Guangdong is hit by typhoons and cold air. What are the differences between the cold in the south and the cold in the north?

Affected by a new wave of cold air and typhoons, coastal cities and counties in Guangdong experienced showers and local heavy rains. The daily average temperature dropped by 3 to 5 degrees Celsius. The temperature dropped by about the same amount as last time, but the wind It will be stronger than last time, and the body will feel cooler than last time. There will be a significant increase in rain. Friends from Guangdong, remember to add more clothes when going out.

Many friends from the south cannot understand the coldness in the north, and friends from the north cannot understand the coldness in the south. There is a difference between the coldness in the south and the coldness in the north. Let me introduce it to you. What's the difference.

1. Humidity is different. In the south, the air has high moisture content and high air humidity, which is called cold and humid. In the north, the air has less water content and low humidity, which is called dry and cold.

2. The perceived temperature is different. The perceived temperature in the south is lower than that in the north. The perceived temperature is usually affected by factors such as humidity, wind, and light intensity. Under the same temperature environment, people who spend the winter in the South will feel that no matter how thick they wear, it will still be bitingly cold. This is because the humidity in the South is high and the thermal insulation ability is relatively poor, while the humidity in the North is low, and the dry air itself has better thermal insulation capabilities. , so the south will feel colder than the north.

3. Heating measures are different. When the weather is cold in the north, they rely on floor heating, heating, etc., while in the south there is no floor heating or heating, and they can only be heated by electric heating, air conditioning, etc.

Every winter, friends from the South and Peking University will start a new round of colder comparisons. People in the South feel that it is not cold because of the heating in the North, while people in the North feel that the South is also like the warmth of spring at this time. The south does not understand the coldness of the north, and the north does not understand the coldness of the south. In the north, if you go out without a hat, you will find that your ears don’t seem to be your own.

Although it is really cold outside in the north, every northerner has a winter artifact. Even if it freezes like a popsicle outside, once you enter the house, it will be heaven. It's different in the south. It's cold outside and even colder when you get home. It's said that there are three difficulties in the south in winter: it's hard to get up, take a shower, and go to the toilet.
