(Central News Agency reporter Yu Xiaohan, Taipei, 27th) Meteorological expert Wu Derong said today that the lingering front will continue to linger near Taiwan today and tomorrow. There will be local showers or thunderstorms in various places, and the atmosphere will be unstable. Pay attention to the possibility of severe weather, and it will not rain until tomorrow night. will stop.
Wu Derong, an adjunct associate professor of the Department of Atmospheric Science of National Central University, said today on “Sanli Quasi-Meteorology. Big Brother’s Secret” that the lingering front will continue to linger near Taiwan today and tomorrow. There will be localized showers or thunderstorms in various places, and the atmosphere is unstable. We should be careful to guard against “convective systems” “, accompanied by “lightning strikes, strong winds, instant heavy rains”, etc., small-scale “violent weather” causes disasters. When its energy is exhausted or leaves, there will be gaps, and the rain will stop tomorrow night.
Wu Derong pointed out that the stagnant front will move northward from the morning of the 29th to the 30th, with a long gap; it will be cloudy at times, the temperature will rise, and there is a chance of local short-lived showers near mountainous areas in the afternoon.
Wu Derong said that the front will approach from the afternoon of the 30th, and the lingering front will linger near Taiwan on May 1 and 2. It is another wave of unstable weather that is prone to the development of “medium- and small-scale convective systems” and should continue to be observed. On May 3 and 4, the stagnant front will move away, the weather will improve, and there is a chance of local brief showers near the mountainous areas in the afternoon.
Wu Derong pointed out that generally speaking, the medium-term model or the AI (artificial intelligence) model is theoretically unable to accurately simulate the spatial and temporal changes of the “convective system”, so that the daily rainfall it simulates (is the accumulated rainfall of waves of convective systems) ), often have large errors and are not suitable for direct reference. Instead, “short-term model” simulation must be used, combined with the “real-time forecast” process, to make up for the shortcomings of technology by updating forecasts in a timely manner.
