Abstract To develop a finescale dataset for the purpose of analyzing historical climatic change over Tibet Plateau (TP), high-resolution regional climate simulation 1979–2011 was conducted using Weather Research and Forecasting (WRF) Model driven by ERA-Interim (ERA-Int). This work evaluates (30 km) WRF in terms annual variation, spatial structure, 33-yr temporal trends surface air temperature (Tair) precipitation (Prec) TP, with reference to station observations. Another focus is on...
Desertification in the Tibetan Plateau (TP) has drawn increasing attention recent decades. It been postulated as a consequence of climate aridity due to observed warming. This study quantifies changes TP and attributes different climatic factors. Using ratio precipitation potential evapotranspiration (P/PET) an index, we used meteorological records at 83 stations calculate PET using Penman–Monteith algorithm ratio. Spatial temporal P/PET 1979–2011 were analyzed. Results show that located...
Abstract Available observations below 5000 m altitude suggest that some mountain regions are undergoing accelerated elevation-dependent warming (EDW) in response to global or regional climate change. We address the question of whether EDW exists above altitude, which is elevation much mountainous portion Tibetan Plateau, and headwaters most Asia’s major rivers. analyzed four data sources: situ observations, gridded ERA-Interim reanalysis, Weather Research Forecasting (WRF) model output over...
ABSTRACT Quality of a downscaling depends primarily on the quality driving global climate model ( GCM ). In this study, historical atmospheric conditions simulated by 14 GCMs in CMIP5 are evaluated for applications centred over Tibetan Plateau TP ) with ERA ‐Interim reanalysis as reference. Another NCEP‐DOE is also used to estimate uncertainty associated reanalyses. Performances six frequently variables, involving circulation, air temperature and humidity, terms biases, spatial correlation...
ABSTRACT Past studies on regional climate change over the Tibetan Plateau (TP) have mainly looked at changes in mean climate. This study focuses past and future extreme precipitations, simulated by global models TP. To assess influence of large‐scale forcing dynamic downscaling using Weather Research Forecasting (WRF) model, results for historical period (1980–2005) with ERA‐Interim reanalysis CCSM4 as forcings are evaluated against a gridded observational data set. These inter‐compared...
Abstract To meet the requirement of high-resolution datasets for many applications, a dynamical downscaling approach using regional climate model (the WRF Model) driven by global (CCSM4) has been adopted. This study focuses on projections future moisture flux changes over Tibetan Plateau (TP). First, results historical period (1980–2005) are evaluated precipitation P, evaporation E, and minus P − E against Global Land Data Assimilation System (GLDAS) data. The mechanism is analyzed...
The deposition couplets within the check dams and landslide-dammed reservoirs on Chinese Loess Plateau (CLP) document processes histories of watershed soil erosion, transportation deposition, related to floods, eco-environment land use changes, human activities. Previously, dating was dominantly dependent multiple intercomparisons among specific sediment yields visible couplets, 137 Cs activities distributions erosive rainfall events by meteorological records. However, inter-annual division...
As the scale of parallel machine grows, communication network is playing more important role than ever before. Communication affects not only execution time, but also scalability applications. Parallel interconnection simulator a suitable tool to study large-scale networks. However, simulating packet level on detailed cycle-to-cycle models really challenge work. We implement kernel-based HPPNetSim solve problems. Optimistic PDES mechanism needs huge memory consumption saving simulation...
Abstract Variations and regional differences in land surface processes during the Anthropocene have directly impacted local economic development social stability. Nevertheless, little is known about historical erosion effects human–environment interactions at annual decadal scales on central Chinese Loess Plateau (CLP) over past 200 years, when human activities sediment discharge both reached peaks. Located northcentral hilly–gully southcentral plateau–gully regions, respectively, Jingbian...
