【 摘 要 】

Based on the metadata, Monthly Sea Surface Temperature (SST) series from nine marine stations over the South China Sea (SCS) are homogeneity detection and correction by Penalized Maximum T Test (PMT) method. The reference stations are developed using surrounding meteorological stations. Correction results show that: (1) The homogeneity detection and correction of marine observation stations should be based on the metadata, meanwhile, fully consider the influence of regional climate change factors. (2) Correlation analysis found that, the air temperature series from the surrounding meteorological stations is currently the optimal reference series. (3) The marine stations has 1∼2 change points average, among them, changes of instrumentation and changes of location environment has great impact on the discontinuities. (4) The trend of the SST over SCS have a more pronounced warming trend during the past 52 years. Correction results indicate that the homogenization research in the SCS has an important meaning for the study of the SCS coast SST changes and climate change.
