The Shenzhen meteorological bureau would keep a close watch on the weather during the Universiade in August when there was rain or thunderstorms on an average of every two days.

The bureau also planned to use artificial means to induce rain before it reached the venues of the opening and closing ceremonies.

However, a meteorologist said it would take at least 24 hours for cloud seeding to have an impact in designated areas.

There was also the possibility of a typhoon and torrential rain and high temperatures, according to bureau records, yesterday’s Southern Metropolis Daily reported.
