If there is a National Day military parade, how can it rain heavily?

First of all, according to the normal situation, it won't snow at the beginning of Beijing 10, because it's not that cold. As for rain, it is possible, but the planned national events will not change the plan. I can also tell you happily that the relevant departments have been paying attention to the climate of the National Day (65438+ 10/0/), and once there are signs of rain, they will use artificial means to drive away the clouds, so that Beijing can achieve rain-free weather that day. This technology has been applied in China on August 8, 2008, the opening day of the Olympic Games, and it is very effective.
