本文研究一家炼油厂发生事故而引起的溢油扩散特性。约有总量为1万立方米的溢油流入濑户内海。事故发生后的一周内,溢油向东方扩散了150公里。很显然,冬季的西北风或西贸易风对这次溢油在海面的扩散起了决定性作用。当溢油扩散至较大范围后,扩散不再是均匀的,而是零散分布。被溢油覆盖的水域面积大于以往任何溢油事故。 This article studies the oil spill diffusion characteristics caused by an accident at a refinery. About a total of 10,000 cubic meters of oil flow into the Seto Inland Sea. Within a week after the accident, oil spills to the east for 150 kilometers. Obviously, the wintering northwest wind or western trade wind played a decisive role in the spread of the oil spill on the sea surface. When spilled oil spreads to a larger area, the diffusion is no longer uniform, but scattered. The area covered by oil spills is larger than any previous oil spill.
