2A motion correction on direct estimations of air-sea fluxes from a buoy显示文摘A flux system deployed on a moored buoy has been described,which is capable of directly estimating the airsea fluxes after removing the contamination in the signal due to buoy motion.A triple loop fitting method has been demonstrated for determining the three angular offsets between measurement axes of the sonic anemometer and motion pack.The data collected in an experiment in the Northern Huanghai Sea is used to correct the three sonic anemometer measurements of turbulent wind for buoy motion.The effective removal of wave-scale motion from the spectra and cospectra are demonstrated.Estimates of along-wind momentum flux,sensible heat flux and latent heat flux calculated by the eddy correlation method based on data obtained by sonic anemometer 81000V are shown to be in the same trend and scale with those determined by the bulk aerodynamic method after motion correction.The motion correction not only greatly improve the estimation of the momentum flux but also has a great impact on the calculated sensible heat flux.HUANG Yansong SONG Jinbao FAN Conghui 2013Acta Oceanologica Sinica2013,32,3:2
3On the parameterization of drag coefficient over sea surface显示文摘Six parameterization schemes of roughness or drag coefficient are evaluated on the basis of the data from six experiments. They present great consistency with measurement when friction velocity u*<0.5 m/s (approximately corresponding to 10 m wind speed U10 <12 m/s) and large deviation from measurement when u*≥0.5 m/s (approximately U10≥12 m/s). In order to improve the deviation, a new parameterization of drag coefficient is derived on the basis of the similarity theory, Charnock relationship and Toba 3/2 power law. Wave steepness and wind-sea Reynolds number are considered in the new parameterization. Then it is tested on the basis of the measurements and shows significant improvement when u*≥0.5 m/s. Its standard errors are much smaller than the ones of the other six parameterizations. However, the new parameterization still needs more tests especially for high winds.WANG Juanjuan SONG Jinbao HUANG Yansong FAN Conghui 2013Acta Oceanologica Sinica2013,32,5:2
4Air-sea carbon-dioxide flux estimated by eddy covariance method from a buoy observation显示文摘Precise measurements of the CO2 gas transfer across the air-sea interface provide a better understanding of the global carbon cycle.The air-sea CO2 fluxes are obtained by the eddy covariance method and the bulk method from a buoy observation in the northern Huanghai sea.The effects of buoy motion on flux calculated by the eddy covariance method are demonstrated.The research shows that a motion correction can improve the correlation coefficient between the CO2 fluxes estimated from two different levels.Without the CO2-H2 O cross-correlation correction which is termed as PKT correction,the air-sea CO2 fluxes estimated by eddy covariance method using the motion corrected data are nearly an order of magnitude larger than those estimated by the bulk method.After the CO2-H2 O cross-correlation correction,some eddy covariance CO2 fluxes indeed become closer to the bulk CO2 flux,whereas some are overcorrected which are in response to small water vapor flux.HUANG Yansong SONG Jinbao WANG Juanjuan FAN Conghui 2012Acta Oceanologica Sinica2012,31,6:1
5A review of transportation carbon emissions research using bibliometric analyses显示文摘The transportation sector is one of the major sources of global carbon emissions.In this study,a bibliometric analysis was conducted using CiteSpace and VOSviewer for articles published in the field of transportation carbon emissions(TCEs)between 1997 and 2023.From this analysis,our research shows that:(a)the number of articles on TCEs has grown rapidly since 2010;(b)China,the United States,and the United Kingdom are important research forces,with the Helmholtz Association of German having the highest number of publications;(c)Transportation Research Part D:Transport and Environment is the most cited journal in this field;(d)the current research hotspots mainly focus on theory and methodological approaches,low-carbon travel,green supply chain management,and carbon emission drivers;(e)while,scenario analysis,data envelopment analysis,and vehicle routing problem are popular keywords that have been used in the research field of TCEs in recent years.Finally,using current research trends,our study also proposes a series of future research endeavors for the field of TCEs.Jianqiang Fan Xiaosha Meng Jiaxin Tian Conghui Xing Chao Wang Jacob Wood 2023Journal of Traffic and Transportation Engineering(English Edition)2023,10,5:0
6Water promoted structural evolution of Ag nanocatalysts supported on alumina显示文摘Water is often involved in many catalytic processes,which can strongly affect structural evolution of catalysts during pretreatments and catalytic reactions.In this work,we demonstrate a promotional effect of H_(2)O on both oxidative dispersion and spontaneous aggregation of Ag nanocatalysts supported on alumina.Ag nanoparticles supported onγ-Al_(2)O_(3) and Ag nanowires on Al_(2)O_(3)(0001)can be dispersed into nanoclusters via annealing in O_(2)above 300℃,which is accelerated by introduction of H_(2)O into the oxidative atmosphere.Furthermore,the formed highly dispersed Ag nanoclusters are subject to spontaneous aggregation in humid atmosphere at room temperature.Ex situ and in situ characterizations in both powder and model catalysts suggest that formation of abundant surface hydroxyls and/or water adlayer on the Al_(2)O_(3) surface in the H_(2)O-containing atmosphere facilitates the surface migration of Ag species,thus promoting both dispersion and aggregation processes.The aggregation of the supported Ag nanostructures induced by the humid oxidative atmosphere enhances CO oxidation but inhibits selective catalytic reduction of NO with C_(3)H_(6).This work illustrates the critical role of H_(2)O in structure and catalytic performance of metal nanocatalysts,which can be widely present in heterogeneous catalysis.Conghui Liu Rongtan Li Fei Wang Kun Li Yamei Fan Rentao Mu Qiang Fu 2023Nano Research2023,16,7:0
