Taipei--The Environmental Protection Administration (EPA) issued an air pollution warning on Thursday for southern Taiwan the following day. It forecast that the air quality index (AQI) in the cities and counties of Yunlin, Chiayi, Tainan, Kaohsiung and Pingtung would flash orange, which indicates a level unhealthy for sensitive groups.
High particulate air pollution in areas of southern Taiwan on Friday will be caused by strong winds in the wake of a cold front that arrived on Thursday sending temperatures to new lows nationwide for the winter season, the EPA said.
The AQI in the other areas of the country will remain good to moderate, it added.
The EPA forecast that the AQI in southern Taiwan will remain orange from Feb. 11-12, while the index in central Taiwan will fall to the same level. During that period, air quality in other areas of the country will remain good to moderate, it said.
The EPA has a six-color AQI system; green represents good, with an index reading of 0-50; yellow indicates moderate at 50-100; orange means unhealthy for sensitive groups with a reading of 101-150; red indicates unhealthy with a range of 151-200; purple signifies very unhealthy with a level of 201-300; maroon represents hazardous with an index reading of 301-500.
