Beijing has begun to provide weather forecasts tailored for
heating in cold weather in a move to reduce energy consumption and
pollution in the city.
The Beijing Meteorological Bureau initiated the service on
Tuesday ahead of the heating season, which usually runs from
November 15 till next March in Beijing.
Cities in northern China, as in Beijing, normally provide public
heating services for residents when the winter comes, with
facilities, including big boilers, connected to each household with
supplies of hot water circulating in the pipes.
The public heating system in Beijing aims to keep indoor
temperatures above 16 degrees Celsius, but some people complain the
temperature is too high when it gets warmer as the daily heating
temperature is fixed all through the heating season.
A new system with more than 100 monitoring spots across the city
has been set up to make it possible to tune heating systems with
appropriate figures, said Ding Deping, head of the specific
forecast department of the municipal bureau.
It would provide indoor and outdoor temperatures of residential
areas and wind speeds, along with data such as water temperatures
into and out of boilers, for the bureau to analyze and make
forecasts, said Ding.
Ding said heating service providers and individual households
could tune the heating temperatures based on forecasts of the
boiler's water temperatures a few days ahead of time.
The monitoring system covers major residential areas of the
city, including outer suburbs.
The bureau has been providing trial services for dozens of
heating units in Beijing since the winter of 2003, Ding said.
The new service could slash energy consumption for heating in
Beijing by five percent each year, which amounted to about 100
million yuan annually on estimates of Beijing's yearly spending of
two billion yuan (US$267.7 million) on heating, said Ding.
He said services, including the heating index and temperature
forecasts within one to three days, would be immediately available
for staff at the Beijing District Heating Group, which provided
heating for one third of the city, and enterprises and communities
that provide regional services.
Individuals could tune their own heaters at home according to a
heating index published in the media, which would range from the
minimum level to the highest fifth grade based on factors such as
the temperature, sunlight, wind speeds and humidity.
Some Beijing residents in new residential areas are not provided
with public heating system, but with household heaters, and they
can easily tune the heating temperatures freely at home.
The reduced energy consumption would also mean a "bluer" sky for
Beijing during the winter, as many city boilers are coal fired,
which causes heavy pollution with sulfur dioxide emissions.
Beijing has been replacing coal-fired boilers to lessen
pollution and aims to have more than 40 percent of the area
provided with natural gas by the end of this year, and 50 percent
by 2010.
The capital has come up with a series of campaigns to improve
the air quality since the beginning of this year for the 2008
Olympic Games.
From August 17 to 20, about 1.3 million cars were banned from
the city roads each day to test the effect on air quality for the
Olympic Games.
The municipal government cut metro ticket prices by more than 30
percent, and offered discounts up to 60 percent on bus tickets
earlier this year, to encourage public transport use.
Beijing Shougang Group, China's leading steel manufacturer, has
pledged an output reduction of more than 70 percent from July to
September next year to ensure the Olympics can enjoy better air
quality.
The municipal meteorological bureau has also beefed up its
efforts this year to ensure more accurate weather forecasts during
the Olympic Games.
China has successfully launched its second professional
geostationary orbit meteorological satellite, Fengyun-2D (FY-2D),
on December 8 last year to provide better weather forecast services
for the Games.
