摘要: |
采用基于“拉格朗日”粒子追踪方法的油粒子数值溯源模式, 引入天气预报中的“集合预报”方法, 考虑气象、海洋环境背景场误差因素, 研究无主溢油源的集合预测方法。对某次渤海中西部溢油溯源事件的数值模拟结果表明, 溢油源集合预测分析结果与溢油源实际调查情况相符, 表明无主漂油源集合预测方法科学、结论可信。 |

Study on the ensemble forecast of oil spilled sources |
|
Abstract: |
Inthis paper, the tracing model of oil particle based on the theory of Lagrange method was studied.With reasonable design of the environmental background field, the model was used to simulatedifferent scenarios. The statistical distribution of the ensemble of oil particles was analyzed to determine the possible scope of the oil source. The tracing simulation of scenario of oil spill in Midwestern of the Bohai Sea in 2010 demonstrates that, the result of ensemble forecast is consistent with the actual survey, suggesting that our ensemble tracing model is reliable and operational scientifically. |
Key words: oil spill tracing mode ensemble forecast |
