Essential nutritional ions show enrichment (K+, Mg2+) and depletion (NO3−) in runoff water generated by biocrusts covering arid sand dunes under natural rain conditions

open access: yesHydrological Processes, Volume 38, Issue 9, September 2024.
Enrichment of K, Mg, NH4 and SO4 and depletion of Ca and NO3 in runoff water over biocrusts is explained by microorganism involvement. Abstract The role of runoff in providing nutrients to runon loci in deserts was not extensively explored. Here we report 2 years of measurements of the chemical composition of rain and runoff (three events for each year,

Where Dust Comes From: Global Assessment of Dust Source Attributions With AeroCom Models

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 16, 28 August 2024.
Abstract The source of dust in the global atmosphere is an important factor to better understand the role of dust aerosols in the climate system. However, it is a difficult task to attribute the airborne dust over the remote land and ocean regions to their origins since dust from various sources are mixed during long‐range transport.

The Performance of a Scale-Aware Nonlocal PBL Scheme for the Subkilometer Simulation of a Deep CBL over the Taklimakan Desert

open access: yesAdvances in Meteorology, 2018
Although realistic representation of the convective boundary layer (CBL) in the desert region in Northwest China is important for weather forecasts and climate simulations, evaluations of the performance of various planetary boundary layer (PBL) schemes ...

A study on aeolian dust outbreak in East Asia [PDF]

open access: yes, 2004
The impact of aeolian dust on climate has been recognized to be large due to radiative effect. Intergovernmental Panel on Climate Change (IPCC) [2001] also treats the aeolian dust as an important factor of climate change.

Large Asian dust layers continuously reached North America in April 2010 [PDF]

open access: yes, 2011
The NASA space-borne Mie-lidar system CALIPSO/CALIOP revealed that multiple large Asian dust layers with a horizontal scale of 2000–3000 km reached North America, occupying the full troposphere, in April 2010.

Theoretical analysis of the limiting rate of phreatic evaporation for aeolian sandy soil in Taklimakan Desert [PDF]

open access: yes, 2008
Phreatic evaporation is a great lose for shallow groundwater in the Taklimakan Desert. Given soil type and groundwater table, the limiting rate of phreatic evaporation is defined as the maximum of water transferred from groundwater to soil surface per ...
