为探讨海上搜救目标无动力渔船和落水人员在海水中的漂移规律,对现有海上搜救目标漂移轨迹预测模型进行评估与改进,国家海洋局南海海洋工程勘察中心于2011年2月和4月在广东近岸海域开展了3组模拟人和2组无动力船海上漂移试验.试验发现模拟人与无动力船大部分时刻的漂移轨迹位于下风向的右侧,80%以上的时刻漂移轨迹位于海流流向和下风向的矢量合成区间内.以漂移速度为应变量,流速和风速为自变量进行二元回归分析发现,广东海域的模拟人和无动力渔船的流致漂移参数约为1.0,风致漂移参数分别为0.019和0.038.
為探討海上搜救目標無動力漁船和落水人員在海水中的漂移規律,對現有海上搜救目標漂移軌跡預測模型進行評估與改進,國傢海洋跼南海海洋工程勘察中心于2011年2月和4月在廣東近岸海域開展瞭3組模擬人和2組無動力船海上漂移試驗.試驗髮現模擬人與無動力船大部分時刻的漂移軌跡位于下風嚮的右側,80%以上的時刻漂移軌跡位于海流流嚮和下風嚮的矢量閤成區間內.以漂移速度為應變量,流速和風速為自變量進行二元迴歸分析髮現,廣東海域的模擬人和無動力漁船的流緻漂移參數約為1.0,風緻漂移參數分彆為0.019和0.038.

@@@@To explore the drifting character of fishing boats without working motors and people in the water is the target of maritime search and rescue. For improving and evaluating their target drifting trajectory prediction model, researchers at the South China Sea Marine Engineering Investigation Center of the State Oceanic Administration carried out 2?3 trials in Guangdong coast waters: two times for fishing boats without working motors, and three times for dummy in the water on February 2011 and April 2011. These trials found that the dummy and fishing boats mostly drifted to the right of the downwind, and between the directions of current and downwind more than 80% of the total test times. By binary regression analysis on drift velocity (a dependent variable), current velocity and wind speed (as independent variables), we obtained the following results:current-induced drift parameter is approximately 1.0, wind-induced drift parameters are 0.019 for drifting people and 0.038 for drifting fishing boats.
