Abstract

Recently, a new type of El Niño (Warm-Pool El Niño) is more often observed than the conventional El Niño (Cold-Tongue El Niño); each has a distinctive spatial pattern. The two types of El Niño have different teleconnections; therefore their impacts on a specific region can be considerably different. In this study, we focus on statistical relationship between climate variation in Korea and the two types of El Niño. When the two types of El Niño are not separately considered, the statistical relation between climate variables in Korea and the El Niño events is weak in general. When the two types of El Niño are separately considered, however, each type exhibits significant relationship with climate variation in Korea. Therefore, consideration of two types of El Niño separately can potentially improve climate prediction over the Korean Peninsula.
