it is not surprising that the temperature in some areas exceeds 38℃, and when we bake at high temperature, it does not mean all parts of the country, especially those areas experiencing cold waves. To be sure, it is not surprising that the temperature in some areas exceeds 36 degrees Celsius at some time in May, because such a situation has never happened in previous years. Moreover, even if the temperature in some areas is as high as 38℃ or above, it does not mean that there is no cooler place in all parts of the country. Just like in April, there was a sudden hailstorm in some places, which many people thought was an unnatural weather phenomenon with hidden information.

However, whether it is hail or sunny, it is the result of the weather system carried by the earth itself. Now everyone is concerned about global warming. Of course, there are countless scientists thinking about how to solve this climate problem, which is further aggravated by human beings. However, even if global warming will lead to a slow rise in temperature, it is not necessarily related to sudden high temperature. In the long run, whether the distance between the earth and the sun changes in the process of evolution or human long-term emission of greenhouse gases into the earth's atmosphere, these factors will cause our earth to become hotter and hotter.
