A cold air mass from the mainland is moving southward, bringing chilly weather to Taiwan today (14th). The Central Weather Bureau reported that frost and fog were observed at Yushan Weather Station at 8 a.m.
The Central Weather Bureau of Taiwan posted in a news media group, stating that Yushan Weather Station reported overcast skies with fog at 8 a.m., visibility was poor due to the clouds and mist, with a temperature of minus 1.6 degrees Celsius, west-northwest winds averaging at 5 on the Beaufort scale, gusting up to 7, and experiencing frost and fog.
Associate Professor Wu Derong of the Department of Atmospheric Sciences at National Central University in Taiwan mentioned in a weather forecast show that the weather in Taiwan will be cold today and on the 15th, with two cold air masses, one weak and one strong, expected next week.
Wu Derong stated that according to the latest European Center for Medium-Range Weather Forecasts (ECMWF) model simulation from the evening of the 13th, there might be brief showers in the north and east on today and tomorrow, with slightly more clouds in the north on the 15th and 16th, mostly sunny to partly cloudy in the central and southern regions, and a chance of brief showers in the east. Northern Taiwan will be colder today and on the 15th, with comfortable daytime temperatures in the central and southern parts and colder mornings and evenings. Tonight to early morning on the 16th, some low-lying areas could see temperatures drop below 10 degrees, so staying warm is crucial.
Wu Derong pointed out that various international models indicate that the cold air will gradually weaken on the 16th and 17th, with temperatures slowly rising, but northern Taiwan will still be cool. The western regions will be partly cloudy to mostly sunny, with a chance of brief showers in the east. Another weak cold air mass will move south on the 18th, combining with the already weakening cold air, resulting in cooler weather mostly in northern Taiwan from the 18th to the 20th.
Wu Derong mentioned that a stronger cold air mass is expected to move southward on the 21st and 22nd, but the exact timing of its arrival and whether it will cause record low temperatures remain uncertain! Since these are late-stage simulations, there are significant differences among international models, which are continually being adjusted, so further observation is necessary.
