“…As discussed in Oh and Ha (2014) in detail, BSISO is related with the onset of East Asian summer monsoon, including Changma, and its active/break (c) Daily temperature probability distribution function averaged over Box B (Siberian region) for winter (November-March) with years of sea-ice less than 50% (blue) and with years of sea-ice more than 50% (red). (d) Same as (c) except averaged over Box C (Korean Peninsula).…”

Weather and climate extremes exert devastating influence on human society and ecosystem around the world. Recent observations show increase in frequency and intensity of climate extremes around the world including East Asia. In order to assess current status of the observed changes in weather and climate extremes and discuss possible mechanisms, this study provides an overview of recent analyses on such extremes over Korea and East Asia. It is found that the temperature extremes over the Korean Peninsula exhibit long-term warming trends with more frequent hot events and less frequent cold events, along with sizeable interannual and decadal variabilities. The comprehensive review on the previous literature further suggests that the weather and climate extremes over East Asia can be affected by several climate factors of external and internal origins. It has been assessed that greenhouse warming leads to increase in warm extremes and decrease in cold extremes over East Asia, but recent Arctic sea-ice melting and associated warming tends to bring cold snaps to East Asia during winter. Internal climate variability such as tropical intraseasonal oscillation and El Niño-Southern Oscillation can also exert considerable impacts on weather and climate extremes over Korea and East Asia. It is, however, noted that our current understanding is far behind to estimate the effect of these climate factors on local weather and climate extremes in a quantitative sense.

“…They also demonstrated that the four modes can be regarded as components of the monsoon ISO, which is the phase locked to the seasonal cycle to a certain degree. Oh and Ha (2015) (hereinafter referred to as OH15) discussed the distinct instability with dynamic-thermodynamic characteristics by underlying their regional features. Following previous studies (Chu et al 2012; OH15), our objective is to provide primary sources to predict the four intraseasonal modes in the EA-WNPSM using the P-E model.…”

“…El Niño‐Southern Oscillation (ENSO), as one of the most remarkable inter‐annual variability tropical signals, strongly influences and modulates the Asian summer monsoon climate (e.g., Huang and Wu, ; Ju and Slingo, ; Lau and Wu, ; Chen, ; Yim et al, ; Sun et al, ; Yuan and Yang, ; He and Wang, ; Gao and Li, ; Oh and Ha, ; Gao et al, ).

The El Niño‐Southern Oscillation (ENSO) has an intimate relationship with Asian summer monsoon precipitation. Previous study pointed out that the most recent 2015–2016 El Niño event is tied with the 1997–1998 and 1982–1983 El Niño events as the strongest event since 1950, which may result in catastrophe in Asian monsoon region. Therefore, in this article, we mainly focus on the anomalous precipitation pattern in the Pan‐Asian monsoon region during MJJ 2016 and its impact factors. Results show that the summer precipitation anomalies display a meridional tripole pattern from north to south in the Pan‐Asian monsoon region during 2016. This pattern indicates that the anomalous increased rainfall is located over the middle–lower reaches of the Yangtze River valley–East China Sea (ECS) and the tropical eastern Indian Ocean–western Maritime Continent, while the anomalous decreased rainfall is located over the South China Sea (SCS)–Philippine Sea. Results suggest that the preceding winter and spring ENSO and the simultaneous summer Maritime Continent sea surface temperature (SST) are the primary impact factors of the pattern of tripole precipitation anomalies in the Pan‐Asian monsoon region during MJJ 2016. The preceding ENSO can intensify the western North Pacific subtropical high (WPSH), which results in the anomalous decrease in precipitation over the Indo‐China Peninsula–Philippine Sea. Meanwhile, more moisture is transported from the northwestern flank of WPSH to the Yangtze River valley–ESC to increase rainfall. In the ENSO decaying summer, the Maritime Continent SST anomalous warming induces an anomalous convergence in situ, which increases the local precipitation. Later, this warming can intensify the WPSH through the local meridional circulation. The north Indian Ocean SST, including Arabian Sea and Bay of Bengal, also has a high relationship with tripole precipitation pattern, but it cannot induce this tripole rainfall pattern, which establishes the linkage through the extending WPSH.
