A Time series of upwelling index for Northern South China Sea (1967-2013)

Monthly and hourly upwelling indices have been derived for four locations on the northern/north-eastern coastline of the South China Sea (SCS) (1967-2013) using the standard NOAA-PFEL method. The study locations include: off S.W Taiwan, Off Hanoi, off Fujian, Off Guangdong. Moreover, annual averages and annual anomalies have been calculated for the entire 47-year period for all four locations. This is the first comprehensive and lengthy time-series of upwelling indices in the South China Sea which can enhance understanding of the changes in phenomenon over inter-annual to decadal and multi-decadal time scales, as well as allowing for a comparison of the occurrence of the patterns and magnitude of the process across multiple coastal locations. Acknowledgement: Special appreciation on the development of this dataset goes to Ms. Lynn Dewitt, "Environmental Research Division, Southwest Fisheries Science Center, National Marine Fisheries Service, NOAA".本数据集基于标准NOAA-PFEL方法，针对南海（SCS）北部/东北部海岸线上的四个地点（1967-2013年）计算了月度及小时级上升流指数。研究地点包括：台湾西南部海域、河内附近海域、福建省沿海以及广东省沿海。此外，对于整个47年的研究期间，四个地点的年平均值及年异常值均已计算。该数据集是南海上升流指数的首个全面且详尽的时间序列数据，有助于深入理解现象在年际至多十年甚至数十年时间尺度上的变化，并允许对多个沿海地点上升流模式的发生频率及强度进行比较。致谢：对Ms. Lynn Dewitt及其在NOAA国家海洋渔业服务西南渔业科学中心环境研究部开发本数据集的贡献，表示特别的感谢。
