| 英文摘要 | Over the past few decades, the sea surface temperature (SST) has exhibited increasingly noticeable characteristics of nonlinear and unstable changes in the context of global climate change, particularly in specific local sea areas. This study aims to comprehensively understand the long-term evolution of SST by proposing a novel polynomial-based trend classification model. This model was used for detecting the long-term trends in SST using satellite-based AVHRR SST data from 1982 to 2021, with a special emphasis on the Bohai and Yellow Seas (BYS). It was revealed that the SST of the BYS was increasing by an average of 0.020 ℃/a in the 1982-2021 period, in which time it increased by 0.772 ℃ overall. The magnitude of warming exhibited distinct spatial heterogeneity and seasonal asymmetry. On the spatial scale, the SST trend was higher in the western part than in the eastern part of the BYS. On the seasonal scale, the SST trend was higher during spring and winter than during summer and autumn. During the period of the global warming hiatus around 2012, a substantial nonlinear trend (quadratic or cubic) dominated 58.87% of the area, a concealed nonlinear trend occupied 20.62% of the area, and no considerable trend was detected in 4.21% of the BYS. This study suggests that more attention should be paid to the spatial heterogeneity, seasonal asymmetry, and nonlinear feature of these trends in long-term SST trend evaluation. |
