Abstract Drylands are home to more than 38% of the world's population and one most sensitive areas climate change human activities. This review describes recent progress in dryland research. Recent findings indicate that long‐term trend aridity index (AI) is mainly attributable increased greenhouse gas emissions, while anthropogenic aerosols exert small effects but alter its attributions. Atmosphere‐land interactions determine intensity regional response. The largest warming during last 100...
Abstract. The seasonal and spatial variations of vertical distribution optical properties aerosols over China are studied using long-term satellite observations from the Cloud–Aerosol Lidar with Orthogonal Polarization (CALIOP) ground-based lidar Aerosol Robotic Network (AERONET) data. CALIOP products validated measurements at Semi-Arid Climate Environment Observatory Lanzhou University (SACOL). Taklamakan Desert Tibetan Plateau regions exhibit highest depolarization color ratios because...
Abstract. Previous studies have shown that bioaerosols are injected into the atmosphere during dust events. These may affect leeward ecosystems, human health, and agricultural productivity even induce climate change. However, bioaerosol dynamics rarely been investigated along transport pathway of Asian dust, especially in China where events huge areas massive numbers people. Given this situation, Dust-Bioaerosol (DuBi) Campaign was carried out over northern China, effects on amount diversity...
Abstract. The particle mixing state plays a significant yet poorly quantified role in aerosol radiative forcing, especially for the of dust (mineral absorbing) and anthropogenic pollution (black carbon over East Asia. We have investigated absorption enhancement mixed-type aerosols Asia by using Aerosol Robotic Network observations transfer model calculations. exhibit significantly enhanced absorbing ability than corresponding unmixed aerosols, as revealed spectral behavior optical depth,...
Abstract To gain an insight into the characteristics of turbulence in a stable boundary layer over complex terrain Loess Plateau, data from Semi‐Arid Climate and Environment Observatory Lanzhou University are analyzed. We propose method to identify efficiently isolate nonstationary motions series, then we examine (nonstationary refer gusty events on greater scale than local shear‐generated turbulence). The occurrence frequency is found depend mean flow, being more frequent weak wind...
The Atlantic Niño is the primary interannual variability mode in tropical Atlantic, with far-reaching impacts on global climate. A recent study identified two types of Niño, each its maximum warming centered central and eastern equatorial respectively. Through analysis observational data numerical model experiments, we find that have distinct climatic Europe. This because associated a pronounced increase precipitation western while positive anomalies during type are mainly...
Abstract In a stable boundary layer (SBL), turbulence is generally weak and exhibits significant intermittent characteristics. Interactions among motions of different scales complicate its structural evolution, making prediction challenging. This study focuses on two typical processes in the SBL: low‐level jet (LLJ) internal gravity waves (IGWs), investigating how their interactions influence evolution structures. Utilizing full observation network data processing system at Zhongchuan...
This paper reports on the comparison of two latest versions (collections 4 and 5) ice cloud products derived from Moderate Resolution Imaging Spectroradiometer (MODIS) measurements. The differences between bulk optical properties clouds used in collections 5 relevant impact simulating correlation bidirectional reflection functions at MODIS bands centered 0.65 (or 0.86) 2.13 mum are investigated. level-3 (specifically, fraction, thickness, effective particle size this paper) collection...
Abstract The assessment of atmospheric aerosol radiative effects in the Tibetan Plateau (TP) suffers from large uncertainties due to limited understanding physicochemical properties. To quantify optical properties, size distributions, and chemical compositions western TP, an intensive field campaign was carried out at Shiquanhe National Reference Climatological Station July 8 August 2, 2019. Unexpected low single scattering albedo (SSA) 870 nm found for fine aerosols with average value 0.73...
Abstract Accurate quantification of the absorption properties brown carbon (BrC) aerosols is crucial to assess Earth‐atmosphere radiative impacts BrC. However, BrC were often misestimated in field observations, due neglecting contribution dust absorption. This study solved this problem by coupling a method for calculating concentration into traditional model quantifying The results show that was up 16.8% sum and northwestern China. potential significantly higher Asia‐located studies...
Abstract Relative roles of anthropogenic aerosols (AAs) and greenhouse gases (GHGs) in land oceanic monsoon changes during boreal summer over the period 1850–2005 Coupled Model Intercomparison Project Phase 5 (CMIP5) models are explored. It is found that GHG effect dominates rainfall trend region. As a result, precipitation western North Pacific (WNP) region Intertropical Convergence Zone (ITCZ) tropical eastern strengthened through so‐called “richest‐get‐richer” mechanism. Over region, AA...
Abstract Operational cloud seeding has been implemented to alleviate local precipitation shortages in China for over half a century. Here, we present quantitative evidence the effect of AgI on supercooled layer clouds with top temperature −15°C China, as documented first time by combination radar, satellite, and disdrometer observations. A radar signature appeared 18 min after seeding, shortly followed visible glaciated track. The expanded horizontally at rate ∼1.4 ∼0.3 m s −1 before 04:25...
Abstract The formation mechanisms of particulate pollution in Lanzhou, which used to be one the most polluted cities across world, remain unclear even though air Lanzhou has been improved recent decades. Multiple online data during 2019–2020 winter was analyze characteristics and reveal Lanzhou. Organic matter, nitrate, sulfate, ammonium accounted for 35.8%, 16.6%, 12.7%, 10.8%, respectively, PM 2.5 mass. contribution secondary inorganic aerosols decreased from low high levels. Nitrate...
