Abstract. Understanding the mechanism of haze formation is crucial for development deliberate pollution control strategies. Multiphase chemical reactions in aerosol water have been suggested as an important source particulate sulfate during severe (Cheng et al., 2016; Wang 2016). While key role has commonly accepted, relative importance different oxidation pathways aqueous phase still under debate mainly due to questions about pH. To investigate spatiotemporal variability pH and winter North...
Abstract Tectonic research of the Tibetan Plateau has long focused on its deformation style and mechanisms. The 2008 Mw7.9 Wenchuan earthquake ruptured Longmen Shan fault located at eastern rim plateau excited a viscoelastic response lithosphere. We infer three‐dimensional (3D) rheological structure Tibet from modeling nine years postseismic displacements observed by GPS. Our solution provides tight constraints lower‐crustal upper‐mantle steady‐state viscosities Songpan‐Ganzi Terrane as (5.0...
Abstract. Rapid urbanization throughout eastern China is imposing an irreversible effect on local climate and air quality. In this paper, we examine the response of a range meteorological quality indicators to urbanization. Our study uses Weather Research Forecasting model coupled with chemistry (WRF/Chem) simulate impacts four hypothetical scenarios fixed surface pollutant emissions during month July from 2008 2012. An improved integrated process rate (IPR) analysis scheme implemented in...
Using a compilation of 6980 heat flow measurements, we produce new map for the Chinese continent and its adjacent areas. We develop an objective integrated method to interpolate data, taking into account both uniformity within geological units coherency regional flow. The geologic are outlined based on Zhang et al.'s active tectonic block model. Our model is presented in two formats: contour dataset with values 1 × 1° grid areas, reflecting detailed variations some regions. Also provided...
Abstract The seismicity rate in the southwestern Sichuan basin, China, dramatically increased after 2014. associated moderate earthquakes may have been induced by salt mining or shale gas exploration. location of seismogenic faults causing these has not confirmed, resulting a lack understanding earthquake mechanisms study area. detailed structural characteristics pre-existing faults, which are typically responsible for seismicity, unclear. In this study, we used high-resolution seismic...
Latent heating profiles associated with three TOGA COARE active convective episodes (December 10-17 1992; December 19-27 and February 9-13 1993) are examined using the two-dimensional version of Goddard Cumulus Ensemble (GCE) Model, retrieved by Convective Stratiform Heating (CSH) algorithm. The following sources rainfall information input into CSH algorithm: Special Sensor Microwave Imager (SSM/I), shipborne radars GCE model. Diagnostically determined latent calculated 6 hourly soundings...
Abstract Impoundment of the Zipingpu reservoir (ZR), China, began in September 2005 and was followed 2.7 years later by 2008 M w 7.9 Wenchuan earthquake (WE) rupturing Longmen Shan Fault (LSF), with its epicenter ~12 km away from ZR. Based on poroelastic theory, we employ three‐dimensional finite element models to simulate evolution stress pore pressure due impoundment, effect Coulomb failure LSF. The results indicate that impoundment formed a front slowly propagated through crust fluid...
Abstract Induced earthquakes are becoming a significant issue. Several destructive induced (Ms ≥5.0) have occurred in shale gas fields located at the southwestern Sichuan basin, China, recent years. Specifically, two moderate with magnitudes of Ms 5.4 (occurred on 8 September 2019) and 5.2 18 December exceeded largest earthquake ever recorded Weiyuan. It remains unclear which seismogenic faults were responsible for events due to insufficient knowledge subsurface structure contradictory...
The Beaufort Sea high (BSH) plays an important role in forcing Arctic sea ice and the Gyre. This study examines variability long-term trends of atmospheric circulation over Chukchi Seas using ECMWF Interim Re-Analysis (ERA-Interim) for period 1979–2012. Because mobility BSH through year, EOF analysis is applied to level pressure (SLP) field order investigate principal patterns variability. In each season, three leading modes explain nearly 90% total variance reflect a strengthened or...
Abstract. Nucleation and condensation associated with biogenic volatile organic compounds (BVOCs) are important aerosol formation pathways, yet their contribution to the upper-tropospheric aerosols remains inconclusive, hindering understanding of climate effects. Here, we develop new schemes describing these processes in WRF-Chem model investigate impact on abundance cloud nuclei (CCN) upper troposphere (UT) over Amazon Basin. We find that significantly increase simulated CCN number...
North China is one of the high-risk areas for destructive and strong earthquakes in mainland has experienced numerous historical earthquakes. An earthquake magnitude MW 5.5 struck Pingyuan County, Dezhou city, Shandong Province, China, on 6 August 2023. This was strongest eastern Craton since 1976 Tangshan earthquake. Since did not produce surface ruptures, seismogenic structure fault responsible still unclear. To reveal subsurface geological near epicenter, this study used high-resolution...
Abstract. The response of surface ozone (O3) concentrations to basin-scale warming and cooling Northern Hemisphere oceans is investigated using the Community Earth System Model (CESM). Idealized, spatially uniform sea temperature (SST) anomalies ±1 °C are individually superimposed onto North Pacific, Atlantic, Indian oceans. Our simulations suggest large seasonal regional variability in O3 SST anomalies, especially boreal summer. responses associated with have similar magnitude but opposite...
Ground-level ozone (O3), harmful to most living things, is produced from both domestic and foreign emissions of anthropogenic precursors. Previous estimates the linkage distant sources rely on sensitivity approach (i.e., modeling change concentrations that result modifying precursor emissions) as well tagging tracking specific O3 precursors emitted one region). Here, for first time, we tag all nitrogen oxides (NOx), carbon monoxide (CO), volatile organic compounds (VOCs)) East Asia...
Abstract Eastern part of China (EPC) has experienced rapid urbanization during the past few decades. Here we investigate impacts urban land expansion over EPC on export Asian pollutants to western Pacific January, April, July, and October 2009 using Weather Research Forecasting model coupled Chemistry (WRF/Chem) a single‐layer canopy scheme. Over urbanizing areas, increases in fraction result linearly enhanced uplift surface primary higher altitudes. We further examine how this local effect...
Squall lines frequently invade the Yangtze–Huaihe River region (YHR), where complex terrain of rivers, lakes, and mountains plays an important role in initiation maintenance convection. The surface heat flux not only varies with conditions, but also changes between day night. Coupled forcing, such diurnal–nocturnal thermodynamic differences shift low-level baroclinity, thus further complicate convective activities. To investigate integrated impact on development squall over including...
