Paris, France is about 48 degrees north latitude, Paris in winter is like this, the snow is a bit “gentle”;
Further north, London, England is located at about 51 degrees north latitude, this is the case in winter;
Continue north, Finland Helsinki is located at 60 degrees north latitude, this is the case in winter;
Harbin, China, located at 46 degrees north latitude, is like this in winter. It is covered by thick ice and snow and looks obviously colder than the above three.
In fact, although Harbin is lower than Paris, London, and Helsinki, it is actually much colder than the three – the average temperature in January is nearly 15 degrees lower!
There is also a more obvious contrast, China’s extremely cold Mohe, located at about 52 degrees north latitude, the temperature in winter is close to minus 30 degrees, while the lowest temperature in the same latitude of Liverpool in the UK is above 0 °C, the port is not frozen all year round, with Hangzhou, China, The temperature in Changsha is similar.
This reflects a geographical knowledge: China is the coldest country in the world at the same latitude. The average temperature of each point on the global latitude is called the average temperature of the latitude. The average temperature in the northeastern China latitude circle is about 14-18 °C lower; the middle and lower reaches of the Yellow River are 10-14 °C lower; the south of the Yangtze River is 8 °C lower; even the coastal areas of South China are about 5 °C lower.
Why is there such a big difference?
Most of the cold air invading China comes from the Arctic Ocean, and then it is strengthened by the cold Siberia. Under the guidance of the northwest airflow at high altitude, the cold wave will burst and accumulate into China, making China’s temperature lower than that of the same latitude.
