中文摘要：【目的】研究楚科奇海陆架区夏季(8—10月)温度年际变化。【方法】利用GLORYS12V1再分析数据,并结合海表热通量及断面侧向热通量数据,分析楚科奇海温度年际变化及其与海表热通量和侧向热通量的关系。【结果与结论】楚科奇海东南海域温度最高,约8℃;北部和西部海域多低于3℃;1993—2020年5、29、47 m以及50 m以浅温度的线性增加趋势为0.03~0.07℃/a,且表现出年际变化特征;经验正交函数分解结果显示,各层第一模态均表现出整个研究区域为同位相变化,且各层温度变化具有较大的区域不同;热收支分析结果显示,该时期短波辐射和白令海峡热输送是两个主要热量输入量,影响温度年际变化,而长波辐射、潜热通量以及通过东侧和北侧断面的热量为主要的热量输出量。线性回归分析得出楚科奇海热通量的变化与8—10月平均温度之间的定量关系,可为更好地表征和预测楚科奇海温度变化特征提供参考。

外文摘要：【Objective】To study the interannual variation of the temperature on the Chukchi shelf in August-October.【Method】The temperature reanalysis data(GLORYS12V1),surface heat flux,and lateral heat flux were used to analyze the interannual variation of temperature and its relationship with surface and lateral heat fluxes.【Result and Conclusion】The results show that the temperature in the southeast is higher than that in the west and east,and the highest temperature is 8℃,and the temperature in the northern and western area is mostly below 3℃.The temperatures at the depths of 5 m,29 m,47 m and above 50 m increase by 0.03-0.07℃/a for the linear trend with obvious interannual variation during 1993—2020.The first mode of the EOF analysis shows that the temperature in the entire domain varies in phase,with maximum difference between the warm year and cold year present in different regions for the different depth layers.The heat budget analysis shows that the short wave heat flux and the heat from Bering Strait are two main inputs which affect the interannual variation of temperature,and the long wave heat flux,the latent heat flux,and the heat flux through the eastern and northern sections are the output.The quantitative relation between the heat flux and temperature variation can provide a reference for the manifestation and forecast of the characteristics and variations of the temperature in the Chukchi Sea.
