摘    要:在湄洲湾试用GNOME溢油模型模拟溢油扩散.先用EFDC建立潮流场,并选用主导风形成常风场,一并输入GNOME建立起溢油模型,模拟涨、落潮过程叠加不同风况下敏感海域的溢油扩散.模拟结果:初始溢油量为100t,扩散到第6小时,8种不同条件下挥发油量都为7.7t,附岸和漂浮油量和为92.3t,其中漂浮油量为6.4~92.0t,相应附岸油量为85.9~0.3t;溢油扩散最大范围为1.3~30.0km。,90%置信区间为2.0~56.0km。,最大距离为1.2~14.6km;与前人模拟溢油扩散结果相比基本一致.经分析,溢油扩散主要受3个方面影响:(1)岸线走向:当岸线靠近油膜漂移的路线时,大量油膜附着在岸上,扩散范围较小;(2)风况与流场关系:如果两者方向一致,油膜会扩散较远;(3)风区长度:风区越长,油膜扩散范围越大.总之,建立GNOME溢油模型较好地模拟了溢油扩散趋势,对溢油应急响应具有参考作用.

关 键 词:海洋环境科学  GNOME溢油模型  模拟  溢油扩散  湄洲湾

Abstract:The current study simulated the spread of an oil spill in Meizhou Bay,China,using the GNOME computer program,an oil-spill trajectory model developed by the United States National Oceanic and Atmospheric Administration(NOAA).Tidal current field modeled by the environmental fluid dynamics code(EFDC) and the constant wind field established by the annual dominant wind(NE,7.3 m/s) and the summer dominant wind(SW,4.6 m/s) were used as parameters for GNOME to develop a Meizhou Bay oil-spill model.Some parameters u...
