A Synoptic‐Scale Anticyclone Bridging Typhoon In‐Fa (2021) and the “21·7” Predecessor Rain Event in Henan
Abstract
Abstract An exceptionally heavy rainstorm (the “21·7” Predecessor Rain Event, 21·7PRE) affected Henan Province, China, from 17 to 22 July 2021, coinciding with Typhoon In‐Fa (2021) over the western North Pacific. This study investigates how In‐Fa remotely influenced the 21·7PRE by decomposing atmospheric fields using the multiscale window transform into basic‐scale (>64 days), intraseasonal‐scale (16–64 days), and synoptic‐scale (
