Recent change in northward migration of the East Asian summer front and increased compound wet–hot conditions

The East Asian summer front (EASF) plays a key role in regional precipitation and heat stress, yet its long-term positional changes remain poorly understood. Using a front-tracking algorithm applied to ERA5 reanalysis (1979–2025), we identify northward migration of the EASF durin...

Muted orbital-scale monsoon variability over the Korean Peninsula

A recent study identified an east-west dipole pattern in Asian Summer Monsoon precipitation and in its oxygen-isotope composition variability in response to orbital forcing (Wen et al., 2024). The Korean Peninsula (KP) is situated near the nodal line of this dipole and should the...
