| 摘 要： | 海洋跃层的分析计算是海洋要素值随深度变化的衍生计算,本文基于实际业务化建设经验,不同于以往大量单站温盐观测资料的跃层特征值提取完全由人工分析判断的工作方法,而是将不等距微分法、垂直梯度法和七点二次平滑等算法融合应用到跃层分析工作中,辅以人机交互模式,实现海洋温跃层特征值信息的快速分析计算和产品制作,可大幅缩减人为工作量...

| Abstract: | The thermocline characteristic is derived from the changes of the ocean depth.Different from the pre-vious observations of a large number of single-station temperature and salinity of the thermocline feature extrac-tion entirely by manual analysis,the thermocline characteristic analysis used the method of the inequilateral dif-ferential coefficient,the vertical grads and the Septenary-Quadratic-Smooth filters.Combining with the method of Man-Machine conversation,the thermocline characteristic analysis and c... |
