It is reported that Shanghai Tower is located at No. 501, Yincheng Middle Road, Lujiazui Financial District, Shanghai, is a giant high-rise landmark skyscraper in Shanghai, is now the tallest building in China, the third tallest building in the world, was built on November 29, 2008, and completed the overall construction work on March 12, 2016.
Shanghai Tower is mainly used for office, hotel, commercial, sightseeing and other public facilities, the main building is 127 floors above ground, and the building height is 632 meters. It is understood that the snow cover is an open-air area of the building and is not open to the public.
Why does the top layer freeze?
Meteorologists say that whether or not snow is produced on the top of high-rise buildings such as the Shanghai Tower is related to the vertical distribution of temperatures. With a height of 632 meters, the temperature at high places can easily drop below 0, and it is normal for snowfall or even snow accumulation. However, the snowflakes gradually melt as they fall, and when they reach the point where people are visible on the ground, they turn into rain or sleet. That's why "it's hard to snow in Shanghai, but it's not hard to snow in Shanghai Tower".
The operation of Shanghai Tower said that because of this, "Shanghai Tower" has always attached great importance to the prevention of cold waves, especially the impact of cold wave weather on key parts and important facilities. In the event of a cold wave, the operator will strengthen the 24-hour on-duty work, strengthen the engineering and safety departments, closely track the impact of the cold wave, keep abreast of the operation and service guarantee, and ensure smooth communication. Implement temperature monitoring, do a good job in cold protection and warmth protection for front-line staff, focus on cold and freeze protection of facilities and equipment such as drainage, HVAC and fire protection, pay attention to the relevant ice and snow conditions of buildings, carry out de-icing and snow removal operations in a timely manner, and set up safety warnings. The customer service staff issued cold wave weather tips to the merchants and tenants in the building in a timely manner, reminding the tenants to strengthen protection and ensure the orderly operation of the building.
In the past few days, the temperature in Shanghai has been low and the humidity is high, and the average temperature in the rooftop area of Shanghai Tower is about minus 5 degrees, and natural phenomena such as ice and snow have appeared in some areas. As the temperature rises, the frozen areas on the roof gradually melt, and ice and snow fall in some areas.
It is understood that from February 25, Shanghai Tower will temporarily control the unsheltered areas and road sections of Gate 2 of the building.
