Simulated ocean currents from ocean circulation models along with the surface winds are generally used to force an oil spill trajectory model. Ocean circulation is a key factor in determining the drift of the spilled marine pollutants. The simulations of the drift pattern of spilled oil, when forced by the ocean currents from two ocean models, are presented here. Merchant Vessel (MV) Rak sunk at 72.4865°E, 18.7715°N, on 4 August 2011. As per the information from Indian Coast Guard, approximately 122.5 tons of fuel oil was spilled from the vessel from 5 August 2011 to 12 August 2011. An oil spill trajectory model, General NOAA Operational Modeling Environment (GNOME), was used to simulate the oil drift pattern from MV Rak from 1000 hours of 5 August 2011 to 1300 hours of 12 August 2011. GNOME was forced with winds from European Centre for Medium Range Weather Forecast (ECMWF) and ocean currents from Indian Ocean Forecasting System (INDOFOS) and High-resolution Operational Ocean Forecasting and reanalysis System (HOOFS). We found that the oil drift pattern obtained when forced with ocean currents from HOOFS was in better agreement with the actual track, compared to the one obtained while using INDOFOS currents.

来自海洋环流模型的模拟洋流以及地表风通常被用于强迫溢油轨迹模型。海洋环流是确定溢流的海洋污染物漂移的关键因素。此处介绍了在两个海洋模型的洋流推动下，溢油的漂移模式的模拟。商船（MV）Rak于2011年8月4日在72.4865°E，18.7715°N下沉。根据印度海岸警卫队的信息，从2011年8月5日至2011年8月12日，约有122.5吨燃油从船上溢出。使用漏油轨迹模型（通用NOAA运行建模环境（GNOME））模拟了MV Rak从2011年8月5日的1000小时到2011年8月12日的1300小时的油漂移模式。GNOME受到来自欧洲中程天气预报中心（ECMWF）的风和来自印度洋预报系统（INDOFOS）和高分辨率可操作海洋预报与再分析系统（HOOFS）的洋流的强迫。我们发现，与使用INDOFOS海流获得的油流模式相比，由HOOFS施加洋流强迫获得的油流模式与实际航迹更好地吻合。
