Lagged effects of snow on extreme precipitation in the arid area of Northwest China and the associated mechanisms

Study region: The arid area of Northwest China. Study focus: This study aims to explore the lagged effects of snow on extreme precipitation and the associated mechanisms by using composite analysis and extracting significant areas. Due to the complex terrain of the study area, we have explored the r...

description Study region: The arid area of Northwest China. Study focus: This study aims to explore the lagged effects of snow on extreme precipitation and the associated mechanisms by using composite analysis and extracting significant areas. Due to the complex terrain of the study area, we have explored the response of soil temperature, soil moisture, and various energy changes in different sub-regions, these explorations are conducted in conjunction with the study of lagged effects of snow on extreme precipitation and provide a reference for future climate prediction. New hydrological insights for the region: The response pathways of soil and energy are explored during the impact of snow on extreme precipitation in different significant areas. Latent heat flux is the main energy source, but sensible heat flux and effective radiation can also become the local dominant energy sources due to the influence of many environmental factors. Differences in the paths of influence in different regions will result in different atmospheric circulation anomalies. When the low-value system appears, it is more likely to cause extreme precipitation.
