Cloudy to Sunny Across Regions; Wu Der-rong: Typhoon Jangmi's Outer Bands to Affect Taiwan on 6/1

Weather expert Wu Der-rong stated today that the front has moved south to the Bashi Channel, and weather across the region is improving to cloudy to sunny. The outer bands of Typhoon Jangmi are expected to affect Taiwan on June 1, bringing localized rain to windward areas. Wu Der-rong, an adjunct associate professor in the Department of Atmospheric Sciences at National Central University, noted in his column "Xie Tianji Classroom" for the Meteorological Application Promotion Foundation that the latest European model (ECMWF) simulations show that the remnants of the front have moved south to the Bashi Channel, and weather across the region is improving to cloudy to sunny. Convection is expected to develop in the mountainous areas of central and southern Taiwan in the afternoon, affecting some flatlands. Wu pointed out that tomorrow will continue to be sunny to cloudy across the region, with a chance of localized rain in the mountainous areas of central and southern Taiwan in the afternoon. Wu said that the latest model simulations show that on June 1, the northeasterly winds from the outer bands of Typhoon Jangmi will bring moisture, turning the weather in the windward areas of the north and northeast into localized rain, with localized short-term rain in the mountains in the afternoon. Northern Taiwan will turn cooler. On June 2, moisture will decrease, temperatures will rise, and the weather will turn cloudy to sunny across the region, with a chance of sporadic rain in the mountains in the afternoon. Wu analyzed that on June 3 and 4, Jangmi will have moved away, and the southwest monsoon will enter the South China Sea, making Taiwan's atmosphere unstable, with afternoon rainfall becoming more pronounced. Wu analyzed that the latest model simulations show that from June 5 to 8, a pattern of the fifth Meiyu front (stationary front) of the season combined with the southwest monsoon is gradually brewing, which is prone to triggering "mesoscale systems," bringing stronger rainfall. The timing will not be limited to the afternoon, and it will gradually enter the peak of the Meiyu season, but as this is a long-term simulation, adjustments in various international models should be continuously observed. Regarding the path of Jangmi, Wu said that Jangmi will strengthen into a moderate typhoon today, moving northwest and then north, passing through the Ryukyu Islands on June 1 and 2, before turning northeast and striking Japan.
