Why is it colder in winter in Shanghai than in the north?

Shanghai has a maritime climate with high air humidity. At the same temperature, you will feel that Shanghai is colder. But this is not the main reason, and it will not lead to colder winter in Shanghai than in Northeast China.

The most important thing is that there is no heating in Shanghai in winter, because the state does not subsidize the cost of heating in winter.

In the early days of liberation, because the country was in an extremely difficult economic period at that time, it was stipulated that there would be no heating in winter south of Huaihe River and no heating subsidies would be issued. In view of the fact that everyone's wages were low at that time and coal was rationed. In this way, not only can we not afford the heating bill, but even if a few people can afford it, we can't buy fuel.

Shanghai has been wintering like this for a long time and everyone is used to it.

In fact, it can be seen from the old houses left before liberation that there are fireplaces and chimneys in the houses. In the past, the rich still kept warm by fire in winter.

Now everyone's economic conditions are better than before, and most people have installed air conditioning.

But the electricity bill is still relatively expensive, and most low-income people still can't afford it. So there are not many days to turn on the air conditioner, and the air conditioner is only used in the coldest time.

In the north, such as Beijing, they started central heating from the end of 165438+ 10 until the following spring.

The indoor temperature is controlled at 18 degrees. Heating is everywhere in homes, schools, shops, institutions and factories. So everyone feels very warm.

But Shanghai is different. The outdoor temperature is only MINUS 2 ~ 3 degrees, and the indoor temperature is only 4 ~ 5 degrees.

Some rooms facing north are even below zero at night. In the dormitory where I used to live, the towels hanging in the room were frozen. Of course, you will feel cold.
