Circulation Characteristics and Conceptual Model of Rainstorm Processes in the Eastern Foot of the Helan Mountain by Yuying CHEN, Yang SU, Yixing ZHANG, Shanshan YAO, Yin YANG

“…In this study， the rainstorm processes are classified into ordinary rainstorm （50~100 mm）， heavy rainstorm （100~200 mm） and extraordinary rainstorm （more than 200 mm） according to the accumulated rainfall of the rainstorm process.Then， based on 23 rainstorm processes in the eastern foot of the Helan Mountain from 2016 to 2021， the circulation characteristics of different grades of rainstorms are investigated and the corresponding conceptual models are established.The results show that during the rainstorm processes， the westerlies prevail in middle-high latitudes.The rainstorm area is controlled by four airflows， i.e.the 200 hPa westerly airflow， the 500 hPa southwesterly airflow， the 700 hPa southerly airflow and the 850 hPa southeasterly airflow.There is high-level jet and low-level jet in the high and low levels， respectively.The different grades of rainstorms are mainly caused by the different locations and intensities of the South Asia high （SAH） and the Western Pacific Subtropical High （WPSH）.The difference in SAH and WPSH can result in the differences in low-level temperature and humidity， and the stability of atmosphere.The baroclinity is the strongest in the middle levels （700~500 hPa）， and is relatively weak in the low levels （875~700 hPa）.The baroclinity is the strongest for ordinary rainstorm and the weakest for extraordinary rainstorm.For ordinary rainstorm processes， the fronts in the westerlies are the most active， the WPSH is the weakest and southmost， the wet layer is the thickest， the warm cloud layer is the thinnest， and the low-level thermal forcing and atmospheric instability is the weakest.For heavy rainstorm processes， the dynamic forcing is weaker， the WPSH and low-jet is more northward， the low-level thermal forcing and atmospheric instability is relatively strong， the values of convective parameters are relatively large， and the duration， area and magnitude of rainstorm are relatively large.For extraordinary rainstorm processes， the SAH， WPSH and low-level jet are the strongest and northmost， the atmospheric instability is the strongest， the wet layer is the thinnest， and the warm cloud layer is the thickest.The values of convective parameters and vertical wind shear in extraordinary rainstorm processes are 1~3 times that of ordinary and heavy rainstorm processes.The joint effects of the northward advancing low-level jet and the topography of the Helan Mountain favor the occurrence of local rainstorms in the eastern foot of the Helan Mountain.…”

MoT-PSA: a two-layer depth-averaged model for simulation of powder snow avalanches on 3-D terrain by Hervé Vicari, Dieter Issler

“…For snow-avalanche hazard mapping, one needs efficient tools that nevertheless capture the essential physical processes. The code MoT-PSA (Method of Transport – Powder Snow Avalanche) described here is based on the two-layer depth-averaged formulation for mixed snow avalanches developed by Eglit and co-workers in the 1980s but is extended to 3-D terrain and uses a fast numerical scheme based on the method of transport. …”
