Fewer poor air quality days recorded this year

From January to October this year, Taipa air quality monitoring station recorded seven days with poor air quality, 26 days fewer compared to the same period last year, according to Chang Sau Wa, Director of the Macau Meteorological and Geophysical Bureau’s (SMG) monitoring center.
The decrease represents a 73% drop year-on-year. In Chang’s opinion, the drop shows that air quality is closely related to human activity.
In addition, Chang revealed that the bureau will tighten standards for pollutants such as PM10, PM2.5 and sulfur dioxide in accordance with the World Health Organization guidelines.
As a result, it expects that the number of days with poor air quality in the future will increase. However, the potential increase in the number of poor air quality days may only be due to the higher standards.
In addition to air quality, Leong Weng Kun, Director of SMG, also responded to the concerns related to typhoon signal issues. According to Leong, the bureau mainly depends on numerical forecast data. If the bureau only uses empirical analysis, the error in typhoon forecast will be greater.
Leong pointed out that every time a typhoon signal is issued, there is an internal consultation system. According to Leong, SMG will fully discuss the scientific data and the impact on the public.
Macau will also communicate closely with the meteorological departments of Guangdong and Hong Kong, and will soon exchange information with these regions. However, specific judgments and decisions are made in accordance with Macau’s own circumstances. JZ
