入秋以來最明顯的一波東北季風影響台灣,北部及東北部降溫與降雨最為明顯,週三起季風減弱,氣溫將緩慢回升。
受入秋以來最明顯的一波東北季風影響,今(9日)北部及東北部降溫感受最明顯,同時也是水氣最多的一天,大台北、基隆北海岸及宜蘭一帶有短暫陣雨,並須留意局部較大雨勢,今晚明(10日)晨溫度最低,北部至東北部平地低溫約15至18度。
天氣風險公司分析師林孝儒指出,今受入秋以來最明顯東北季風,加上今水氣最多,北台白天高溫僅約20至23度,陰雨天氣影響,體感會比實際氣溫更加濕涼;中南部氣溫也同步下滑,白天雖仍較北部溫暖,但早晚涼意明顯增加。
今晚至明日週二清晨將是這波降溫最明顯的時段,北部至東北部平地低溫約15至18度,局部沿海空曠及近山地區可能再低一些;中南部低溫約18-20度,各地早晚都會明顯感受到涼意。明日白天北部及東北部高溫也僅約20至23度,整日感受偏涼。不過由於環境水氣逐漸減少,降雨範圍也會略為縮小,以桃園以北及東半部仍有局部短暫雨為主,其他地區大致為多雲或晴。
週三(11日)東北季風及冷空氣逐漸減弱,北部及東半部仍有局部短暫雨,其餘地區大致為晴時多雲,白天起各地氣溫開始緩慢回升。到了週四(12日)東北季風進一步減弱,迎風面降雨明顯減少,北部、東北部及東部氣溫回升,各地天氣也逐漸恢復穩定。

The Central Meteorological Observatory issued dual warnings for strong winds and cold waves on the 9th. Xinjiang, Shandong, Jiangsu, Liaoning, Inner Mongolia and other places experienced strong winds, snowfall and severe cooling. The transportation, maritime, heating, and agriculture and animal husbandry departments in various regions responded quickly and took measures such as suspending sailings, clearing snow, and increasing heating parameters to ensure the order of production and life.

The main body of the cold wave moved southward, with local temperatures in eastern Jiangxi, southern Zhejiang, and Fujian falling by 10 to 12°C, and temperatures in 23 provincial capitals and municipalities hit record lows. Beijing, Tianjin, and Lanzhou dropped below 0°C for the first time, and Nanjing, Guiyang, and Kunming fell below 10°C for the first time. It is expected that many places in the central and eastern regions will warm up quickly this week, and the temperature rise in some parts of the Northeast can exceed 15°C. The public needs to pay attention to temperature changes and add or remove clothing in a timely manner.

The cold air from the south brought strong winds to the sea. Hainan issued a yellow wave warning on the 9th. Large to huge waves appeared in many sea areas such as the Qiongzhou Strait. The Sanya Maritime Safety Administration banned some ships from sailing, ticket sales were suspended on the Boundary Islands, and Wanning and other places closed sea-related tourism projects.

Meteorological expert "Taiwan Typhoon Forum | Weather Emergency" pointed out that the northeast monsoon, which has been the strongest since the beginning of autumn, has gradually strengthened, and strong winds have appeared in coastal and open areas. It will turn to rainy weather in Shuangbei, Taoyuan and Yilan, and the temperature will continue to drop. It will gradually become cooler after nightfall in the central and southern parts. People should pay attention to the temperature difference and add clothes in time.

The Yunnan Provincial Meteorological Observatory issued a level IV heavy rain warning at 16:30 on the 8th. It is expected that there will be heavy rains and local heavy rains in many places in the next 24 hours. The Provincial Flood Control and Drought Relief Headquarters launched the fourth-level flood control emergency response at 17:30 that day, launching responses to Baoshan, Chuxiong, Pu'er, Dali, Dehong, Lijiang, Nujiang, Lincang and other places, and required the implementation of the "1262" mechanism and the "Four Unities" requirements, and organized transfers and avoidance in advance.

In the next three days, most of the country will see little precipitation and mostly sunny days, but there will still be frequent rainfall in Yunnan and Guizhou. The cold wave moving south caused the maximum temperature in the middle and lower reaches of the Yangtze River to drop to just over 10°C, and South China became cooler. Guiyang, Kunming and other underground areas fell to single digits for the first time in half a year, and Guangzhou dropped from around 30°C to 24°C.
