East Asia's summer rain belt has shifted north over decades, reshaping rain and heat risks

AI Summary

Researchers from KAIST and the APEC Climate Center found that East Asia’s summer rain front has shifted north by more than 200 km in late summer over the past half-century. The change could increase the Korean Peninsula’s exposure to simultaneous heavy rain and heat stress, highlighting the need to coordinate flood and heat-illness preparedness.

A joint research team from KAIST and the APEC Climate Center has found that the East Asian summer front has migrated north over the past half century, with the shift exceeding 200 km (124 miles) in late summer. This raises the risk that the Korean Peninsula will experience heavy rain and heat stress at the same time. The findings suggest that summer disaster planning should address flood prevention and heat-illness management together, through late September.
