Taipei: Temperatures across Taiwan were lower than usual early Monday due to a continental cold air mass and radiative cooling but were expected to rise during the day as the weather system weakened, the Central Weather Administration (CWA) said.
According to Focus Taiwan, the CWA issued a cold surge advisory early Monday for parts of New Taipei and Hsinchu, Miaoli, and Yilan counties. The advisory was in effect for most of the morning, indicating that temperatures could fall below 10 degrees Celsius. The lowest temperatures recorded in low-lying areas around Taiwan early Monday were 7 degrees in Guanxi Township in Hsinchu County and 8.5 degrees at stations in Gongguan and Touwu townships in Miaoli County, the CWA data showed.
On Tuesday, radiative cooling will again affect the weather, leading to slightly cooler temperatures early in the morning and at night, with western Taiwan experiencing particularly large day-night temperature differences, the CWA forecasted. Daytime highs on Tuesday are expected to be 23-26 degrees in northern Taiwan, 24-26 degrees in central Taiwan, and 26-28 degrees in the south. The forecast for both Monday and Tuesday predicts partly cloudy to sunny skies across most parts of Taiwan, with only isolated showers anticipated along the northern coast, in northeastern and southeastern Taiwan, and in the Hengchun Peninsula.
Meanwhile, independent meteorologist Wu Der-rong noted that a “cloud street” was forming over the sea as cold air moved across relatively warm ocean surfaces. However, no rainfall had materialized from it as of Monday morning. The latest European forecast model indicated that weather conditions around Taiwan will remain clear and stable through Tuesday morning, with comfortable daytime temperatures when the sun is out but very cold conditions at night and in the early morning.
Due to enhanced radiative cooling, some low-lying areas in central and northern Taiwan could again see temperatures drop below 10 degrees overnight and early Tuesday, Wu explained. From Tuesday through Thursday, daytime conditions are forecast to be warmer, with cool mornings and evenings and significant day-night temperature differences, Wu added.
