The Remote Effect of Binary Typhoon Infa and Cempaka on the “21.7” Heavy Rainfall in Henan Province, China

Abstract: During July 17-22, 2021, a record-breaking extreme rainfall occurred across Henan Province, with 6-day accumulated rainfall and the maximum daily rainfall reaching 1122.6 and 624.1 mm, respectively. In particular, the first-ranked Zhengzhou National Automatic Weather Station has an hourly rainfall intensity of up to 201.9 𝐴𝐴 𝐴𝐴𝐴𝐴 𝐴 −1 (at 0800-0900 UTC July 20), which broke the historical record in the Chinese inland (198.5 𝐴𝐴 𝐴𝐴𝐴𝐴 𝐴 −1 , Linzhuang, 5 August 1975). Such a historic rainfall event … Show more

“…Our result indicated that the strong low‐level easterly airflow between the WPSH and Typhoon In‐Fa plays an essential role in the HnHRE, which is supported by some recent research (Deng et al., 2022; Luo et al., 2022; Y. Nie & Sun, 2022). Unique from the previous literature, the contribution of the WPSH and In‐Fa to the HnHRE is reasonably and quantitatively evaluated in this study, which pointed out that the HnHRE occurred with the aid of the highly favorable configuration of WPSH and In‐Fa circulations and their cooperation.…”

“…The terrestrial and oceanic moisture over southern China-western North Pacific was both crucial for the extreme precipitation event over Henan (Nie and Sun, 2022). The main moisture transport was driven by airflows on the peripheries of binary tropical typhoon (BT) In-fa and Cempaka (Deng et al, 2022;Sun et al, 2023). The event produced well-organized mesoscale convective systems whose unique dynamic structure contributes significantly to record-high hourly rainfall (Yin et al, 2021).…”

“…The HnHRE caused nearly 400 people to be dead and missing and $17.65 billion direct economic loss. Recent studies indicated that the HnHRE took place in an anomalous synoptic circulation pattern, namely, the coexistence of a northwestward-shifting WPSH, Typhoon In-Fa (2021) over the East China sea, and Typhoon Cempaka (2021) over the South China Sea (Deng et al, 2022;Fu et al, 2022;Nie & Sun, 2022;Xu et al, 2022). Rao et al (2022)…”
