Abstract. Regional PM2.5 transport is an important cause of atmospheric environment change. However, the variations in regional on a synoptic scale with meteorological drivers have been incomprehensively understood. Therefore, this study targeted at quasi-weekly oscillation (QWO) over central and eastern China (CEC) influence synoptic-scale disturbance East Asian winter monsoon (EAWM) circulation. By constructing data daily flux CEC winters 2015–2019, we utilize extended empirical orthogonal...
Abstract Parameterizations of entrainment and detrainment rates ( ε δ ) are crucial for climate models. Although satellite‐derived estimates available in the literature, there has been a deficiency satellite‐based retrievals . To fill this gap, recently developed approach is applied to satellite observations. The retrieved validated against aircraft observations confirming reliability Results show that global exhibit significant latitudinal variations land‐ocean contrast, but no...
Turbulence kinetic energy (TKE) is widely used to characterize the spatio-temporal changes of atmospheric turbulence. The objective this study investigate near-surface TKE characteristics under different convection regimes classified by ratio buoyancy term (BP) shear (SP) based on sonic anemometer data measured at four boundary layer towers in China with contrasting underlying surfaces. annual average diurnal variations and related variables (BP, SP, friction velocity u∗, wind speed u¯) are...
The climatic characteristics and temperature profiles of freezing rain in China are analyzed based on the observational data at 650 stations from 2000 to 2015. is generally stripe-shape spatial distribution. with over 100 station-hours mainly concentrated southeast areas Southwest high-elevation mountainous Eastern China. There two types profiles, including single-warm-layer profile double-warm-layer profile. area urban similar each other, Central East shares South show rain’s both...
Abstract Massive-flow air samplers are being deployed around the world to collect aerosol samples for analysis of radioactivity as a result nuclear tests and accidents. An wind tunnel capable an 1100 m3 min−1 flow rate was built at Lovelace Respiratory Research Institute (LRRI) test sampling efficiency these samplers. This uses stationary blender enhance mixing, therefore it achieves required uniform distribution speed concentration in section. The section has cross that is 4.3 m × 3.7 m....
NIOSH-certified respirators, including N95 are recommended when engineering and administrative controls do not adequately prevent exposures to airborne nanomaterials. Laboratory evaluations of filtering efficiency using standard test aerosols have been reported in the literature, but there is no information on penetration engineered nanoparticles (1–100 nm) for facepiece respirators (FFR). This project evaluated performance two manufacturers' FFR filters challenged with nanoparticle...
Pump-probe microscopy of melanin in tumors has been proposed to improve diagnosis malignant melanoma, based on the hypothesis that aggressive cancers disaggregate structure. However, measured signals are complex superpositions multiple nonlinear processes, which makes interpretation challenging. Polarization control during measurement and data fitting used decompose into their underlying molecular mechanisms. We then identify mechanisms most susceptible disaggregation derive false-coloring...
When a nebulizer is evaluated by the Andersen Cascade Impactor (ACI), flow rate generally maintained at 28.3 L/min, as recommended manufacturer. However, that patient inhales only around 18 L/min. Because drive of approximately 6–8 nebulized drug mixed with outside air when delivered. Evaluating impactor performance L/min less than ideal because an additional 10 drug, thereby affecting size distribution and dose before inhalation deposition in human lung. In this study we operated ACI 18.0...
The Qinghai-Tibet Plateau is an extremely vulnerable area that sensitive to human activities. In recent years, more and disturbances have been detected in this area. This study analyzed the spatial distribution ecological risks of 7 heavy metals (Cr, Ni, Cu, Zn, As, Cd, Pb) two regions, namely Bailong River Yellow their tributaries (BY region) Gannan Yarlung Zangbo its (YZ Tibet. terms distribution, concentrations seven were higher east lower west BY region. average all exceeded background...
The evolution of the microphysical properties raindrops from Typhoon Mangkhut's outer rainbands as storm made landfall in South China September 2018 was investigated. observations by three two-dimensional video disdrometers deployed central Guangdong Province were analyzed concurrently. It found that radial distribution median volume diameter (D0) and normalized intercept parameter (Nw) varied different stages, smaller than 3.0 mm contributed more 99% total precipitation. Considering...
Both the similar and different effects of freezing drizzle, sleet snow on microphysical properties supercooled fog were analyzed for fourteen events during a comprehensive wire icing, fog, precipitation observation experiment conducted at Enshi radar station (30°17′N, 109°16′E; 1722 m a.s.l.) hilltop in Shibanling, Hubei, China. Liquid is relatively stable form mountainous areas. Short-term (1–3 h) dominant with temperature below 0 °C. The wet scavenging effect drizzle small droplets size...
Research on three types of wire icing evolution mechanism is great significance for ice disaster recognition and prediction. Comprehensive field observations were conducted in the winters 2015/2016 2016/2017 at Lushan Mountain Meteorological Bureau Observatory (elevation 1164.5 m), Jiangxi Province, China, thickness, weather phenomena, meteorological elements, fog spectrum measured. Four cases recorded, which high ice-producing conditions, such as freezing rain, snow supercooled fog,...
This paper proposes an effective gait recognition approach based on the Gait Energy Image (GEI) representation. Synthetic GEI samples are first generated to address problem of lacking training data. Then Gabor phase spectrum which was ignored in previous work is utilized as input feature, and it subsequently embedded into a low dimensional manifold by locality preserving projections perform classification. The proposed evaluated USF HumanID database. Experimental results show that our...
Titanium dioxide (TiO2) is one of the most widely used nanoscale materials to date and could result in human exposures. The main objective this study was perform detailed characterization TiO2 agglomerate particles how these properties influence particle penetration a screen filter. Transmission electron microscope (TEM) photos showed compact agglomerates primary particles. projected area diameter close mobility diameter, where length about 25% larger than diameter. mean aspect ratio...
Abstract With the liberalization of electricity trading market, market participants pay more attention to fair and reasonable distribution relevant costs. However, traditional transmission cost allocation methods based on fixed costs have serious cross-subsidies. In this context, a variety for amortizing from different angles emerged, but these generally some shortcomings, such as excessive calculations. To select optimal method objectively rationally, paper uses entropy weight evaluate four...
The dual land market has greatly encouraged the economy and urban development created far-reaching effects on excessive expropriation finance. Using an analytical framework of structure model, this paper investigates relationship between local finance China's rapid urbanization. Low-cost is main reason why extensive urbanization goes so fast in recent China. Granting farmers complete rights, implementing property tax to consolidate bases, unifying are helpful achieve both social equity use...
