Taiwanese meteorologist Wu Derong said today (17th) that on the 18th and 19th, the early morning temperatures in some low-lying areas will still drop to below 10 degrees. In addition, a cold air mass will move southward starting from the 21st, compared to the previous wet and cold wave, the impact will last longer.
Wu Derong, an adjunct associate professor at the Department of Atmospheric Sciences at National Central University in Taiwan, pointed out in a column for the “Meteorological Application Promotion Foundation” that the latest European (ECMWF) model simulation at 8 p.m. on the 17th shows clear and stable weather across the country today; cool in the north and comfortable in the south during the day, with cold mornings and evenings everywhere, so people should pay attention to adjusting their clothing. The temperatures for today are 9 to 21 degrees in the north, 12 to 24 degrees in the central region, 13 to 26 degrees in the south, and 12 to 24 degrees in the east.
Wu Derong mentioned that the latest European model simulation shows that on the 18th and 19th, the eastern side of Taiwan will still be affected by the cold air mass from the continent, with slightly increased moisture content. There will be isolated brief showers on the eastern side of Greater Taipei and the eastern part, while the western part will be mostly sunny with clouds. Northern Taiwan will be cooler, and the central and southern regions will experience cold mornings and evenings, with some low-lying areas still seeing temperatures drop to below 10 degrees; therefore, staying warm is important.
According to Wu Derong, the latest European model simulation indicates that from daytime on the 19th to the 20th, the cold air mass will gradually weaken, and temperatures will rise. Another front will pass through on the 21st, bringing brief showers to Greater Taipei and the eastern part, with the cold air moving southward, causing temperatures to gradually drop. From the 22nd to the 24th, a strong cold air mass will slowly move southward, lasting longer than the previous wet and cold wave; temperatures will drop to the lowest point from the night of the 23rd to the morning of the 24th. However, whether it will meet the criteria for a “strong continental cold air mass” is still uncertain, and further observation is needed.
