Why is it colder in winter in the south than in the north? Why is the south wet and cold?

Lead: China is characterized by hot summer and cold winter. In winter, many people will try their best to keep warm from the cold. I said that winter in southern China is characterized by wet and cold, so why is winter in southern China wet and cold? Why is it colder in winter in the south than in the north?

Why is the winter in the south wet and cold?

The reason why there is wet and cold weather in winter in southern China is because the cold air in the north goes south. The climate in the south is warm. Cold air in the north meets warm air in the south, cold and warm air masses meet, and warm air masses rise to form precipitation. Precipitation is what we usually call rain. After the rain, the humidity in the air increases, the temperature in winter is low and the weather is wet and cold. At the same time, precipitation will also block the sunshine, so the sunshine in wet and cold weather is relatively weak.

The greater the air humidity, the colder the body will feel. In winter, the greater the relative humidity of the air, the easier it is for the human body to dissipate heat, so the human body will feel colder. In fact, wet and cold does not mean that there is more water vapor in the air, but that the air is full of small droplets with a diameter of only a few microns. This small droplet is hard to see with naked eyes, but it is easy to attach to human skin. With the evaporation of water droplets, it takes away the body's heat, which makes the body feel cold.

Wet and cold air is unfriendly to the elderly with weak resistance and children whose bodies are not yet fully developed, and it is easy to cause physical discomfort. When the environmental humidity is too high, the air is easy to breed all kinds of bacteria and viruses. Careless will lead to respiratory diseases such as colds and asthma. Of course, diseases such as rheumatism and arthritis will also increase the incidence.

How to crack the magic attack caused by wet and cold?

In winter, the temperature can be solved by air conditioning and floor heating, and the humidity can be solved by dehumidifier. In order to get clean air, a new dehumidifying fan can be used to solve the problems of wet cooling and air purification simultaneously.

The dehumidification and fresh air integrated machine is supported by the powerful strength of dehumidification, purification and fresh air. The dehumidification capacity is as high as 75 liters per day, which is moisture-proof and odor-proof. It can cope with the wet and cold magic attack, the rainy season in the south and the return of the south more calmly. In the process of dehumidification, fresh air is introduced quickly, and then impurities are intercepted by double-layer high-density filter screen. The purification rate of PM2.5 is as high as 99%. Finally, through the total heat exchange core, the temperature in the air can be recovered, the loss of indoor cold and hot energy can be reduced, the indoor air quality can be effectively improved, and environmental protection and energy saving can be realized.
