MCI-Based Analysis of Spatiotemporal Characteristics of Drought in Xinjiang over the Past 60 Years: Postprint

Wu Xiulan
2022-01-26 ChinaXiv: chinaxiv-202201.00116

Using daily meteorological data from 99 meteorological stations in Xinjiang from 1961–2020, the daily Meteorological Drought Composite Index (MCI) sequences for each station were calculated according to the latest revised national standard "Grades of Meteorological Drought". The spatiotemporal varia…

Utilizing 24-hour precipitation forecasts at 36-hour lead time from the ECMWF (European Center for Medium-Range Weather Forecast) and GRAPES-GFS (China Meteorological Administration's GRAPES Global Numerical Prediction Operational System, Global/Regional Assimilation and Prediction System-Global For…

Spatiotemporal Characteristics of Pan Evaporation and Its Influencing Factors in the Loess Plateau Region from 1960 to 2018: Postprint

Zhang Yaozong
2022-01-26 ChinaXiv: chinaxiv-202201.00121

Evaporation constitutes a critical process in the hydrological cycle, and investigating pan evaporation in the Loess Plateau region is of paramount significance for regional water resource utilization and protection. By compiling data on pan evaporation, air temperature, wind speed, precipitation, r…

2021-12-30 ChinaXiv: chinaxiv-202201.00022

This study aimed to elucidate the influence of inflow water on the salinity concentration process of a saline lake and the mass balance of Lake Issyk-Kul, a tectonic saltwater lake in Kyrgyzstan. Based on the survey results and meteorological data from 2012 to 2015, we analyzed the dissolved chemica…

Drought and Flood Characteristics in the Farming-Pastoral Ecotone of Northern China Based on the Standardized Precipitation Index Postprint

CAO Huicong, YAN Dandan, JU Yuelin, CAO Huicong
2021-12-30 ChinaXiv: chinaxiv-202201.00023

The farming-pastoral ecotone of northern China (FPENC) provides an important ecological barrier which restrains the invasion of desert into Northwest China. Studying drought and flood characteristics in the FPENC can provide scientific support and practical basis for the protection of the FPENC. Bas…

Contribution of underlying terrain to sand dunes: evidence from the Qaidam Basin, Northwest China Postprint

LI Jiyan, QU Xin, DONG Zhibao, Yingying Cai, LIU Min, Ren Xiaozong, CUI Xujia, LI Jiyan
2021-12-30 ChinaXiv: chinaxiv-202201.00025

Underlying terrain strongly influences dune formation. However, the impacts of underlying terrain on the dune formation are poorly studied. In the present research, we focused on dunes that formed in the alluvial fans and dry salt flats in the Qaidam Basin, Northwest China. We quantified the dunes' …
