MeteoWorld Pavilion

Expo visitors need not worry about Shanghai's constantly changing weather during the Shanghai World Expo. They will receive precise updated weather forecasts free on their mobile phones.

Construction began today on the pavilion of the United Nations' World Meteorological Organization in Pudong. The organization will build a hi-tech weather station inside the pavilion.

The station will update weather forecasts for all visitors every one to three hours. During the city's plum rain or typhoon seasons, the station will issue weather alerts and send updates every half an hour, said Xu Xiaofeng, deputy director of China Meteorological Administration and commissioner general of the organization's Expo exhibition.

People will also be able to get weather updates from a large screen in front of the pavilion or on the pavilion's Expo Website.
