However, many experts have full confidence in Beijing's ability to provide a high-quality weather forecast service during the Olympic Games. "We will never be certain in forecasting the weather, but we can work to reduce uncertainty," said Wang Jianjie, Deputy Director of Beijing Meteorological Bureau.

Another Deputy Director of the bureau, Wang Yingchun said, "Although the unexpected always happens in nature, to accurately forecast the weather is a mission that must be completed." Wang is former Director of the Beijing Institute of Urban Meteorology under the China Meteorological Administration. A project to detail weather forecast technology research for the Olympics directed by her has provided strong scientific and technological support in solving various problems in Olympic weather forecasting.

The premise of detailed weather forecasts is meteorological observation. Meteorological departments have already set up automatic weather stations in many Olympic venues since 2003. In addition to observing the temperature, pressure, humidity, wind direction and wind speed, the stations also observe atmospheric data that are specifically important to sporting events. Up to now, Beijing has set up almost 200 meteorological observation stations, which are evenly distributed in urban areas at one for every 5 km, and in suburban areas at one for every 10 to 15 km.

Apart from the host city, the Beijing Olympic Weather Service Center has set up meteorological observation stations in co-host cities and important areas for the torch relay, forming a video service system that links many places.

The Beijing Meteorological Bureau has also provided an assurance that meteorological support for the Olympic Games is now well prepared, and a detailed weather forecast system for the Olympics has been established.

Deputy Director Wang Jianjie indicated that in light of the different characteristics of various sporting activities, the relative departments could provide climate analysis, live service technology, emergency support and other comprehensive forecasting services. "Apart from the conventional observation, the transmission time of the observation data of the automatic meteorological stations surrounding the Olympic venues has been shortened from day-to-day to hour-to-hour and even every 10 minutes," he said.

"Before May this year, Beijing will set up information kiosks, display screens and warning towers in some streets and blocks. Meteorological departments will display information on a screen, providing citizens and tourists with scientific, useful and easy-to-understand meteorological information that is up-to-the-minute," said Wang Jianjie.
