2016年初强寒潮对台湾海峡及其邻近海域影响分析
Analysis of the influence of early 2016 strong cold wave in Taiwan Strait and its adjacent waters
摘要
Abstract
January 21 to 26, 2016, a strong cold wave arrived in Taiwan Strait and its adjacent sea waters. Based on the weather map, the type, origin and development of the strong cold wave happened in Taiwan Strait and its adjacent sea water from 21 to 26 January, 2016, were analyzed. The distribution characteristics of wind and wave during this process were derived from the data of buoys and numerical prediction product. The results are as follows:(1) the strong cold wave is a typical middle cold air invasion process. The longest time of the strong NE wind higher than 6 grades or more continued unabated for 66 hours; The longest time of the disastrous waves when the wave height reached 4 meters or more continued unabated for 45 hours;(2) N-NW wind 8 to 9 levels, rafale 10 levels appeared constantly in Taiwan Strait and its adjacent sea waters. Gale area of the cold wave mainly concentrated in the east coast of the strait and the east side of Taiwan Island, the maximum wind speed reached 21.6 m/s; (3) The low value regions were observed in the central and north of the area when the cold wave arrived. The large wave area liking tongue appeared in the south of the Taiwan Strait. By the NE wind, the wave height in the east coast of the Strait was significantly higher than that in the west. The reason is that the wind and wave direction has sheared when the strong cold wave arrived by the topography of Taiwan Island. When the cold center went down, the wave height in the north decreased obviously, while the wave height in the south increased distinctly.关键词
