Characteristics of Hydrogen-Oxygen Isotopes and Water Vapor Sources of Different Waters in the Ili Kashi River Basin

Water, 2022
Abstract This study investigated the hydrogen-oxygen stable isotope characteristics of different water bodies, from the perspectives of elevation, season, and interannual variation, using water samples of atmospheric precipitation, river water, groundwater, and ice–snow meltwater obtained in the Ili Kashi River Basin from July 2018 to June 2021.

The Physical Mechanisms Behind the Change in the Precipitation Recycling Rate in the Mid- and Lower Reaches of the Yangtze River

Frontiers in Physics, 2021
The precipitation recycling rate (PRR) is an important index when trying to understand the physical mechanisms behind the effects of different sources of water vapor on regional precipitation.

G305.8 - 0.2 water vapor source - A young object

The Astronomical Journal, 1991
Observations of water vapor and silicon monoxide masers were conducted in the direction of G305.8−0.2. No SiO maser emission above 7 Jy of flux density was detected. The short-time variability of the H 2 O maser together with the absence of compact radio continuum emission suggests that the excitation energy of the maser could originate from an O7-O9 ...

Sources of water vapor and their effects on water isotopes in precipitation in the Indian monsoon region: a model-based assessment

Scientific Reports, 2023
AbstractClimate records of ratios of stable water isotopes of oxygen (δ18O) are used to reconstruct the past Indian monsoon precipitation. Identifying the sources of water vapor is important in understanding the role of monsoonal circulation in the δ18O values, to aid in monsoon reconstructions.

Modeling insights into deuterium excess as an indicator of water vapor source conditions [PDF]

Journal of Geophysical Research: Atmospheres, 2013
Deuterium excess (d) is interpreted in conventional paleoclimate reconstructions as a tracer of oceanic source region conditions, such as temperature, where precipitation originates. Previous studies have adopted coisotopic approaches (using both δ18O and d) to estimate past changes in both site and oceanic source temperatures for ice core sites using ...

Water vapor sources and their contributions to precipitation change in the Tibetan Plateau

Shui kexue jinzhan
In recent decades，precipitation on the Tibetan Plateau（TP）increased in the north and decreased in the south，leading to greater complexity and uncertainty of the water resources system.

Analysis on the Temporal and Spatial Evolution Characteristics of Water Vapor Transport and Budget over the Source Region of the Three-River

Gaoyuan qixiang, 2022
The Source Region of the Three-River （SRTR） lies in the hinterland of the Qinghai-Xizang （Tibetan） Plateau （QXP） and is one of the sensitive regions to climate change in East Asia.It is of great significance to study the distribution， transport， and ...

Water Vapor Sources of the October 2000 Piedmont Flood

Journal of Hydrometeorology, 2004
Abstract Very intense mesoscale or synoptic-scale rainfall events can occasionally be observed in the Mediterranean region without any deep cyclone developing over the areas affected by precipitation. In these perplexing cases the synoptic situation can superficially look similar to cases in which very little precipitation occurs.
