Olympic Games

Saturday, February 9, 2008

This is our first news, and to tell you the truth, is the strangest one! Take a look:

The Beijing Meteorological Bureau, instructed to ensure the roofless Bird's Nest stadium stays dry on the opening of the Olympic Games, say that experiments to prevent light precipitation from occurring have worked using two methods.
Clouds below freezing were sprayed with a liquid nitrogen-based coolant that breaks droplets up into smaller sizes; those above freezing received silver iodide to produce a cloud-suppressing downdraft by speeding the process of droplet coalescence.
The opposite effect may be attempted to force rain to fall before it gets to the Olympics. A pre-Games highlight involving the torch being taken to Mount Everest's top is also being prepared by the bureau, promising "very detailed" wind reports.
