Humid heat poses a greater threat when concurrent with atmospheric river over Eastern China (opens in new tab)

The linkage between atmospheric rivers (ARs) and humid heat (HH) remains a largely unexplored research domain. This study detected 834 humid heat days (HHDs) in eastern China from 1979 to 2018, with above half of the HHDs coinciding with ARs during the boreal summer. Compared to HH not associated with ARs, those related to ARs exhibit a broader impact area and greater severity. The western North Pacific subtropical high (WNPSH)-affected and low pressure system (LPS)-affected HH types are iden...
