| 摘 要： | 由于地理特征独特,北部湾地区常年遭受热带气旋的影响。热带气旋引起的波浪灾害和风暴潮灾害对广西沿海经济、生活造成了巨大影响。本文采用中国气象局热带气旋最佳路径数据集,研究了1980—2015年间进入北部湾的热带气旋的变化及特征,对北部湾海域内热带气旋的频数、强度、持续时长、功耗指数等年际趋势变化进行分析。结果表明:1980—2015年,北部湾地区热带气旋的频数、持续时长呈波动减小趋势,其强度呈波动增加趋势,整体上功率耗散系数(Power Dissipation Index,PDI)的正效应大于负效应。本研究为北部湾地区的海洋防灾减灾提供了相关科学依据。

| Abstract: | Due to the unique geographical characteristics, Beibu Gulf area has been affected by tropical cyclones all year round. Wave disasters and storm surge disasters caused by tropical cyclones have a great impact on the economy and life in Guangxi coastal areas. In this paper, adopting the best tropical cyclone track dataset from China Meteorological Administration, the changes and characteristics of tropical cyclones entering the Beibu Gulf between 1980 and 2015, including the inter-annual trends of the frequency, intensity, duration and power consumption index of tropical cyclones in the study area were analyzed. The results show that from 1980 to 2015, the frequency and duration of tropical cyclones in Beibu Gulf area showed a trend of decreasing fluctuations, and their intensity showed an increasing trend of fluctuations. The positive effect of the power dissipation index (PDI) was greater than the negative effect on the whole. This study provides a relevant scientific basis for the prevention and reduction of marine disaster in Beibu Gulf area. |
