Northeast monsoon to weaken Monday before another cold front arrives Wednesday

Northeast monsoon to weaken Monday before another cold front arrives Wednesday

2024-01-07

The mercury dropped again on Sunday with the arrival of a cold air mass. Along with the cold air, pollutants from the mainland were also carried into Taiwan by the northeast monsoon. The outlying counties of Kinmen and Lienchiang got a code red air quality alert, and the entire western half of Taiwan got a code orange. For the coming week, another cold air mass is expected to make itself felt on Wednesday with lows of 13 degrees. As for election day on Saturday, the weather is looking to be sunny and mild.

The sky over Taipei looked smoggy early Sunday morning. Even Taipei 101 was enveloped in a haze. Scooter riders and pedestrians all had their masks on. The poor air quality is the result of air pollution from the Chinese mainland being carried into Taiwan by the northeast monsoon.

If you look at this area that I’m pointing at, you can see patches of gray. These are the air pollutants that were brought in by the northeast monsoon.

According to the environment ministry’s air monitoring data, Kinmen and Lienchiang counties got a code red air quality alert on Sunday, meaning residents should avoid outdoor activities. The entire western half of the island also got a code orange. Sensitive groups were advised to pay special attention to the air quality, which is expected to improve starting Monday. Looking ahead, there will be two waves of cold air affecting Taiwan in the coming week.

The real drop in temperature will come on Wednesday, when a cold air mass begins to affect Taiwan. We can see that the lowest temperatures will occur in the early morning of Thursday and Friday. In the north and northeast, the temperature will likely be around 12 or 13 degrees.

This wave of the northeast monsoon will taper off on Monday, raising the mercury. However, on Tuesday, a cloud system in South China will move eastward, leading to brief periods of rain in the north and in the eastern half of the island, as well as the central mountainous regions. On Wednesday, a cold air mass from the mainland will arrive, with lows dropping down to around 13 degrees. There will be relatively little rainfall, and it will remain cold and dry until Friday. On election day Saturday, the cold air mass will weaken and temperatures will begin to rise.

On election day, there will be less moisture with highs reaching 20 to 22 degrees.

The Central Weather Administration also published a photo that was taken early Sunday morning on Taiwan’s highest peak, Yushan. It shows a spectacular sky with clouds forming in a golden arch. Former head of the CWB Cheng Ming-tien explained on social media that the formation was the result of altocumulus clouds coming into contact with airflows moving in a different direction. The sunlight hit at just the right angle, creating the rare natural phenomenon.

東北季風明減弱溫度回升 週三變天轉乾冷 低溫探13度

2024-01-07

天氣明顯變冷,冷氣團南下,中國空氣污染物,也跟著東北季風一起吹進台灣,不只離島空氣品質警示達到紅色,整個西半部也亮起橘燈,未來一週還會有冷空氣影響台灣,下周三四最冷,溫度來到13度左右,不過,投票日當天會是晴朗穩定的好天氣。

一大早放眼望去,台北的天空灰濛濛,就連101也有點看不清楚,路上的機車騎士、行人口罩戴緊緊,因為中國空污隨著東北季風,吹進台灣,空氣品質越來越差。

“在我所指部分,其實可以看到是有一點點灰灰的顏色,這部分其實就是,東北風夾帶下來的空污”

根據環保署監測,週日金門和連江地區,已達紅色警示,要盡量減少戶外活動,整個西半部,也都亮起橘色警示,敏感族群要特別注意,髒兮兮的空氣,等到周一後就會改善,未來一周,會有兩波冷空氣影響台灣。

“真正的降幅要到了10號(周三),當冷氣團開始影響台灣,我們可以看到在最低溫的時候,會是在11號(周四)及12號(周五)的清晨。北部及東北部,有可能都會在12到13度左右”

這波東北季風,下周一就會減弱,氣溫回升,不過緊接著,周二華南雲雨區東移,北部、東半部及中部山區局部有短暫雨,周三大陸冷氣團來襲,溫度最低掉到13度左右,降雨情形會減少,預計乾冷到周五。周六投票日,冷氣團減弱,氣溫回升、天氣變好。

[[氣象署預報員 陳姵安]]
“選舉日那一天,其實水氣也是比較偏少一點的,各地的高溫都會是在20到22度左右”

氣象署也分享,周日清晨在玉山的美景,天空中出現半弧形雲,閃著金黃色光芒。前氣象局長鄭明典解釋,右側是高積雲,邊緣有不同性質氣流接觸,形成弧形的界面,在陽光下多了色澤變化,是難得的天然美景。
