一次基于实测资料的海上搜救漂浮物的风漂系数优化实验
A parameter optimizing experiment of wind-induced velocity of rescuing floating object in the sea based on an observing project
摘要
Abstract
Based on the data observed from drifting experiments including ship without motor and people in the seawater conducted by the Ningbo center station of forecast center for East China Sea SOA in 2015,assuming the linear relation between the wind-induced velocity and wind velocity,using the optimal algorithm,the optimal parameters of wind-induced velocity are calculated.The results show that the optimal parameters of wind-induced velocity for the ship without motor are 0.046 590 162,0.004 537 790,and for the people in the seawater are 0.044 606 739,-0.003 190 774.When the parameters are optimal,the predicting drifting trajectories are most close to the observed drifting trajectory.The predicting errors grow slowly when the parameters are close to the optimal values,while grow fast when the parameters are far from the optimal values.关键词
