Precipitation events have been occurring more frequently in the hyper-arid region of Taklamakan Desert (TD) under recent climate change. However, this water-limited environment, microphysical characteristics precipitation, as well their link to rainfall intensity, remain unclear. To address this, study utilizes dual-frequency precipitation radar (DPR) data Global Measurement (GPM) satellite from 2014 2023 analyze different types (stratiform and convective) TD during summer. The results show that liquid water path (LWP) is a key factor influencing type: when LWP insufficient, stratiform likely occur (84.1%), while convective difficult (15.9%). Microphysical process analysis indicates abundant low-level moisture leads growth particles primarily through collision–coalescence (59.7%), resulting larger raindrop diameters (1.7 mm) lower concentrations (31.9 mm−1 m−3). In contrast, with limited LWP, involves melting breaking-up high-level ice-phase particles, leading smaller (1.2 higher (34.3 warm rain plays significant role formation both precipitation. greater (lesser) amount (smaller) contribution (break-up) processes, diameter intensity.

Abstract. Flash floods typically occur suddenly within hours of heavy rainfall. Accurate forecasting flash in advance using the two-dimensional (2D) shallow water equations (SWEs) remains a challenge, due to governing SWEs being difficult-to-solve partial differential (PDEs). Aiming at shortening computational time and gaining more for issuing early warnings floods, constructing new relationship between storage outflow rainfall–runoff process is attempted by assuming catchment as system. Through numerical simulations diffusion wave (DW) approximation SWEs, discharge are found be limited envelope lines, discharge/water-depth lines during rising falling showed grid-shaped distribution. Furthermore, if regarded semi-open system, then there nonlinear inside average depth outlet depth, namely, ratio curve, which resembles shape plume. In case an open channel without considering spatial variability, curve three values (i.e., upper, steady, lower limits), independent meteorological (rainfall intensity), vegetation (Manning's coefficient), terrain (slope gradient) conditions. Meteorological, vegetation, conditions only affect size plume changing its shape. Rainfall, especially weak rain when rainfall intensity less than 5.0 mm h−1), significantly affects fluctuations ratio, can divided into modes: Mode I (inverse S-shape type) beginning stage, II (wave duration III (checkmark end stage. Results indicate that determination under different geographical scenarios will provide ideas simulation warning floods.
