Arizona Tribune - Snow falls on Chinese capital as two-week Olympics countdown starts

Temperatures fell below minus nine degrees Celsius (15 degrees Fahrenheit) as commuters struggled to work Thursday morning, with snow dusting roads, buildings, and Olympics venues across the megacity of nearly 22 million.

Although temperatures in Beijing regularly drop well below freezing in the winter months, the city is very dry which makes snowfall unusual.

The Beijing Games, which start on February 4, will depend almost entirely on artificial snow.

The venues use automated snow-making systems that monitor air temperature and humidity to maximise production.

Organisers at the Winter Olympics say the snow makers are powered by renewable energy and will not damage mountain ecosystems, while the water they use will return to local reservoirs as the snow melts in spring.

But experts say the reliance on man-made snow undermines Beijing's pledge to hold a "green" Games.

In January last year, temperatures in the Chinese capital plunged to their lowest level for more than five decades -- but without any snow and little ice.

The mercury dropped to -19.6C -- the lowest since 1966, when temperatures in the city fell to -27.4C.

Ahead of the Beijing Games, the government has been keen to promote winter sports, with huge construction of snow resorts leading to millions of fresh devotees.
