Particulate air pollution has been suggested as the cause of recently observed decreasing trends 10 to 25% in ratio between hilly and upwind lowland precipitation, downwind urban industrial areas. We quantified dependence this orographic-precipitation enhancement factor on amounts aerosols composed mostly free troposphere, based measurements at Mt. Hua near Xi'an, central China. The precipitation can be decreased by 30 50% during hazy conditions, with visibility less than 8 kilometers...
Abstract This paper provides a summary of the assessment report World Meteorological Organization (WMO) Expert Team on Weather Modification that discusses recent progress precipitation enhancement research. The has been underpinned by advances in our understanding cloud processes and interactions between clouds their environment, which, turn, have enabled substantial developments technical capabilities to both observe simulate from microphysical mesoscale. We focus two types most commonly...
Abstract The atmospheric water resources (AWR) in China have evident regional characteristics. In order to scientifically and rationally exploit the AWR different regions of China, we divided into seven based on ERA‐5, CloudSat data, so on. Such characteristics as vapour, cloud characteristics, (CWR), precipitation efficiency hydrometeors (PEh), exploitation potential CWR were studied this article. Some results summer are shown. (a) There relatively more precipitation, richer stronger vapour...
Effects of weather modification operations on precipitation in target areas have been widely reported, but little is specifically known about the downwind (extra-area) effects China. We estimated extra-area effect an operational winter (November–February) aircraft cloud-seeding project northern Jiangxi Province eastern China by using a revised historical target/control regression analysis method based data winter. The results showed that overall seasonal average rainfall at stations...
Abstract The atmospheric river (AR) is a long, narrow, and transient corridor of strong horizontal water vapor transport. Various AR detection methods have been proposed, which introduced significant uncertainty to the identified characteristics. This study has designed data fusion algorithm merge 12 sets different global regional identification algorithms published by Atmospheric River Tracking Method Intercomparison Project (ARTMIP) covering period from 1980 2016. It aims conduct frequency...
The Tibetan Plateau is a unique location for studying the global climate and China's severe weather. precipitation on can be studied conveniently with Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI). It shown that TMI brightness temperature at 85 GHz in vertical polarization (TB85V) negatively correlated to surface rain rate, but very low value of TB85V does not correspond intense rates Plateau, result different from what observed other areas world. For retrieval TMI,...
Based on 55 years (from 1961 to 2015) of ground‐based hailstorm and atmospheric sounding observations, the climatological characteristics hailstorms in China, along with potential influencing factors, were analysed. We found that exhibit large spatial temporal variability, peak occurring spring south summer north China. The Tibetan Plateau (TTP) is a region high frequency. Overall, frequency has decreased over years, although there was an increase from 1985. In terms diurnal while peaks...
Abstract With the abrupt and significant drop of PM 2.5 concentrations during lockdown in 2020, hourly direct radiation ( R dir ) at surface substantially increased East China, such as Zhengzhou, Wuhan Baoshan, with maximum enhancement 86% Wuhan. Most these stations had decreased diffuse dif except Zhengzhou. Zhengzhou both enhanced , well reduced but still high concentrations, indicating atmospheric particles were more scattering this region. At Beijing Harbin North Northeast...
Understanding the characteristics of cloud water resource (CWR) and precipitation efficiency hydrometeors (PEh) is imperative for application CWR in Northwest China. The atmospheric precipitable (PW) all four seasons clouds PEh summer were studied with ERA-5 CloudSat data this region. results show that topography, especially Tibetan Plateau, exerts significant impacts on PW summer, since large amounts are distributed along mountain ranges. study region divided into typical areas: monsoon...
The ability of the Tropical Rainfall Measuring Mission Microwave Imager (TRMM/TMI) for rainfall and flooding detection has been demonstrated in this study. A dynamic cluster K-mean method was presented to classify surface types rain areas.Based on TMI measurements observations during Huaihe River Basin Energy Water Cycle Experiment, scattering index over land (SIL) developed a rate (RR) retrieval algorithm established, which RR is function SIL PCT85 (polarization corrected temperature at 85...
Understanding the spatial and temporal variation characteristics of atmospheric water resources in each region China is essential for their exploitation. In this study, we focus on precipitable (PW), cloud parameters, (CWR), precipitation efficiency hydrometeors (PEh) as well possible influencing factors summer using ERA5 MODIS data. The results showed that: (1) past 42 years, PW increased significantly northwest Tibetan Plateau regions, both cover total column content decreased northern...
To investigate the topographic effects on precipitation in Liupan Mountains Area of Northwest China, three micro rain radars, located at a ridge, west valley, and east valley area, respectively, were used to observe processes. By comparing characteristics stratiform sites, it was found that (i) effective radar reflectivity characteristic falling velocity hydrometeors ridge larger than those valley; (ii) diameter density solid slightly (iii) there also higher occurrence frequency graupel...
In a private/ public work was allowed to put in motion the program of cloud seeding, multiregional and multispectral program, created by common need face drought. this sense because emergency,tThe regions Atacama, Coquimbo, Valparaiso O’Higgins, decided establish programs increase level rainfalls. The present study has aim, evaluation this, an interrelationship analysis used compare performance rainfalls water (volume flow) control basin, case, Maipo River, with basin where plan implemented,...
