西北非上升流锋研究具有较高的海洋学研究价值和军事应用价值,本文主要通过WOA13数据对西北非上升流锋区锋面分布、锋强度水平和垂直变化特点以及相应的季节变化特点等时空变化特征进行研究,旨在弥补国内外对于西北非上升流锋区研究的不足。分析认为,西北非上升流锋轴线大致沿海岸分布,且随着深度增加逐渐远离海岸;锋轴线上锋强度在水平和垂直分布不均匀,水平方向上强度大的区域集中在23°N~25°N之间,垂直方向上在水深50~150m范围内锋轴线强度较大;锋的季节变化主要表现在温度锋强度季节差异上。
In this paper, the temporal and spatial changes of frontal distribution, frontal intensity and vertical variation and the corresponding seasonal variation characteristics of WFI in northwestern China were mainly analyzed by WOA13 data in this study, which has a high value of oceanographic research and military application. Characteristics of the study, designed to make up for the lack of research on the rising Northwest Africa flow at home and abroad. The analysis shows that the northwest upcounter flow frontal axis distributes roughly along the coast and gradually moves away from the coast with the increase of depth. The frontal strength of the frontal axis is unevenly distributed horizontally and vertically, and the strong horizontal region concentrates at 23 ° N ~ 25 ° N in the vertical direction in the depth of 50 ~ 150m frontal axis intensity is greater; seasonal changes in front mainly in the temperature front of the seasonal differences in strength.
