Abstract Many works suggest that the intensity of extreme precipitation might be changing under background global warming. Because importance in Yellow–Huaihe and Yangtze–Huaihe River basins China to compare spatial difference, generalized Pareto distribution (GPD) function is used fit daily series these an estimate presented. At same time, its long-term trends are estimated for period between 1951 2004 by using a linear model (GLM), which based on GPD. High quality data from 215 observation...
To meet the growing demand for food, land is being managed to be more productive using agricultural intensification practices, such as use of irrigation. Understanding specific environmental impacts irrigation a critical part it sustainable way provide food security. However, our knowledge effects on climate still limited daytime effects. This issue define warming related greenhouse gases (GHGs). study shows that led an increasing temperature (0.002 °C year−1) by enhancing nighttime (0.009...
The East Asian summer monsoon (EASM) shows notable change during the after El Niño peak. This "delayed" response, however, is variable and difficult to predict. Here, we revisit this issue by separating decays into early transition late transition. In an transition, central-to-eastern Pacific evolves a La Niña condition, with positive rainfall anomaly occurring over most parts of eastern China. contrast, in sea surface temperature (SST) remains neutral or slightly above normal;...
Abstract After each of the 1963 Agung, 1982 El Chichón, and 1991 Pinatubo eruptions, an Niño was observed. The increased likelihood after a tropical eruption has also been found in long-term reconstructed proxy data. Through examining simulations over last millennium by 11 different models, we show that volcano can robustly excite western-to-central equatorial Pacific (WCEP) westerly anomaly at 850 hPa eight out models; such is favorable for development. Under volcanic forcing, there are...
Abstract Current understanding of volcanic effects on El Niño–Southern Oscillation in terms eruption type and initial ocean condition (IOC) remains elusive. We use last‐millennium proxy reconstructions to show how impacts depend IOC. When the IOC is not a strong Niño, it likely that an Niño will mature second winter following 79% ( p < 0.01) Northern Hemispheric eruptions first 81% tropical 69% Southern eruptions. For Niño‐IOC, no significant occur after any eruption. The need be large...
Abstract Paleoclimate evidence suggests that tropical volcanic eruptions could increase the likelihood of El Niño occurrence. Previous numerical model studies with zonally uniform aerosol forcing suggested roles land cooling‐induced monsoon suppression and ocean air‐sea interaction in triggering an following eruption. Here, we perform targeted sensitivity experiments by confining over or only fully coupled Community Earth System Model to assess relative these cooling. Our results indicate...
Abstract We analyzed global surface air temperature (SAT) responses to five major tropical volcanic eruptions from 1870 2005 using outputs 97 historical and 58 Atmospheric Model Intercomparison Project (AMIP) runs that participated in phase 5 of the Coupled (CMIP5). In observations, there was a 3-yr cooling trend after eruption due reduced shortwave radiation, 0.1-K average global-mean SAT recovery, consisting El Niño–like warming Eurasian warming, occurred first posteruption boreal winter....
The global land cover has been changed in the last hundreds of years due to human activity.Land change(LCC) affects climate through surface energy and moisture budgets.The purpose this study is understand climatic effects these physical processes by numerical simulation.We used an AGCM+SSiB model simulate sensitivity changes change.The studying area Eurasia.Equilibrium state simulations were conducted summer winter using estimated for 1700,1800,1900,1950 1990.Each simulation experiment run...
Pacific decadal variability (PDV), low-frequency changes in sea surface temperatures (SSTs), significantly impacts global climate. However, disentangling anthropogenic effects upon PDV is challenging since both vary on similar time scales. Using single-forcing climate model large ensembles, we find that forcing primarily drives a spatially-varying pattern of mean-state change North SST project onto leading patterns, principally the Decadal Oscillation (PDO) and Gyre (NPGO). In fact, when...
为研究黑臭河道沉积物资源化利用方式，评估沉积物资源化以后对营养盐去除效果和研究其去除机制，以北京市某黑臭河道沉积物（S）为供试样品，对其进行氧化并负载金属离子改性，最终得到氧化-载钠改性沉积物（MS）.选取S和MS两种材料，评估其对氮和磷的去除效果，通过采用动力学、热力学等手段，进一步阐明改性材料对氮、磷去除机制.结果表明，在环境温度为35℃，固液比1：50（g：ml）的条件下，经氧化-载钠联合改性材料对氮（初始浓度20 mg/L）的去除效果均达到90%以上，其中对磷（初始浓度10 mg/L）的去除率最高可达98%；准二级动力学模型能更好的描述改性材料的吸附动力学行为（R<sup>2</sup>>0.93），且动力学和吸附等温分析结果显示，Langmuir模型可以更好地描述两种材料的吸附等温线，改性材料对氮和磷的最大吸附量分别达到0.891和0.474...
