The long-term trends of the total column ozone (TCO) over Tibetan Plateau (TP) and factors responsible for are analysed in this study using various observations a chemistry–climate model (CCM). results indicate that low (TOL) TP during winter spring is deepening recent decade, which opposite to recovery signal annual mean TCO after mid-1990s. TOL intensity increasing at rate 1.4 DU/decade area extending with 50,000 km2/decade period 1979–2009. enhanced transport ozone-poor air into...
Climatic fingerprint of Heinrich (H) events was characterized by widespread megadroughts over the Asian summer monsoon (ASM) region accompanied systemic weakening ASM. However, recent studies hydroclimate proxies suggest huge spatial discrepancies in precipitation ASM during some H events, increased Yangtze River Valley contrasting with prevalent across whole region. The mechanism responsible for and relationship between local intensity remain elusive. In this study, we investigate response...
The ecological responses of vegetation to climatic variables along a spatial gradient can be used as guidelines for chronic ecosystem response predictions under global climate change. aboveground net primary productivity (ANPP) factors on the Three-river Headwaters (TRH) region were assessed major types at herbage developmental stages using geographical detectors model, Normalized Difference Vegetation Index from remote sensing images, and precipitation air temperature datasets 2000 2019....
Abstract Accurate precipitation estimation is significant since it matters to everyone on social and economic activities of great importance monitor forecast disasters. The traditional method utilizes an exponential relation between radar reflectivity factors called Z-R relationship which has a low accuracy in estimation. With the rapid development computing power cloud computing, recent researches show that artificial intelligence promising approach, especially deep learning approaches...
In this paper, we intensively collected atmospheric particulate matter (PM) with different diameters (size ranges: <0.49, 0.49–0.95, 0.95–1.5, 1.5–3.0, 3.0–7.2, and >7.2 μm) in Lhasa during the monsoon non-monsoon seasons. The results clearly showed that concentrations of PM, organic carbon (OC), elemental (EC), water-soluble (WSOC) season were much higher than season. During season, a bimodal size distribution OC WSOC, which at <0.49 μm μm, respectively, unimodal for EC observed....
Complex steerable pyramid (CSP) performs well when applied to magnify subtle motions of structures for observing the dynamic characteristics facilities. However, impact types and parameters CSP filters upon performance phase-based optical flow (PBOF) in measuring motion has not been systematically studied. The purpose this study is comprehensively evaluate different filter (Octave, HalfOctave, SmoothHalfOctave, QuarterOctave) on PBOF parameters. Firstly, by simulated translational motion,...
Abstract The East Asian summer monsoon (EASM) plays a crucial role for ecosystems and societies in Asia past, present, future. However, substantial uncertainties remain regarding EASM variability on interdecadal to multidecadal timescales because of the short length instrumental data Asia. This study extended circulation index modern meteorological studies paleoclimate over past half‐millennium (1470–1998 CE) reconcile understanding studies. is reconstructed based common signal from three...
The measurement error of differential reflectivity (ZDR), especially systematic ZDR bias, is a fundamental issue for the application polarimetric radar data. Several calibration methods have been proposed and applied to correct bias. However, recent studies shown that bias time-dependent can be significantly different on two adjacent days. This means frequent monitoring necessary, which difficult achieve with existing methods. As sensitivity has gradually enhanced, large amounts online solar...
There are a large number of tunnels built in permafrost regions every year China. When investigating the road that have been operation cold regions, it was found most these various freezing damages. Therefore, design, construction, operation, and maintenance there still many technical problems need to be solved urgently. Among them, heat preservation, anti-freezing, anti-drainage key determine whether affected by damage. The project based on completed highway Inner Mongolia. Given series...
Abstract Volcanic eruptions have been the most dominant natural forcing of climate change over past millennium, affecting temperature at multiple timescales. However, how volcanic affect regional variability on decadal timescale remains unclear. We analyzed bidecadal effects in mid‐fifteenth century two representative regions (the Tibetan plateau [TP] and Arctic) Northern Hemisphere by combining proxy reconstructions, model ensemble simulations, sensitive experiments. The results show that...
A high performance liquid chromatography( HPLC) method was established for the fast,and precise determination of ten nucleosides in Fritillariae Cirrhosae Bulbus and its counterfeits. Then multivariate statistical analyses,such as clustering analysis,principal component analysis( PCA),and Fisher' s linear discriminant LDA),were conducted to establish a function model an integrated analysis. The results indicated that data acquisition time single sample shortened within 16 min by HPLC method....
Abstract. Aim to striping noise brought by non-uniform response of remote sensing TDI CCD, a novel de-striping method based on statistical features image histogram is put forward. By analysing the distribution histograms,the centroid selected be an eigenvalue representing uniformity ground objects,histogrammic whole and each pixels are calculated first,the differences between them regard as rough correction coefficients, then in order avoid sensitivity caused single parameter considering...
Global climate change has been evident in many places worldwide. This study provides a better understanding of the variability and changes frequency, intensity, duration temperature, precipitation, extremes Extensive Hexi Region, based on meteorological data from 26 stations. The analysis average, maximum, minimum temperatures revealed that statistically significant warming occurred 1960 to 2011. All temperature displayed trends consistent with warming, exception coldest-night (TNn)...

With the rapid development and construction of large-scale wind power bases under “Carbon Peaking Carbon Neutrality Goals” target, traditional energy resource assessment methods typically rely on a limited amount mast data, providing only analysis results. These are incapable capturing spatiotemporal distribution resources throughout entire base, thus failing to meet requirements bases. In this study, mesoscale WRF (The Weather Research Forecasting Model) was employed for simulation in large...
