Adjustment Of Precipitation Measurements Using Total Rain Weighing Sensor (Trws) Gauges In The Cryospheric Hydrometeorology Observation (Choice) System Of The Qilian Mountains, Northwest China, Zhao Yanni, Chen Rensheng, Han Chuntan, Wang Lei Apr 2022

Adjustment Of Precipitation Measurements Using Total Rain Weighing Sensor (Trws) Gauges In The Cryospheric Hydrometeorology Observation (Choice) System Of The Qilian Mountains, Northwest China, Zhao Yanni, Chen Rensheng, Han Chuntan, Wang Lei

Journal of Arid Land

Precipitation is one of the most important indicators of climate data, but there are many errors in precipitation measurements due to the influence of climatic conditions, especially those of solid precipitation in alpine mountains and at high latitude areas. The measured amount of precipitation in those areas is frequently less than the actual amount of precipitation. To understand the impact of climatic conditions on precipitation measurements in the mountainous areas of Northwest China and the applicability of different gauges in alpine mountains, we established a cryospheric hydrometeorology observation (CHOICE) system in 2008 in the Qilian Mountains, which consists of six …


Identifying Water Vapor Sources Of Precipitation In Forest And Grassland In The North Slope Of The Tianshan Mountains, Central Asia, Chen Haiyan, Chen Yaning, Li Dalong, Li Weihong, Yang Yuhui Apr 2022

Identifying Water Vapor Sources Of Precipitation In Forest And Grassland In The North Slope Of The Tianshan Mountains, Central Asia, Chen Haiyan, Chen Yaning, Li Dalong, Li Weihong, Yang Yuhui

Journal of Arid Land

Identifying water vapor sources in the natural vegetation of the Tianshan Mountains is of significant importance for obtaining greater knowledge about the water cycle, forecasting water resource changes, and dealing with the adverse effects of climate change. In this study, we identified water vapor sources of precipitation and evaluated their effects on precipitation stable isotopes in the north slope of the Tianshan Mountains, China. By utilizing the temporal and spatial distributions of precipitation stable isotopes in the forest and grassland regions, Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model, and isotope mass balance model, we obtained the following results. (1) The …


Effects Of Climate Change And Land Use/Cover Change On The Volume Of The Qinghai Lake In China, Wang Hongwei, Qi Yuan, Lian Xihong, Zhang Jinlong, Yang Rui, Zhang Meiting Apr 2022

Effects Of Climate Change And Land Use/Cover Change On The Volume Of The Qinghai Lake In China, Wang Hongwei, Qi Yuan, Lian Xihong, Zhang Jinlong, Yang Rui, Zhang Meiting

Journal of Arid Land

Qinghai Lake is the largest saline lake in China. The change in the lake volume is an indicator of the variation in water resources and their response to climate change on the Qinghai-Tibetan Plateau (QTP) in China. The present study quantitatively evaluated the effects of climate change and land use/cover change (LUCC) on the lake volume of the Qinghai Lake in China from 1958 to 2018, which is crucial for water resources management in the Qinghai Lake Basin. To explore the effects of climate change and LUCC on the Qinghai Lake volume, we analyzed the lake level observation data and …


Assessment Of Water Resources In Yarmouk River Basin Using Geospatial Technique During The Period 1980–2020, Noor M Al-Kharabsheh Mar 2022

Assessment Of Water Resources In Yarmouk River Basin Using Geospatial Technique During The Period 1980–2020, Noor M Al-Kharabsheh

Journal of Arid Land

It is common knowledge that Yarmouk River Basin (YRB) is shared between Jordan and Syria. Management of YRB trans-boundary water resources is attracting increasing interest because it is a strategic water resource for the riparian countries. Actually, lack of sharing information regarding hydrological flows and basin's water management between partners' countries makes it difficult to distinguish between natural and man-made factors affecting the water body. Therefore, this study seeks to address and assess the main on-site changes that exert on YRB. Geospatial technique and arithmetic equations were combined to carry out an assessment of the changes on water resources in …
