Special Issue Information

Dear Colleagues,

Mineral dust—a type of abundant aerosol particles on Earth, can interact with other components of the Earth system, such as radiation, and produce a wide range of complex effects on, for instance, atmospheric composition, human health, the hydrological cycle, and climate. There have been increasing effort in studying these various interactions from modeling, laboratory, and field experiments. To improve our understanding of the impact of mineral dust on the Earth system, substantial efforts are needed in both observations and modeling. This Special Issue invites contributions that address mineral dust emissions, chemical, physical, and optical properties, and transport and removal, dust impact on atmospheric chemistry and air quality, cloud condensation nuclei (CCN) and ice nuclei (IN) properties of mineral dust, as well as interactions of mineral dust with radiation, clouds, precipitation.

We invite submissions of novel, original investigation and review papers that have important scientific and policy implications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Climate is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract: A 15-year (1997–2011) climatology of dust events at the NASA DFRC in Lancaster, California, USA, was performed to evaluate how the extratropical systems were associated with dust storms over this region. For this study, we collected meteorological data for Edwards Air Force Base (EAFB) in Lancaster, California, which is very close to NASA DFRC, from wunderground.com, National Centers for Environmental Prediction (NCEP)/North American Regional Reanalysis (NARR), NCEP/Hydro-meteorological Prediction Center/National Weather Service (NWS), and Unisys analyses. We find that the dust events were associated with the development of a deep convective boundary layer, turbulence kinetic energy (TKE) ≥3 J/kg, a deep unstable lapse rate layer, a wind speed above the frictional threshold wind speed necessary to ablate dust from the surface (≥7.3 m/s), a presence of a cold trough above the deep planetary boundary layer (PBL), a strong cyclonic jet, an influx of vertical sensible heat from the surrounding area, and a low volumetric soil moisture fraction <0.3. The annual mean number of dust events, their mean duration, and the unit duration per number of event for each visibility range, when binned as <11.2 km, <8 km, <4.8 km, <1.6 km, and <1 km were calculated. The visibility range values were positively correlated with the annual mean number of dust events, duration of dust events, and the ratio of duration of dust events. The percentage of the dust events by season shows that most of the dust events occurred in autumn (44.7%), followed by spring (38.3%), and equally in summer and winter with these seasons each accounting for 8.5% of events. This study also shows that the summer had the highest percentage (10%) of the lowest visibility condition (<1 km) followed by autumn (2%). Neither of the other two seasons—winter and spring—experienced such a low visibility condition during the entire dust events over 15 years. Winter had the highest visibility (<11.2 km) percentage, which was 67% followed by spring (55%). Wind speed increasing to a value within the range of 3.6–11 m/s was typically associated with the dust events. Full article
