I don't know if you have felt a very strange phenomenon recently, after each strong wind cools down, the temperature always takes the opportunity to suddenly rise in temperature, forming a strange phenomenon of a strong rebound in temperature.
For example, the recent period of high winds and cold spells that occurred between December 5 and 7 was very evident.
Around December 5 and 6, they obviously formed a relatively obvious cooling process along the way under the action of strong winds and cold waves, but after the passage of these cold air, they began to warm up rapidly along the way from December 7.
And this phenomenon does not only appear in individual areas, but is a common phenomenon, for example, this time in Zhengzhou, Beijing, Shijiazhuang, Taiyuan, Hohhot, Changchun, Shenyang and other places, all coincidentally, to varying degrees of this temperature rebound phenomenon.
Especially in Zhengzhou, in the process of this wave of warming, there was a high temperature of more than 25.6 °C, which also set a record for the highest temperature in the same period ever.
At the same time, every time in different areas, the stronger the wind, the more obvious the cold wave cooling process, the more intense this phenomenon will also be, forming a very sharp contrast of temperature changes, like a roller coaster, which is thrilling and deeply felt.
So what exactly is the cause of this phenomenon?
Some scholars now conclude that it is caused by a climate phenomenon called "frontal warming", but the frontal warming should occur before the windy cold wave cools down, but the reality is that this warming phenomenon occurs precisely after the winds cool down, so it is obviously not right in time, and they should obviously be a "post-wind" phenomenon (see the two figures below).
Of course, there are more scholars who believe that this phenomenon is caused by the arrival of a large amount of cold air, and the increase in the space extrusion force formed, so since it is caused by the pressurization of cold air, shouldn't it be accompanied by more cold air, and the cooling effect is getting stronger and stronger? Why does the phenomenon of heating increase?

So what is the reason for the occurrence of this rather strange climate phenomenon? Today, we will use the method of internal rotation space theory to talk about this topic.
According to the principle of space transformation effect in the theory of internal rotating space, in a relatively closed space environment, if the internal material space is lost due to various reasons, and the external material space cannot be replenished in time, then a low-pressure space under negative pressure will be formed.
In this way, the various material spaces in this enclosed space will increase their respective spatial ranges due to the decrease of the spatial extrusion force between the material spaces, thus forming a thermal effect and causing the ambient temperature inside the space to rise.
On the contrary, in this relatively closed space environment, if the internal material space increases sharply due to various reasons, and the additional external material space cannot be discharged in time, then a high-pressure space under high pressure will be formed.
During this period, the various material spaces in this enclosed space will increase due to the increase of the spatial squeezing force between the physical spaces, resulting in the reduction of their respective spatial scopes, thus forming a cooling effect and causing the ambient temperature inside the space to decrease.
The same is true when it comes to climate change.
Every time the windy space arrives, along with the squeezing effect of these windy spaces in terms of wind and wind potential, the surrounding material space will also shrink its own space range, forming a cooling effect under the cooling effect.
This change will make you feel the chill every time a strong wind arrives, even if there is no cold air inside.
For example, the hot air that occurs during the summer months, although it contains some hot air, we also have a cooler feeling (of course, it will also include the heat consumption and cooling effect caused by the air movement).
Not to mention that during the winter of each year, along with these winds, there is also a large amount of cold air, so during the arrival of the windy cold wave, under the double cooling effect, the temperature drop around us will also become very drastic, and we will always feel the cold wind.
This phenomenon is especially obvious on the windward side of a mountain or building that is blocked in front of it, because the space squeezing force is relatively large, and the shrinkage of the material space will be more obvious, so the performance will be more obvious.
Therefore, during the winter of each year, with the advent of strong winds and cold waves, the most obvious places to cool down are often the windward side of some mountains, and on the leeward side, the cooling range will be relatively small.
With the departure of these windy cold waves, around the areas it passes through, due to the rapid loss of material space, low pressure space and thermal effects will be formed, resulting in a warming phenomenon.
And around the areas where these strong winds pass, in those places where the geographical environment is relatively open, due to the fast air flow speed, the loss of material space is the easiest, so the temperature rise will be the fastest in the later period, and the temperature difference will change greater. Of course, it is also here that it is easiest to obtain the replenishment of new foreign material space, quickly reach a state of equilibrium, and return to normalcy.
On the contrary, in those relatively closed regional environments, such as in the leeward side of the mountains and some low-lying areas, although it is not easy to cause the loss of material space in the early stage, it is not easy to obtain the supplement of new material space in the later stage, so it will be shown that the cooling range in the early stage is small, but the low temperature duration in the later stage will be relatively long, the temperature difference before and after is relatively small, and the temperature rebound phenomenon is not very obvious.

Therefore, during the period before and after the gale and cold wave, around the road it passes, in the area with greater wind speed, it is often easier to form a very obvious temperature change process, resulting in a very obvious temperature rebound phenomenon.
Especially during the winter of each year, under the paving of the large cooling effect in the early stage, there is often a very obvious temperature contrast between the temperature and the later heating phenomenon, forming a sharp temperature contrast, giving people a roller coaster of retaliatory heating feeling.
