气象和海洋数据时间分辨率差异对渔船漂移轨迹预测精度的影响
The Influence of Different Meteorological and Marine Temporal Resolution Data on the Drift Trajectory Prediction of Fishing Vessel
摘要
Abstract
This study aimed to reveal the influence of different temporal resolution data on the drift trajectory prediction,based on observational data from drift trajectory experiments of fishing vessel in the Wanshan Islands,South China Sea,Both the constrained and unconstrained regression indicated that 10 m wind speed had a significant linear relationship with the wind-induced leeway speed(L)and down-wind leeway speed(DWL).Moreover,the unconstrained regression matched better.Notably,the wind-induced drift parameters calibrated by the unconstrained regression with 30 min resolution data fit-ted the best,compared with other temporal resolution data.Furthermore,the drift trajectory prediction using the AP98 model showed that,the temporal resolution data influenced insignificantly on the experi-ments with small difference between prediction and observation trajectory,but significantly on the ex-periments with large difference.In particularly,the prediction accuracy using 30 min temporal resolu-tion was markedly higher than those for other temporal resolutions,and its overall average error was the smallest.The results can optimize the maritime drift trajectory prediction model,and provide scientific foundation for conducting maritime observation experiments on distress targets and setting the temporal resolution of numerical forecast model.关键词
