本文统计分析了渤海气温异常月份与埃尔－尼诺过程的关系，结果得出：在埃尔－尼诺年及其前后一年，渤海气温异常冷月占优势；在埃尔－尼诺持续期内，春季渤海气温出现异常冷月的百分率高达７３％。埃尔－尼诺与渤海气温异常关系的分析结果，表明了在海－气相互作用过程中，二者互为因果关系的事实。 This paper statistically analyzes the relationship between the abnormal Bohai Sea temperature and the El Niño process. The results show that during El Niño years and around the year, the Bohai Sea temperature anomalies prevail over the cold months and El Niño continues During the period, the percentage of unusually cold months in the spring Bohai Sea was as high as 73%. The results of the analysis of the relationship between the El Niño and the Bohai Sea temperature anomaly show the fact that the two are causal relationship to each other during the sea-atmosphere interaction.
