Meteorological expert Wu Derong: There will be rain in the eastern half of the north. It will get cooler in northern Taiwan next Monday or Tuesday, and there is a high chance that Typhoon Caiyun will not invade Taiwan.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science of National Central University, pointed out that it will turn rainy in the northern and eastern half of Taiwan from tomorrow to next Sunday (2nd to 4th); on Monday and Tuesday (5th and 6th), northern Taiwan will become cooler and the temperature will drop significantly; the No. 26 light typhoon colorful cloud will form in the early morning of today (1st) and is not expected to invade Taiwan.

Wu Derong said in the Meteorological Application Promotion Foundation's "Tianji Classroom" column today that the latest (ECMWF) model simulation (at 20:00 on September 30) shows that today it will be sunny and cloudy in various places, with occasional local short-term rainfall in the afternoon in mountainous areas. It will still be hot in the daytime and cool in the morning and evening in various places. The highest temperature in the central and southern parts is still around 36 degrees. You should be careful about ultraviolet rays around noon, which can reach excessive and dangerous levels.

Wu Derong pointed out that the latest model simulation shows that moisture will increase from tomorrow to next Sunday, with local brief rains in the northern and eastern half, and local short-lived rains in the mountainous areas in the afternoon. There will be heavy rains in the northern mountainous areas and the northeast; the temperature will drop slightly, and the central and southern parts will still be hot during the day, and various places will be slightly cooler in the morning and evening.

Wu Derong said that the latest model simulation shows that the northeast monsoon will strengthen next Monday and Tuesday, the temperature will drop significantly, and northern Taiwan will become cooler; there will be rain on the windward side next Monday, and the moisture will gradually decrease next Tuesday, and the rainfall on the windward side will gradually decrease.

Next Wednesday (7th), the weather will improve in various places, with low temperatures in the early morning and large temperature differences between day and night; there will be occasional local brief rainfall in the afternoon and the eastern half of the mountainous area.

Wu Derong analyzed that the latest (2 o'clock on the 1st) Meteorological Administration's "path potential forecast map" shows that the No. 26 light station Caiyun is over the sea northeast of Guam. It will generally turn northward in the future, heading towards the sea southeast of Japan. Its intensity will increase and its scope will continue to expand.

Wu Derong said that the latest European model series simulation shows that Caiyun will develop into a large typhoon. The simulated path is generally northerly with the highest probability, and there is no chance of invading Taiwan. However, the model will continue to adjust and is uncertain, so we should continue to observe it.
