Cold air mass to send temperatures down starting Thursday

Taipei--The arrival of a cold air mass from China and a weather front is expected to push temperatures lower around Taiwan from Feb. 23 to 27 and bring rainfall, the Central Weather Bureau (CWB) said Tuesday.

Temperatures on Feb. 23 could hit lows of 13 degrees Celsius in northern Taiwan, 16 degrees in central Taiwan, 18 degrees in southern Taiwan and 19 degrees in eastern Taiwan, according to CWB data.

All parts of the island are expected to see showers, thunderstorms or sporadic rain that day, the bureau said.

From Feb. 24 to 27, the mercury could fall further to 11 degrees in the north, 14 degrees in central Taiwan, 15 degrees in the south and 16 degrees in the east as the cold air mass strengthens, according to the bureau.

Northern and northeastern Taiwan could see rain, while central, eastern, southeastern Taiwan could see brief showers during that period, the bureau said.

Before the colder weather arrives, rain is likely in northern, eastern and southern Taiwan on the evening of Feb. 21 and into Feb. 22 as the weather front approaches.

Meanwhile, the air quality on Tuesday was generally average along much of Taiwan's west coast, but there were pockets of poorer air quality in the south, according to the Environmental Protection Administration.

As of noon Tuesday, the air quality index was at an "unhealthy," or red, level in the Kaohsiung metropolitan area, where there were particularly high concentrations of PM10 particulates.

The index flashed orange, indicating air quality "unhealthy for sensitive groups," in Tainan and Chiayi City in southern Taiwan and parts of Yunlin and Nantou counties in central Taiwan.

The only parts of the country in which the index flashed green, signaling "good" air quality, were Yilan and Hualien counties in eastern Taiwan and parts of New Taipei in the north.

The EPA's air quality index takes into account ozone, PM2.5 and PM10 particulates, carbon monoxide, sulfur dioxide and nitric oxide concentrations in the air.
