The temperature difference between day and night is huge and the autumn tiger will arrive tomorrow. Typhoon Qiangbi will form and may become a strong typhoon.

Meteorological experts pointed out that due to the influence of radiation cooling this morning, the low temperature in Hsinchu and Kansai dropped to 16.5 degrees. Today, the temperature difference between day and night continues to be large in various places. The west will be sunny and stable during the day, and there will be some short-lived rain on the windward sides of the north and east. The moisture will gradually decrease on the east side from tomorrow to next Tuesday, and the weather will turn into an "autumn tiger" type. (File photo)

Meteorological experts pointed out that due to the influence of radiation cooling this morning, the low temperature in Hsinchu and Kansai dropped to 16.5 degrees. Today, the temperature difference between day and night continues to be large in various places. The west is sunny and stable during the day, and there are local brief rains on the windward sides of the north and east. From tomorrow to next Tuesday, the moisture on the east side will gradually decrease, and the weather will turn into an "autumn tiger" type. However, the northeast monsoon will strengthen next Wednesday, and rain will turn on the windward side. Experts also mentioned that the tropical depression east of Guam will develop into a light typhoon "Qiangpi" today, and there is a chance that it will continue to strengthen into a "strong typhoon" in the future.

Wu Derong, adjunct associate professor of the Department of Atmosphere at National Central University, wrote in a column for the "Meteorological Application Promotion Foundation" today that due to the effect of radiation cooling, the top three lowest temperatures on the ground this morning were in Guanxi, Hsinchu, 16.5 degrees, Shoufeng, Hualien, 17.5 degrees, and Donghe, Taitung, 17.6 degrees; the lowest temperatures on the ground in each area were about 18 to 21 degrees.

Wu Derong said that today there will be slightly more water vapor on the sea surface on the east side. There is a chance of local short-term rain on the east side and the eastern half of Taipei. The western half will be clear and stable, and there will be occasional local short-lived rainfall in the afternoon in the mountainous areas. During the day, it is slightly hot in the north, hotter in the south, and cooler in the morning and evening. The temperatures in each region are as follows: 20 to 30 degrees in the north, 20 to 34 degrees in the center, 21 to 35 degrees in the south, and 18 to 34 degrees in the east.

Wu Derong explained that the moisture on the east side will gradually decrease from tomorrow to next Tuesday, and the eastern half will be cloudy and sometimes sunny, with the chance of occasional short-term rainfall; the western half will be clear and stable; the daytime temperature will be high, and the temperature difference between day and night will be large, which is an "autumn tiger" pattern. The northeast monsoon will strengthen next Wednesday, with rain on the windward side and a drop in temperature; the impact on the leeward side will be slight.

Wu Derong mentioned that according to the latest forecast from the Meteorological Administration, the tropical depression east of Guam will develop into a light platform "Qiangbi" today, heading northwest and west toward the sea south of Japan, and there is a chance that it will continue to strengthen into a "strong platform" in the future. According to the latest European model simulations, the tropical depression in the sea east of Guam will develop into a station. Its future movements will mostly be in the sea south of Japan and turn northeastward. The simulated paths of each system are very scattered, showing "large uncertainty" and need to be further observed.
