China Weather Network News The strongest cold wave this winter is affecting China, the central and eastern parts of the country have encountered a wide range of rain and snow, cooling weather, North China, Huanghuai or the same period of rare cold. Isn't it that this year may be the warmest year in history, so you don't have to worry about getting cold?There is also a phenomenon of thunder while snowing in many places in Henan, is this a sign of disaster?8 winter trivia that many people don't know, let's take a look at a few you've heard.
1.Look, Siberian cold air invades!
Truth: That's not cold air!
Cold air is essentially a relatively cool, dry cold air mass that is not so obvious as white fog. The "cold air invasion" taken by netizens is actually just a cloud coming down from the mountain. This kind of cloud is also called cloud waterfall, and its appearance is also related to cold air in most cases, but it cannot be directly regarded as cold air itself.
2.This year may be the warmest year in history, so don't worry about getting cold?
Truth: It's cold and it's cold.
A few days ago, the National Climate Center** said that 2023 could be the warmest year on record as El Niño progresses. However, this does not mean that there will be no cold air activity in winter, and there will be no extreme cold events. Looking forward to this winter, the temperature in most parts of China is close to the same period of the year or high, but there will still be periods of cold air active.
3.Thunder on a snowy day is a harbinger of disaster
Truth: Rare, but not anomalous.
In fact, thunder can occur in any season, and although "thunder and snow" are rare, they are not particularly abnormal. In autumn and winter, when the strong warm and humid air flow meets the strong cold air, the warm and humid air is forced to rise, producing strong convection, which creates conditions for the formation of thunder and lightning.
4.The sea is "boiling" in winter?
Truth: It's fog.
In winter, the phenomenon of smoke emitting from the sea is often the case, and it looks like the sea is boiling, and this phenomenon is called "Haihao" in folklore. When cold air is much cooler than the sea water passes over the warm sea surface, the water vapor quickly condenses into tiny water droplets and floats on the sea surface to form fog, which looks like the sea is smoking.
5. ufo？！The Earth Engine was activated?
Truth: It's a lamppost on a cold night!
I'm sorry, but science fiction is still a long way from becoming reality. This is actually an atmospheric optical phenomenon, a lamppost on a cold night. When the weather is in a calm state and cold enough, a large number of ice crystals will be formed in the air, and the entire atmosphere will become a "mirror" like existence, and the lights of the city on the ground will be reflected, forming a sci-fi "lamppost" spectacle.
6.Can you freeze the virus to death when it snows?
Truth: Too naïve.
Snow has both pros and cons for the spread of the virus. On the one hand, snowflakes are effective at settling suspended fine particles with viruses or bacteria in the air, so the air quality after snowfall is usually goodOn the other hand, many viruses prefer cold and dry air, and when the temperature drops after snow, the mucous membranes of the human respiratory system are more likely to be damaged, and viruses entering the nasal cavity will have a greater probability of infecting cells, but are more likely to make people sick.
7.Wearing autumn pants will lose people's cold-resistant genes
Truth: It's weird!
There has been a rumor circulating on the Internet that wearing autumn pants will weaken the "cold resistance gene". In fact, among the more than 20,000 genes known in human genetic research, there is no so-called "cold-resistant gene" at all, and not wearing autumn pants is only a training of an individual's cold-resistant ability, which cannot be passed on to the next generation, nor can it represent the cold-resistant ability of the group.
8.Hair loss is more likely in autumn and winter?
Truth: All seasons drop!
The essence of hair loss is the atrophy and degeneration of hair follicles, and the atrophied and degenerated hair follicles do not participate in the body's circulation, unable to absorb the nutrients of the surrounding scalp, and the hair will naturally no longer grow. At present, several common types of hair loss, such as seborrheic alopecia, neuropathic alopecia, chemical alopecia, physical alopecia, etc., have not been scientifically verified by their direct relationship with seasonal changes.
