Lin De'en, a doctor of atmospheric sciences at National Taiwan University, said that the northeast monsoon will strengthen from the 9th of this month and is expected to affect Taiwan from the 10th to the 11th. It will gradually weaken on the 12th and the impact will last for about 3 to 4 days. There will be local short-term rain on the windward side, and the low temperature in the morning and evening is expected to be about 22 to 24 degrees. When it encounters overcast and rainy weather, the body will feel significantly cooler.

Lin Deen posted on Facebook on the 7th that according to the latest meteorological information from the Central Meteorological Administration this morning, from a meteorological point of view, the northeast monsoon moved southward on the 9th. The most significant reaction was not the temperature field, but the low-level wind field near 850 hectopascals (hPa) began to transform into a larger and stable northeasterly wind environment. Lin Deen also explained 4 main features.

Lin Deen pointed out that first of all, the northeast monsoon will strengthen from the 9th, affect Taiwan from the 10th to the 11th, and gradually weaken on the 12th. The overall impact time will be about 3 to 4 days, of which the largest temperature drop will occur in the morning and evening of the 10th.

Secondly, in terms of rainfall, affected by the northeast monsoon, the north, northeast and east of the windward side will become humid, with increased cloud cover and local brief rains. The central and southern parts are located on the leeward side of the northeast monsoon, and the weather will remain cloudy to sunny, relatively stable, and the impact will not be significant, but there will still be local brief showers in the afternoon.

Third, in terms of temperature, Lin Deen pointed out that since the intensity of this wave of cold air is not strong, the morning and evening low temperatures in the north and northeast are expected to be about 22 to 24 degrees, slightly lower than the previous period by about 1 to 2 degrees. Especially when it is rainy, the body will feel significantly cooler.

Fourth, when the northeast monsoon travels southward and encounters the windward slopes of the Snow Mountains and the Central Mountains, it will cause terrain uplift. Therefore, places such as Keelung, Yilan, and the North Coast are particularly prone to low clouds and moisture accumulation, resulting in localized short-lived rains, which may also last longer. These areas are usually the areas where the feeling of dampness and coolness is most obvious.
