The bird's nest has no roof. What if it rains?

When the Bird's Nest holds a grand event, the state will analyze the weather near the Bird's Nest and carry out artificial rain suppression if necessary.

The stadium can hold 90,000 seats, and it was originally intended to install an exquisite openable roof. This roof is also one of the reasons why the stadium presents the shape of a reinforced concrete basket, hence the name "Bird's Nest". But later, the relevant departments canceled the roof design, thus saving 10% of the project cost and 15000 tons of steel. However, even if the roof was cancelled, the stadium still consumed 45,000 tons of steel.

But it doesn't matter, the planners in Beijing have a new idea: if there is no roof, stop the rain.

For many years, meteorologists in China have been experimenting with weather modification, shooting chemical shells at the clouds for artificial rainfall, or obviously stopping the rainfall.

Unfortunately, the audience may feel sorry because officials say their skills are limited. According to media reports, Chen Zhenlin, deputy director of the Department of Prediction and Disaster Reduction of China Meteorological Bureau, said that weather modification can only affect some small-scale or weak precipitation clouds; If there is heavy rainfall, there is nothing we can do.
