【摘要】：为准确评估海洋环境对海盗活动的影响及建立有效的海盗活动预警模型,按照海盗活动分布区域和海洋环境特征将索马里-印度洋海域划分为3个区域,在此基础上借助卫星数据对相关区域9a的海盗活动受海洋环境参数的影响进行了长时间尺度的匹配分析。研究结果表明,海洋中尺度现象(如中尺度涡)及其他特定海洋环境参数对海盗活动的范围和方式有重要影响,尤以有效波高(海况)、海面风速、海表流速及海表温度相关性影响较大。单独评估结果表明:当有效波高大于2.5m时,海盗很难活动;海面风速大于11m/s可确保海盗对商船没有威胁;海表流速小于0.3m/s时较适宜海盗活动。
[Abstract]:In order to accurately assess the impact of the marine environment on piracy and to establish an effective early warning model for piracy, the Somali-Indian Ocean area is divided into three regions according to the distribution of piracy and the characteristics of the marine environment,On the basis of this, a long time scale matching analysis is carried out on the influence of marine environmental parameters on the piracy activities in the relevant area 9a with the aid of satellite data.The results show that ocean mesoscale phenomena (such as mesoscale vortices) and other specific marine environmental parameters have important effects on the range and manner of piracy, especially effective wave heights (sea conditions, sea surface wind speeds,The correlation between sea surface velocity and sea surface temperature is significant.The individual evaluation results show that when the effective wave height is more than 2.5 m, it is very difficult for pirates to operate; when the sea surface wind speed is greater than 11m/s, there is no threat to merchant ships, and when the sea surface velocity is less than 0.3m/s, it is more suitable for piracy activities.
