What does fog mean?

"Fog City" refers to the British capital "London"

Introduction to London:

London (English: London, pronunciation:? /? l？ nd？ N/) is the capital of the United Kingdom of Great Britain and Northern Ireland, the largest city in Europe and the largest economic and financial center in London. The Romans founded this city more than two thousand years ago. For hundreds of years, London has had a great influence on the world. London, the core area of the city, still maintains the boundaries that have been divided since the Middle Ages. However, at the latest from the19th century, the name "London" also represents the development of the surrounding areas around London. These satellite cities constitute the metropolitan areas of London and Greater London. London is a very diverse metropolis, with residents from all over the world and diverse races, religions and cultures. There are more than 300 languages in this city. At the same time, London is also a world-famous tourist destination with a large number of scenic spots and museums. London is one of the four world-class cities, and the other three are new york, Tokyo and Paris. 180 1 At the beginning of the 20th century, London, as the capital of the British Empire, became the largest city in the world because of its outstanding achievements in the fields of politics, economy, humanities and culture, and scientific and technological inventions. London is the largest economic center in Europe. The financial industry is the most important economic pillar in London.

The reason why it is called "Fog City":

Because every autumn and winter, the west wind blows the water vapor from the Atlantic Ocean to the land. Coupled with the large temperature difference between day and night, the low-level air is cold and condensed, forming a foggy sky.

At the beginning of the 20th century, most Londoners used coal as household fuel, which produced a lot of smoke and dust. 1952 65438+On February 5, London was affected by an anticyclone, the air was in a stable state, and a large amount of waste gas stayed over the city for a long time. Clouds were gathering over London, and soot was falling from the air. Until February 9, 65438, a strong west wind blew it away. It was this "smog incident" that made London completely put on the hat of "Fog Capital".

London population:

About 7 1% of London is white, 1% is of Indian, Bangladeshi or Pakistani descent, 5% is of African black descent, 5% is of Caribbean black descent, 3% is of mixed race, and about1%is of China descent. 58.2% of the population believes in Christianity, and 15.8% of the population has no religious belief. About 2 1.8% of London residents were born outside the EU. Many people still think that Britain is an Anglo-Saxon country, with whites accounting for the vast majority. That was not the case. Guests who come to London for the first time may be surprised by so many blacks and orientals here. As the former capital of the British Empire, London not only received the legacy of the old colonies, but also received a large number of immigrants, resulting in various profound social problems. But on the other hand, it is also one of the conditions for becoming an international metropolis.
