Other foggy cities in the world

London, England

The British capital is also one of the largest metropolitan areas in Europe and one of the four world-class cities in the world. Tied with new york, Paris and Tokyo; It is not only the political center of Britain, but also the headquarters of many national organizations; In addition, there are many scenic spots and museums.

Compared with the foggy days in Chongqing, the annual average foggy days in London are only 94 days. And the causes of its fog are also different from those of Chongqing, and its fog is caused by improper use of fuel in a large area; Since the beginning of the 20th century, local residents in London have used coal as household fuel, and the smog generated, coupled with London's mild maritime climate, has made the air humid, rainy and foggy, especially in autumn and winter, thus forming foggy weather.

At that time, the number of deaths caused by "foggy days" in London was as high as 4,000. Later, the foggy weather in London was improved through a bill introduced by the government.

Edinburgh in England

A city in northern England, the capital of Scotland, the economic and cultural center; Because the local climate is rainy and rainy, it is called "Old Fog Capital" by local people. Throughout the year, only summer weather is good, and other seasons are dominated by rain and snow; Coupled with the influence of maritime climate, winter is very humid and rainy. Compared with London, the foggy days in Edinburgh are a bit more romantic.

Tokyo, Japan

A city in the east of Honshu Island, Japan, the largest city in Asia and the second largest city in the world. As one of the largest economic centers in the world, Tokyo has the most complex, dense and highest volume railway transportation system and commuter station group in the world. Its annual average foggy days are 55 days.

The local area belongs to subtropical monsoon climate with abundant rainfall, which leads to the increase of water vapor in the air. Coupled with the urban heat island effect and air pollution caused by industrial waste gas, there are more and more foggy days in cities. This is the reason for the local fog.

San Francisco, United States

Pacific coast seaport and industrial and commercial city in California, USA; Located at the northern end of the peninsula between the Pacific Ocean and San Francisco Bay, this foggy place is completely different from London. London is not only because of the climate, but also because of industrial pollution and improper use of fuel.

The fog in San Francisco is caused by the intersection of two major ocean currents, which is a natural cause; So it looks more attractive; Among them, "Golden Gate in Fog" attracted many tourists to watch. I don't know if my friends have seen it.

Ankara Turkey

Located in the northwest of Anatolia Plateau in Asia Minor Peninsula, it is the second largest city in Turkey after Istanbul. It is also the center of politics, economy, culture, transportation and trade, and is known as the "heart of Turkey". The cause of Ankara's foggy city is exactly the same as that of London and Tokyo.

It is caused by climate and industrial pollution, so it is inhaled in large quantities in foggy days, leading to various diseases and even death in severe cases; Ankara has about 80 foggy days a year; In winter in Ankara, looking out of the window in the morning, everyone is shrouded in fog, everyone is wrapped up, and almost no one can be seen within 5 meters; In severe cases, I can't stand the stimulation of foggy days and simply don't go out to work.
