The Analysis of Low-Level Jet and Water Vapor Transportation Characteristics on Continuous Extreme Precipitation in Shanxi from 2 to 6 October 2021 by Yingshu SUN, Yushu ZHOU, Guo DENG, Qing MIAO, Guiqiang QIU

“…From 2 to 6 October 2021， Shanxi experienced the most intense continuous precipitation in autumn in meteorological records.Based on the precipitation observation data of automatic meteorological stations， ERA5 reanalysis data and NCEP GDAS reanalysis data， this study analyzed the circulation situation， low-level jet and water vapor transportation characteristics and water vapor sources of the extreme precipitation.The results indicated that the continuous extreme precipitation process had obvious phased characteristics.In the first stage （from 2nd to 3rd October）， the precipitation occurred in the warm area in front of the cold front and mainly in southern Shanxi.There were obvious convective precipitation characteristics which showed high and strongly fluctuant precipitation intensity.The precipitation of the second stage （from 4th to 6th October） was stable one behind the front which showed low precipitation intensity and long duration， resulting in continuous rainstorm in central and southern Shanxi.The circulation analysis revealed that the abnormally north-located and strong Western Pacific subtropical high and the abnormally south-located and strong West Siberian cut-off vortex constituted a favorable circulation background.During the whole precipitation process， compared with other rainstorm process， the abnormally north-located and strong low-level jet at 700 hPa remained stable which played an important role in the strengthening of low-level convergence， the intense development of vertical upward movement and the continuous water vapor supply.And it was the key to the formation of extreme precipitation.The low-level jet at 850 hPa existed a shorter time but played an important role in the transportation of warm wet air and the construction of unstable layer in southeast Shanxi in the first stage.The main water vapor input level of the heavy rainfall area increased gradually during the precipitation， with the first stage mainly around 850 hPa and the second stage mainly around 700 hPa， which was corresponding to the evolution of the weather situation.The sources of the water vapor in this extreme precipitation were mainly from the South China Sea， the East China Sea and the Yellow Sea， and the transportation path was southeast path， obviously different from other heavy rainfalls which main water vapor sources were mostly from the Bay of Bengal， the Arabian Sea and the South China Sea and the transportation path was southwest path.…”
