The effects of moisture sources and local parameters on the 18O and 2H contents of precipitation in the west of Iran and the east of Iraq

Tellus: Series B, Chemical and Physical Meteorology, 2020
Iran and Iraq face a water shortage crisis especially in the recent decade. Hence, the regions with high potential water resources are highly important to these countries. Precipitation sampling for 18O and 2H analyses was conducted in 10 stations in the

Water stable isotopes in the Yarlungzangbo headwater region and its vicinity of the southwestern Tibetan Plateau

Tellus: Series B, Chemical and Physical Meteorology, 2016
Various types of water samples across the Yarlungzangbo headwater region and its vicinity of the southwestern Tibetan Plateau were collected in summer 2012 for isotopic analysis to augment our specific understanding of regional hydroclimate. In the upper

Oceanic moisture sources contributing to wintertime Euro-Atlantic blocking [PDF]

Weather and Climate Dynamics, 2021
Although conventionally attributed to dry dynamics, increasing evidence points to a key role of moist dynamics in the formation and maintenance of blocking events. The source of moisture crucial for these processes, however, remains elusive.

Moisture sources for Central America: Identification of moisture sources using a Lagrangian analysis technique

Journal of Geophysical Research: Atmospheres, 2010
We herein present an analysis of the sources of atmospheric moisture for Central America using a Lagrangian technique. The results of backward and forward moisture tracking analysis using the FLEXPART model has enabled the identification of the main sources of moisture that reach Central America, as well as an evaluation of their spatial evolution ...

Evaluating Changes in the Moisture Sources for Tropical Cyclones Precipitation in the North Atlantic That Underwent Extratropical Transition

Geophysical Research Letters, 2023
In this study, we investigated the changes in the origin of moisture for the precipitation associated with tropical cyclones (TCs) after extratropical transition (ET) over the North Atlantic Ocean basin from 1980 to 2018. We analyzed the 24 hr before and

Unravelling the transport of moisture into the Saharan Air Layer using passive tracers and isotopes

Atmospheric Science Letters, 2023
The subtropical free troposphere plays a critical role in the radiative balance of the Earth. However, the complex interactions controlling moisture in this sensitive region and, in particular, the relative importance of long‐range transport compared to ...

Sources of Sahelian‐Sudan moisture: Insights from a moisture‐tracing atmospheric model [PDF]

Journal of Geophysical Research: Atmospheres, 2016
AbstractThe summer rainfall across Sahelian‐Sudan is one of the main sources of water for agriculture, human, and animal needs. However, the rainfall is characterized by large interannual variability, which has attracted extensive scientific efforts to understand it.

Effects of horizontal resolution and air–sea coupling on simulated moisture source for East Asian precipitation in MetUM GA6/GC2 [PDF]

Geoscientific Model Development, 2020
Precipitation over East Asia in six Met Office Unified Model (MetUM) simulations is compared with observation and ERA-Interim reanalysis. These simulations include three different horizontal resolutions, from low and medium to high, and including ...
