Firecrackers during the Chinese New Year may have affected the
weather but were not the cause of Wednesday's thick fog in Beijing,
said Director of the Beijing Meteorological Observatory Guo Hu on
Thursday.
Guo made the remarks in response to local media reports which
pointed the blame for Wednesday's fog that canceled flights and
closed down highways at exploding firecrackers.
"We had actually forecast a haze in Beijing for Wednesday,
although it developed into a fog due to an increase in humidity
after being affected by fog from Shandong Province and vapor from
the Bohai Sea," Guo said.
It had been windless in Beijing since Tuesday and particles in
the air had been accumulating, resulting in Wednesday's thick fog,
explained weather forecasters with the Beijing Meteorological
Observatory.
The Capital International Airport was forced to cancel 190
flights, while sections of seven Beijing and 10 Tianjin highways
were also forced to close temporarily.
It finally became clear on Thursday after the fog dissipated
with strong winds.
Fireworks are part of traditional celebrations marking Spring
Festival, the most important holiday for Chinese, which fell on
Feb. 18 this year.
Since Beijing lifted a 12-year ban for last year's Spring
Festival, fireworks have made a loud return to the Chinese capital.
The sales of fireworks by two major suppliers have reached 380,000
boxes in Beijing this year, compared with 240,000 boxes last year,
according to a municipal public security official.
