The “wind of 120days” and dust storm activity over the Sistan Basin
Atmospheric Research, 2014Mesoscale features play a critical role in creating the strong “wind of 120 days” common in eastern Iran and western Afghanistan. The Weather Research and Forecasting with Chemistry (WRF/Chem) model is used with the available observations to investigate the “wind of 120 days”, dust storm activity over the Sistan Basin, and major sources of dust ...

Are dust storm activities in North China related to Arctic ice–snow cover?
Global and Planetary Change, 2006The generation and development of dust storms are controlled by land surface conditions and atmospheric circulations. The latter, in turn, is influenced by the global ice-snow cover. In this study, we examine the relationship between the characteristics of dust storm activities in north China and the changes of global climate patterns.

Geomorphology, 2021
Abstract Improvement in the current knowledge regarding the provenance of loess deposits could clarify complex depositional processes, as well as provide new insights into the paleo-dust storm history in dust source areas. In this study, a comprehensive analysis of the size-differentiated geochemical compositions and zircon U Pb ages of the examined ...

Abstract The Rover Environmental Monitoring Station (REMS) instrument in the Mars Science Laboratory (MSL) mission has collected atmospheric data from Gale crater for more than three Martian years. These data correspond to a path travelled by the Curiosity rover of 18 km in length with differences in altitude of 400 m through a variety of terrains in

Journal of Geophysical Research: Planets, 2020
Gravity wave activity in the lower and middle atmosphere of Mars during the global dust storm of 2018 has been studied for the first time using a high-resolution (gravity wave resolving) general circulation model. Dust storm simulations were compared with those utilizing the climatological distribution of dust in the absence of storms.

Radio Emissions from Electrical Activity in Martian Dust Storms
2020<p>Dust storms on Mars are predicted to be capable of producing electrostatic fields and discharges, even larger than those in dust storms on Earth.&#160; There are three key elements in the characterization of Martian electrostatic discharges: dependence on Martian environmental conditions, event rate, and the strength ...

Dust Storm Influence on Gravity Wave Activity in the Nightside Thermosphere of Mars
Journal of Geophysical Research: PlanetsGravity waves in the thermosphere of Mars are complex and variable phenomena capable of causing significant changes to processes in the upper atmosphere of Mars, which can affect atmospheric escape. The objective of this study is to determine how both dust storm activity and variation in Local Solar Time (LST) affect thermospheric gravity wave activity.

A 10,000 year record of dune activity, dust storms, and severe drought in the central Great Plains
Geology, 2007Dune fi elds and loess deposits of the Great Plains of North America contain stratigraphic records of eolian activity that can be used to extend the short observational record of drought. We present a 10,000 yr reconstruction of dune activity and dust production in the central Great Plains region, based on 95 optically stimulated luminescence ages. The

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
The study focused on the annual dust storm time series of past 36 years in Siziwang County, China. Based on the MHF wavelet method, the temporal-frequency multi-time scale variations and jumping features of dust storm days was analyzed. Then, reveal the periods and turning points of dust storm series in different time-scale and forecast dust storm ...

On the importance of Mongolian cyclones to East Asian dust storm activities
Desert-dust aerosols affect the climate, human health, and socio-ecomomic activities. In East Asia, the passage of Mongolian cyclones induce dust-emitting winds in the Gobi Desert. While cyclones are known as driver of dust outbreaks, the relative contribution of Mongolian cyclones to the total East Asian dust emission amount and the dust aerosol ...Feifei Mu, Stephanie Fiedler
