英文摘要	This study investigates the summer climate variability over Korea that is associated with diverse features of El Niño-Southern Oscillation (ENSO) evolution. Four different ENSO evolution features were analyzed, and the related Korean climate variability during July and August are investigated. The two evolution phases in which El Niño transitions into La Niña and El Niño develops from a neutral state show roughly similar circulation features in affecting the Korean summer climate, but with opposite signs. During the transition of El Niño into La Niña (after El Niño develops from a neutral state), the positive (negative) western North Pacific anticyclonic circulation anomaly directly affects Korea in August, producing a significant warm (cold) surface air temperature (SAT) anomaly in Korea. Notably, the SAT that occurs in July generally exhibits an opposite tendency to that of August in Korea, displaying subseasonal variations. However, the persistent phases of La Niña and El Niño exhibit distinctive features from the two transition phases mentioned. During the persistent La Niña phase, the Pacific-Japan like atmospheric circulation pattern affects Korea, showing a significant warm SAT anomaly over Korea in July, and a roughly similar situation with opposite signs is observed in the persistent El Niño phase. In these cases, the Korean SAT in August exhibits similar anomalies to July. The distinctive variability in the summer climate of Korea during the diverse ENSO evolution phases presented in this study provides a statistical basis for understanding the Korean summer climate in relation to ENSO. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
