本文根据南海北部10～26年的月平均海面水温资料,对108°～123°E,18°～26°N范围内的常年海面水温场、水温场的年变化及时间序列结构、异常水温场的特征及其分析的可靠性进行了分析。阐述了水温场的时空结构的统计特征和现象,对其成因做了初步解释,并给出了若干统计结果,为南海北部海面水温实况分析及了解该海域的水文状况,提供了重要依据和参考。
Based on the monthly average sea surface water temperature data of 10 ~ 26 years in the northern part of the South China Sea, the annual variation of the water temperature field and the time series structure, the anomalous water temperature field, the water temperature field in the range of 108 ° ~ 123 ° E and 18 ° ~ The characteristics of the analysis and the reliability of the analysis. The statistical characteristics and phenomena of the spatio-temporal structure of the water temperature field are expounded, and the causes of the water temperature field are preliminarily explained. And some statistical results are given, providing important basis and reference for the real-time analysis of the sea water temperature in the northern South China Sea and understanding the hydrological conditions of the sea area .
