Abstract During the presummer rainy season (April–June), southern China often experiences frequent occurrences of extreme rainfall, leading to severe flooding and inundations. To expedite efforts in improving quantitative precipitation forecast (QPF) Meteorological Administration (CMA) initiated a nationally coordinated research project, namely, Southern Monsoon Rainfall Experiment (SCMREX) that was endorsed by World Organization (WMO) as development project (RDP) Weather Research Programme...
Abstract Two catastrophic extreme precipitation events in July 2021 and August 1975 caused tremendous damages deaths Henan, one of the most populated provinces China. Revealing relationship between large‐scale circulation patterns extremes is vital for understanding physical mechanisms providing potential value improving prediction hence reducing impacts. Here, nine are identified July–August using self‐organizing map. We find daily under fifth pattern (P5), characterized with strongest...
Forecast uncertainties and physical mechanisms of a quasi-linear extreme-rain-producing mesoscale convective system (MCS) along the Meiyu front in East China, during midnight-to-morning hours on 8 July 2007, are studied using ensembles 24 h convection-permitting simulations with nested grid spacing 1.11 km. The reveal strong sensitivity to initial state despite synoptic environment being favorable for heavy rainfall production. Linear changes less skillful member's toward that member lead...
The paths and sources of moisture supplied to South China during two periods the presummer rainy season (April–June) 1979–2014, i.e., before after onset summer monsoon over Sea (SCS), are investigated by using Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model. During premonsoon-onset period, transport trajectories clustered into 6 groups, with four ocean-originating providing 83.9% continent-originating (originating Lake Baikal Persian Gulf) contributing remaining 16.1%...
This paper reviews the major progress on development of science and prediction heavy rainfall over China since beginning reform opening-up new (roughly between 1980 2019). The research physical mechanisms is summarized from three perspectives: 1) relevant synoptic weather systems, 2) in sub-regions China, 3) induced by typhoons. application forecasting techniques for are terms numerical objective methods. Greatly aided rapid meteorological observing technology substantial improvement...
ABSTRACT The spatial and temporal characteristics of abrupt heavy rainfall events (AHRE: defined as 3‐hr amount ≥50 mm at least one 1‐hr ≥20 during the 3 hr) over southwest China (SWC) between 1981 2017, including their occurrence frequency, intensity, duration, were investigated based on hourly data collected from 468 rain gauge stations. frequency these AHREs exhibited large variability among different regions. We distinguished three regions with high rates AHREs: Sichuan Basin (subregion...
The mesoscale Weather Research and Forecasting (WRF) model has been widely employed to forecast day-ahead rainfalls. However, the deterministic predictions from WRF incorporate relatively large errors due numerical discretization, inaccuracies in initial/boundary conditions parameterizations, etc. Among them, uncertainties parameterization schemes have a huge impact on forecasting skill of rainfalls, especially over Sichuan Basin which is located east Tibetan Plateau southwestern China. To...
Abstract A Lagrangian model—the Hybrid Single-Particle Integrated Trajectory model (HYSPLIT)—is used to quantify changes in moisture sources and paths for precipitation over North China’s Henan Province associated with tropical cyclone (TC) the western Pacific (WNP) during July–August of 1979–2021. During TC-active periods, an anomalous WNP enhances southeasterly reduces southwesterly transport Henan. Accordingly, compared TC-inactive contributions from Ocean (PO), eastern China (EC), local...
During the past three years, new insights have been gained into convective features and microphysical characteristics of heavy rainfall in South China, which is a typical monsoon coastal area.Such improved understanding closely related to rapid progress application advanced remote sensing techniques, particular upgrade dual-polarization function operational weather radars China.This paper reviews representative studies since approximately 2019 aspects.First, spatiotemporal distribution...
Knowledge of the microphysical characteristics precipitation plays a significant role in meteorology, hydrology, and natural hazards management, especially western Sichuan Basin (WSB), which is located east Tibetan Plateau (TP) southwestern China thus has unique terrain conditions weather systems. Nonetheless, literature regarding raindrop size distribution (RSD) WSB still very limited. This work investigates RSD temporal variations site (Chengdu, CD) by employing three years...
