Taipei, Nov. 29 (CNA) Daytime temperatures in northern Taiwan are expected to reach 28 degrees Celsius on Wednesday as seasonal northeasterly winds weaken, the Central Weather Administration (CWA) has forecast.

The CWA said temperature highs in the north are expected to rise two to three degrees from a day earlier to 27-28 degrees Wednesday before falling to about 20 degrees at night.

In the south, which has been less affected by the latest round of northeasterly winds, daytime temperatures are expected to hover around 28 degrees, with highs in Pingtung County likely to hit 30 degrees, the CWA said.

Due to radiation cooling effects -- the cooling of the ground under clear skies, light winds and dry conditions -- temperatures at night in southern Taiwan will likely fall to 21-23 degrees, the CWA said.

The agency forecast cloudy to sunny skies for most of Taiwan on Wednesday with only sporadic showers in mountainous areas in the north and the east as well as in the outlying Kinmen County, the CWB said.

Another round of northeasterly winds are expected to set in Thursday and continue into Sunday, sending highs in northern Taiwan plunging to around 22 degrees during that time, the CWA said.

The CWA said there will be more moisture in the air from Thursday to Friday before slowly drying up Saturday and Sunday.

Meanwhile, the weakening seasonal wind system will make it harder to disperse pollutants in the air in western Taiwan on Wednesday, with ozone density likely to rise, the Environmental Protection Administration (EPA) said.

According to the EPA, the air quality is expected to be "good" to "fair" in most of northern Taiwan, and the Matsu and Penghu islands on Wednesday.

However, the air quality index is expected to flash an "orange" warning in much of western Taiwan from Hsinchu and Miaoli counties all the way to Kinmen County, signaling unhealthy levels for sensitive groups, the EPA said.
