Inclusion of mineral dust radiative effects could lead to a significant improvement in the radiation balance numerical weather prediction models with subsequent improvements forecast itself. In this study have been fully incorporated into regional atmospheric model. Dust affects fluxes at surface and top atmosphere temperature profiles every model time step when module is processed. These changes influence dynamics, moisture physics, near‐surface conditions. Furthermore, emission modified by...
Abstract. Dust storms and associated mineral aerosol transport are driven primarily by meso- synoptic-scale atmospheric processes. It is therefore essential that the dust process background conditions drive emissions represented with sufficiently well-resolved spatial temporal features. The effects of airborne interactions environment determine composition particles. fractions various minerals in determined arid soils; therefore, a high-resolution specification physical properties sources...
Abstract. Dust particles from high latitudes have a potentially large local, regional, and global significance to climate the environment as short-lived forcers, air pollutants, nutrient sources. Identifying locations of local dust sources their emission, transport, deposition processes is important for understanding multiple impacts high-latitude (HLD) on Earth's systems. Here, we identify, describe, quantify source intensity (SI) values, which show potential soil surfaces emission scaled...
On 5 July 2011, a massive dust storm struck Phoenix, Arizona (USA), raising concerns for increased cases of valley fever (coccidioidomycosis, or, cocci). A quasi-operational experimental airborne forecast system predicted the event and provides model output continuing analysis in collaboration with public health air quality communities. An objective this was to see if signal region could be detected traced – an American haboob. To better understand atmospheric life cycle cocci spores, DREAM...
Abstract. Systematic measurements of dust concentration profiles at a continental scale were recently made possible by the development synergistic retrieval algorithms using combined lidar and sun photometer data establishment robust remote-sensing networks in framework Aerosols, Clouds, Trace gases Research InfraStructure Network (ACTRIS)/European Aerosol Lidar (EARLINET). We present methodology for these capabilities as tool examining performance transport models. The includes...
Abstract. A dust storm of fearful proportions hit Phoenix in the early evening hours 5 July 2011. This storm, an American haboob, was predicted advance because numerical, land–atmosphere modeling, computing power and remote sensing events have improved greatly over past decade. High-resolution numerical models are required for accurate simulation small scales haboob process, with high velocity surface winds produced by strong convection severe downbursts. Dust productive areas this region...
Abstract. In the framework of World Meteorological Organisation's Sand and Dust Storm Warning Advisory Assessment System, we evaluated predictions five state-of-the-art dust forecast models during an intense Saharan outbreak affecting western northern Europe in April 2011. We assessed capacity to predict evolution cloud with lead times up 72 h using observations aerosol optical depth (AOD) from AErosol RObotic NETwork (AERONET) Moderate Resolution Imaging Spectroradiometer (MODIS) surface...
Abstract. Dust aerosols are very efficient ice nuclei, important for heterogeneous cloud glaciation even in regions distant from desert sources. A new generation of nucleation parameterizations, including dust as an agent, opens the way towards a more accurate treatment cold formation atmospheric models. Using such we have developed regional dust-atmospheric modelling system capable predicting, real time, dust-induced nucleation. We executed model with added component over Mediterranean...
Abstract Ice particles in high-altitude cold clouds can obstruct aircraft functioning. Over the last 20 years, there have been more than 150 recorded cases with engine power-loss and damage caused by tiny cloud ice crystals, which are difficult to detect radars . Herein, we examine two accidents for icing linked convective weather conditions has officially reported as most likely reason catastrophic consequences. We analyze whether desert mineral dust, known be very efficient nuclei present...
Icelandic topsoil sediments, as confirmed by numerous scientific studies, represent the largest and most important European source of mineral dust. Strong winds, connected with intensive cyclonic circulation in North Atlantic, induce intense emissions dust from local sources all year carry away these fine aerosol particles for thousands kilometers. Various impacts airborne on air quality, human health, transportation, climate marine ecosystems motivated us to design a fully dynamic coupled...
On 2 June 2014, at about 13 UTC, a dust storm arrived in Tehran as severe hazard that caused injures, deaths, failures power supply, and traffic disruption. Such an extreme event is not considered common for the area, which has raised question of storm’s origin need increasing citizens’ preparedness during such events. The analysis observational data numerical simulations using coupled dust-atmospheric models showed intensive convective activity occurred over south southwest Tehran, produced...
Abstract. Dust particles emitted from high latitudes (≥ 50° N and ≥ 40° S, including Arctic as a subregion 60° N), have potentially large local, regional, global significance to climate environment short-lived forcers, air pollutants nutrient sources. To understand the multiple impacts of High Latitude (HLD) on Earth systems, it is foremost identify geographic locations characteristics local dust Here, we identify, describe, quantify Source Intensity (SI) values using Global Sand Storms Base...
