during next year’s Opening and Closing Ceremonies.
Although the duration of the Guangzhou
2010 Asian Games falls into the period considered the “dry season”

Based on research and real-time

The 16th Asian Games are formulating a Plan of Rain Reduction for
the Opening and Closing Ceremonies that will be held at
Guangzhou’s 80,000 seat Olympic Stadium on November 12 and 27,
Catalysis used for artificial rain
elimination includes liquid nitrogen, dry ice and silver iodide.
Dry ice and liquid nitrogen are considered green environmental
protection catalysts which does not harm humans or the
environment. Silver iodide, used in artificial rain dissipation, is
far lower than the national maximum landing standard and should not
have a negative impact on air, humans, water, soil, animals or
As emergency safeguards measure for the
Opening and Closing Ceremonies, scientific rain experiments will
be conducted in a limited time and limited space and are not
expected to have an adverse effect on Guangzhou and the
Measurements of temperature,
wind speed, wind direction, relative humidity, atmosphere pressure
and precipitation will be taken and provided every three hours
during rehearsals for the Opening and Closing Ceremonies.
Forecasts for temperature, wind direction, relative humidity,
atmospheric pressure, precipitation and general sky conditions
will be made three to 36 hours in advance and will be released
On-going meteorological data and
weather reports during the games will be released on all major
communication platforms, including the dedicated Asian Games
information network INFO2010; television; radio; the internet;
telephone hotlines; via fax; displayed on information screens at
Games venues; via e-mail, mobile phone and SMS.
Climate analysis will include inspecting and assessing previous
weather patterns and weather data in the host city and co-host
cities and estimating likely weather including heavy rainfall,
lightning, storms, cold temperatures and fog during the Games.
This will allow appropriate measures to be taken in the event of
unfavorable weather conditions, to minimize disruption to sports,
Games-related events and the Torch Relay.
