中文摘要: 热带气旋是全球最具破坏性的天气系统之一。随着全球气候变暖,热带气旋的异常活动受到了各国政府、民众和学术界广泛的关注。本文分析了热带气旋对海洋沉积物"从源到汇"过程中的作用及其机制,表明热带气旋是陆源沉积物、有机碳和污染物通过河流向海洋输送的重要控制因素;热带气旋产生的波浪、强流和内波可造成河口和陆架沉积物再悬浮、侵蚀、液化甚至剪切破坏,对陆架沉积物向深海输送起重要作用。虽然热带气旋有随全球变暖而增强的趋势,但热带气旋发生频率与全球变暖之间的关系尚不明确,对未来热带气旋发生频率的预测结果也存在较大分歧,对该问题的研究需要长期、高分辨率的热带气旋记录,使用热带气旋沉积记录研究热带气旋活动规律具有必要性和可行性。
英文摘要: The tropical cyclone is one of the most devastating weather systems in the world. With the global warming and climate change, the abnormal activities of tropical cyclones are widely concerned by the governments, the academic researchers and the public. This paper analyze the role and mechanism of tropical cyclones in the process of source-to-sink on marine sediments, and our research result shows that tropical cyclones play an important role in transporting terrigenous sediments, organic carbon and contaminants to the oceans. Tropical cyclone induced waves, strong currents and internal waves can cause the resuspension, erosion, liquefaction and even shear failure of sediments in estuaries and continental shelves, which greatly facilitates the transportation of sediments to deep oceans. Although tropical cyclones have a tendency to increase with the global warming, the frequency of tropical cyclones doesn't show a clear relationship with the global warming, and the research to this scientific question needs a long-term, high-resolution tropical cyclone records. We propose the necessity and feasibility of studying the activity of geological historic tropical cyclones through sedimentary records.
