摘要
海上能见度是影响舰船航行的主要水文气象要素之一,研究中国海海域能见度的航海气候区划,是民用、军用部门均感兴趣的一个课题。本工作以长达50年的船舶气象观测资料为根据,应用非线性映射法统计处理了这些数据,作出了中国海能见度的航海气候区划,并绘出相应的区划图,从而对中国海海域的能见度分布特征有清晰的概念。最后对这种区划法的合理性进行评估,获得了明确的结论。
The visibility at sea is one of the important hydrometeorological factors which influence the safety of navigating ships. It is an interesting problem for both in civil and naval organism related to research on the visibility of China Sea. By using the meteorological data observed by merchant navigators for the last fifty years and applying the nonlinear mapping method to statistically process these data,the marine climatic divisions of visibility in the China Sea and its division maps are obtained. Finally with the reasonability of this marine climatic divisions assesed, we have a clear conclusion.
