Which is colder, wet and cold in the south or dry and cold in the north?

Lead: As we all know, dryness and coldness are the climatic characteristics in the north of China, while wetness and coldness are the climatic characteristics in the south of China. The southern region and the northern region are cold and have different characteristics, so which is colder, wet cold in the south or dry cold in the north? Is it wet and cold in the south or dry and cold in the north? Let's have a look.

Which is colder, wet and cold in the south or dry and cold in the north?

It is colder in the south. Meteorologists say that the humidity in the south may be better under the same temperature conditions, but in the same season, the temperature in the north is often lower than that in the south.

The temperature often mentioned in the weather forecast represents the temperature of the air. Wind power and relative humidity are two important factors affecting the somatosensory temperature-the greater the wind power, the faster and more heat the human body loses; When the relative humidity rises above 70%, the heat of human body will be transferred to the air, and it will feel colder and colder.

According to the somatosensory temperature formula of the Central Meteorological Observatory, when the temperature is 5℃, if the relative humidity reaches 70%, the somatosensory temperature is only 2.6℃, and if the relative humidity rises to 90%, the somatosensory temperature will drop to 65438 0.2℃. At the temperature of 5℃, the somatosensory temperature will drop to 2.5℃ when the gale of magnitude 7 blows, and it will drop to 1.8℃ when the gale of magnitude 9 blows. In our country, it is common for the air humidity in the south to reach 70% or more in winter, but it is not so easy to maintain a strong wind of 7-9 in the north, so southerners are more likely to feel "cold" under the same temperature conditions. But in the same season, the actual temperature in the north is often much lower than that in the south, and some even as low as 20℃, so the cold in the north can not be underestimated.

The difference between dry cooling and wet cooling lies in the temperature, the influence on the skin, the temperature sense of the human body and so on.

1, temperature: dry and cold means cold weather and dry air; Wet cold means that the weather is cold, but the air is humid.

2, the impact on the skin: dry and cold will make the skin dry; Wet and cold will not make the skin dry, but it will make the skin oily.

3, human body temperature perception: the thermal conductivity of humid air is much greater than that of dry air, and the temperature of human body will be released soon.

The colder the weather, the more you should exercise?

First, burn calories.

It's cold, so the body must consume more calories to maintain its body temperature. In the same environment, relatively speaking, winter consumes more calories than summer.

Moreover, when cold air comes into contact with warm body, exercise heat will also increase, especially in winter, the efficiency of burning fat will increase by about 5%.

For people who want to lose fat, winter is definitely the golden period of losing fat.

Second, it is not easy to ignore warm-up.

The temperature is hot in summer, and many people feel warm. After entering the gym, they begin to exercise directly, often ignoring the importance of warm-up. In fact, it is easy to hurt their bodies.

Warm-up time will also increase in winter, because the temperature is low, people are unwilling to move and their limbs are inflexible. At this time, long-term warm-up can effectively avoid sports injuries.

Third, the immunity is improved.

After winter training accelerates blood circulation, the antibodies in the blood can be improved more effectively, and the immunity and resistance of the body will also be improved.

For people who often suffer from bronchitis or lung infection, persisting in exercise in cold weather can improve the body's resistance.

Fourth, not afraid of the cold.

When the weather is cold, many friends feel that they are too cold to exercise. However, if you keep exercising, you will find that your willpower has been greatly improved, and your body will gradually heat up to keep yourself away from the cold.

What is the coldest place in China?

The coldest place in China is Mohe River in Heilongjiang Province. Mohe is a small village on the Sino-Russian border. The lowest temperature in winter can reach MINUS 30-40 degrees, and the extreme lowest temperature can reach MINUS 50 degrees, which is very cold. In Mohe, the freshly boiled water will freeze immediately when it is poured outdoors. The average temperature in summer is also around several degrees, so Mohe has a small population. At some time in winter, you can also see the beautiful aurora phenomenon.

Mohe county is the lowest temperature county in China, which belongs to the continental monsoon climate of cold temperate zone. Due to the alternating influence of continental monsoon and maritime monsoon, the microclimate is changeable and the local climate is significantly different. Winter is controlled by the polar continental air mass, and the climate is cold, dry and long; In summer, affected by the subtropical ocean air mass, the precipitation is concentrated, the rainfall is abundant, the climate is hot and humid, and the sunshine time is long, which is suitable for the growth of cold-tolerant crops, but it is prone to floods and low temperature chilling injury. In spring and autumn, the climate is changeable due to the alternation of winter and summer monsoon. In spring, there are many strong winds, less precipitation and dry things, which are prone to forest fires; In autumn, the temperature drops suddenly, and early frost and freezing injury often occur.
