Relationship between Arctic Sea Ice in Autumn and Subsequent July Air Temperature over East Asia and the Western North Pacific

Influence of Okhotsk Sea blocking on summer precipitation over South Korea

“…According to previous studies, extreme droughts in South Korea occurred in 1927Korea occurred in -1930Korea occurred in , 1938Korea occurred in -1945Korea occurred in , 1951Korea occurred in -1952Korea occurred in , 1967Korea occurred in -1969Korea occurred in , 1994Korea occurred in -1996Korea occurred in , and 2013Korea occurred in -2015, caused mainly by successive shortages of summer rainfall for multiple years (Kim et al, 2011;Zhang and Zhou, 2015;Kwon et al, 2016). In an attempt to understand drought in South Korea better, many studies have investigated the characteristics, such as spatiotemporal variation (Min et al, 2003;Azam et al, 2018;Kwon et al, 2019), the relationship with preceding climate conditions (Choi et al, 2009(Choi et al, , 2011, and future projection (Im et al, 2012;Choi et al, 2016;Lee et al, 2019). Furthermore, potential evapotranspiration (PET), as a function of temperature, is another climate factor impacting drought conditions (Easterling et al, 2007;Im et al, 2012).…”
