| 英文摘要 | While tropical cyclones (TCs) are the primary drivers of extreme precipitation, their interactions with fronts and atmospheric rivers (ARs) substantially modulate rainfall intensity and distribution. This paper investigates these interactions within the hotspot region of western North Pacific (WNP) using an objective attribution method integrated with the Joint Typhoon Warning Center best-track dataset, the ERA5 reanalysis and the Global Atmospheric Rivers Database Version 4. A case study of the super typhoon Lekima in 2019 reveals that the interactions of TCs with fronts and ARs enhance precipitation via moisture convergence and baroclinic instability, resulting in intense precipitation exceeding 18 mm/6 h. Climatological analysis for the period from 1980 to 2019 shows that ARs and fronts frequently co-occur with TCs at median distances of 560 km and 720 km, respectively. TCs interacting with fronts play a key role in the WNP, contributing over 21% and 25% of total and extreme precipitation, respectively. TCs interacting with ARs lead to precipitation at long distances; and compared to TCs in isolation, the median spatial extent of extreme precipitation is increased by 91.84 km. The largest precipitation occurs when TCs interact with both fronts and ARs, with the median values increasing by 1.34 mm/6 h for total precipitation and 1.33 mm/6 h for extreme precipitation. Overall, these findings provide critical insights into the multi-scale drivers of extreme precipitation in the WNP. |
