提出了一种基于Argo数据的海洋温盐季节特征分析方法,对127°E~130°E、20°N~22°N区域内温度、盐度一年的时间变化特征进行了定性的分析,按其相似性特点进行归类,并分析了它们形成的原因。通过分析可知,Argo数据能够提供中小尺度海洋环境的时间变化特征,主要结果如下:(1)此海区温度、盐度垂直分布类型的时间变化与上层混合强度、太阳辐射及降雨有关;(2)温度垂直分布的时间变化趋势可分为6个阶段,共有9种结构;(3)盐度垂直分布的时间变化趋势可分为3个阶段,共有11种结构。
A method based on Argo data was proposed to analyze seasonal characteristics of ocean warm salt. The seasonal variations of temperature and salinity in 127 ° E ~ 130 ° E, 20 ° N ~ 22 ° N regions were qualitatively analyzed. According to their similarities, they are classified and the reasons for their formation are analyzed. According to the analysis, the Argo data can provide time-varying characteristics of the small and medium-scale marine environment. The main results are as follows: (1) The time variation of vertical distribution types of temperature and salinity in this sea area is related to the upper mixing intensity, solar radiation and rainfall; (2) The time trend of vertical distribution of temperature can be divided into 6 stages, a total of 9 kinds of structures; (3) Vertical distribution of salinity trends can be divided into three stages, a total of 11 kinds of structures.
