[1]根据最近的卫星数据提出了新的证据，为量化长期推测的热带气旋对提高海洋初级生产的贡献提供了难得的机会。二零零零年七月，温和气旋启德横过中国南海。在短短三天的停留期间，启德引发了地表叶绿素-a浓度平均增加30倍。据估计，仅这一事件造成的碳固定就为0.8公吨，或南海每年新产量的2-4%。考虑到每年平均有14个气旋经过南海，我们认为长期被忽视的热带气旋对南海每年新产量的贡献可能高达20%-30%。
[1] New evidence based on recent satellite data is presented to provide a rare opportunity in quantifying the long-speculated contribution of tropical cyclones to enhance ocean primary production. In July 2000, moderate cyclone Kai-Tak passed over the South China Sea (SCS). During its short 3-day stay, Kai-Tak triggered an average 30-fold increase in surface chlorophyll-a concentration. The estimated carbon fixation resulting from this event alone is 0.8 Mt, or 2-4% of SCS's annual new production. Given an average of 14 cyclones passing over the SCS annually, we suggest the long-neglected contribution of tropical cyclones to SCS's annual new production may be as much as 20-30%.
