Abstract Observational data indicate increasing trends of surface ozone (O 3 ) in China, despite emission controls that have resulted reductions precursor emissions. Here, we explore the cause this contradiction, through analysis observations (2014–2019) China and historical observation record United States (US, 1990–2019). Our observation‐based indicates nitrogen oxides (NO x emissions led to increase O North Plain (NCP) Yangtze River Delta (YRD) around 8 ppb. However, NO shift chemical...
Abstract The Tibetan Plateau (TP) impacts local and remote atmospheric circulations, wherein it mechanically thermally affects air masses or airflows. Moreover, the TP provides a key channel for substance transport between troposphere stratosphere. This study reviews recent advances in research regarding land–atmosphere coupling processes over TP. experiences climate warming wetting. Climate has caused glacier retreat, permafrost degradation, general increase vegetation density, while...
Abstract The non-hydrostatic global variable resolution model (MPAS-atmosphere) is used to conduct the simulations for South Asian Summer monsoon season (June, July, and August) in 2015 with a refinement over Tibetan Plateau (TP) at convection-permitting scale (4 km). Two experiments different topographical datasets, complex (4-km) smooth (60-km) topography, are designed investigate impacts of complexity on moisture transport precipitation. Compared observations reanalysis data, simulation...
Abstract. Most previous modeling studies about black carbon (BC) transport and its impact over the Tibetan Plateau (TP) conducted simulations with horizontal resolutions coarser than 20 km that may not be able to resolve complex topography of Himalayas well. In this study, two experiments covering all Weather Research Forecasting model coupled Chemistry (WRF-Chem) at resolution 4 but different datasets (4 smooth topography) are for pre-monsoon season (April 2016) investigate impacts on...
Over the Tibetan Plateau, solar heating often produces strong convective instability in atmosphere. Using 3 years (1998–2000) of Tropical Rainfall Measuring Mission (TRMM) precipitation radar data, our investigations revealed a tower mast shape over Plateau both height‐longitude and height‐latitude cross‐sections. High rain rate center is located above 6km as penetrating into mid‐troposphere against nearby background, implying unique latent source injecting directly to middle Results...
Abstract The simulations of summertime diurnal cycle precipitation and low-level winds by the Community Atmosphere Model, version 5, are evaluated over subtropical East Asia. evaluation reveals physical cause observed rainfall variation in Asia points to source model strengths weaknesses. Two versions with horizontal resolutions 2.8° 0.5° used. models can reproduce phase large-scale Asia, an enhanced southwesterly early morning. Correspondingly, successfully simulated stratiform a maximum...
Abstract. Regional heavy pollution events in eastern China (110–122° E, 28–40° N) are causing serious environmental problems. In this study, the relationship between degree of regional and patterns large-scale atmospheric circulation over October is investigated using 10-year (2001–2010) Terra/MODIS aerosol optical depth NCEP reanalysis data by both case study composite analysis. Eighteen polluted 10 clean episodes selected categorised into six types three respectively. Generally speaking,...
Abstract We identified precipitating systems from May to August 2016 using data the Global Precipitation Measurement mission Dual-frequency Radar instrument. Then, this set of cases, Himawari-8 10.4-μm brightness temperature before and after each precipitation event were used identify three life stages clouds: a developing stage, mature dissipating stage. Using statistical analysis two case studies, we show that at different clouds have systematic properties, including area precipitation,...
Mineral dust is the most important natural source of atmospheric ice nuclei (IN) which may significantly mediate properties cloud through heterogeneous nucleation and lead to crucial impacts on hydrological energy cycle. The potential IN effect top temperature (CTT) in a well-developed mesoscale convective system (MCS) was studied using both satellite observations resolving model (CRM) simulations. We combined from passive spectrometer, active radar, lidar, wind field simulations CRM...
Abstract. Estimation of land surface heat fluxes is important for energy and water cycle studies, especially on the Tibetan Plateau (TP), where topography unique land–atmosphere interactions are strong. The heating conditions also directly influence movement atmospheric circulation. However, high-temporal-resolution information plateau-scale has been lacking a long time, which significantly limits understanding diurnal variations in interactions. Based geostationary polar-orbiting satellite...
The Fuhe River Basin in Jiangxi Province, China. Global climate change and intensified human activities are making the hydrological processes at experiencing dramatic changes. Although some studies have investigated their individual impacts on basin-scale water resources, combined effects hydrology received little attention. In this study, future scenarios were constructed for three periods, based five global model outputs (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6) a...
In this study, we analyzed the vertical precipitation profiles in tropics derived from radar onboard Tropical Rainfall Measuring Mission satellite. For a given rain type, principal component analysis was done to all that have similar rainfall rate at 2 km altitude. It is found first can explain more than 80% of variations profiles, and reconstructed components closely resemble ensemble mean. therefore concluded mean are representative typical pattern structure. The for deep convections...
Using the tropical rainfall measuring mission (TRMM) Precipitation Radar (PR) observations combined with surface rain gauge data during 1998–2006, robust diurnal features of summer stratiform and convective precipitation over southern contiguous China are revealed by exploring variations rate profile. The exhibits two distinguishing phases: late-night (2200–0600 LST) late-afternoon (1400–2200 LST), dependent on location, type duration time. Generally, maximum highest profile occur in...
Abstract Rain-type statistics derived from Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) standard product show that some 70% of raining pixels in the central Tibetan Plateau summer are stratiform—a clear contradiction to common knowledge rain events during this region mostly convective, as a result strong atmospheric convective instability resulting surface heating. In examining vertical distribution stratiform rain-rate profiles, it is suspected TRMM PR algorithm...
Abstract [1] Using Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation data from June 2006 to December 2009, the temperature structure tropopause height over Tibetan Plateau (TP) is studied in this paper. The TP warmer experiences a lager magnitude of change than that same latitudinal plain area (hereinafter referred as Plain) at level lower troposphere. lapse rate (LRT) shows strong correlation with thermal properties atmosphere. Its variation...
