Global climate change has strongly increased the worldwide frequency of extreme heat (EH) in recent decades. South Korea and southern-central Japan are also frequently affected by extreme heat, and the extreme heat in these two regions tend to occur simultaneously. A scientific collaboration of climatologists examined the large-scale circulation leading to the concurrent extreme heat over South Korea and Southern-Central Japan. Their results have been published in Journal of Climate recently.
