【摘要】 本文利用Levitus逐月再分析海温资料,通过对南海北部沿几个主要经、纬线剖面的温跃层特征逐月变化进行分析,研究了南海北部海域温跃层的逐月变化特征,并简要分析了其原因。结果发现,该海域跃层深度逐月变化显著,但厚度和强度变化不大;跃层深度、厚度和强度的变化不同步。另外,与外海相比,近岸跃层期短,且跃层较浅、较薄、较强,但逐月变化较为显著。更多还原

【Abstract】 Using the monthly sea water temperature reanalyzed data provided by Levitus,monthly variation characteristics of the thermocline are studied in the Northern South China Sea(NSCS).The results show that,the depth of thermocline varies month by month observably,while the thickness and intensity change little,and these three items vary not in-phase.Comparing with the thermocline in the open sea,the thermocline in the shallow re-gion is shorter-term,shallower,thinner,and stronger,and changes more severely.更多还原
