Special Issue Information

Dear Colleagues,

Air pollution, originating from anthropogenic activities, such as fossil fuel combustion and natural emissions such as wildfire and wind-blowing dust, has profound impacts on human health and multi-scale weather patterns. Particles suspended in a polluted atmosphere strongly absorb or scatter sunlight, depending on particle composition and their optical properties, and ultimately warm or cool the atmosphere. Those particles with diameters larger than 50 nm can activate into cloud droplets under supersaturated air conditions and significantly modify the evolution of convective clouds and stratiform clouds and their capability to reflect shortwave and longwave radiation and form precipitation. The energy imbalance induced by both aerosol–radiation interactions and aerosol–cloud interactions leads to changes in the local or even regional circulation and boundary layer structure, which can, in turn, affect the dilution of air pollution. Understanding the extent to which air pollution affects meteorological parameters is vital for weather and air quality prediction. Numerical models that couple atmospheric chemistry and weather are a powerful tool to probe into this issue. However, more effort is still needed to improve the model skills in representing the air pollution–weather interactions in conjunction with a wide range of atmospheric observations. This Special Issue aims to publish new research on the modeling of air pollution and its weather effect over local, regional or hemispherical scales. We welcome papers on air pollution modeling, the boundary layer and precipitation modulated by particulate matters and ozone, aerosol–cloud–weather interactions, aerosol effects on tropical storms or typhoons, and the development of new modules or the parameterizations of relevant chemical and microphysical processes.

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. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

The possibilities of micrometeorological resilience in urban contexts immersed in a basin geographical configuration are investigated. For this purpose, time series data with measurements of meteorological variables (temperature, magnitude of wind speed and relative humidity) and atmospheric pollutants (PM2.5, PM10, CO) are analyzed through chaos theory, calculating the coefficient of Lyapunov (λ), the correlation dimension (Dc), the Hurst coefficient (H), the correlation entropy (SK), the fractal dimension (D) and the Lempel–Ziv complexity (LZ). Indicators are built for each measurement period (2010–2013 and 2017–2020), for each locality studied and located at different heights. These indicators, which correspond to the quotient between the entropy resulting from the meteorological variables and that of the pollutants, show sensitivity to height. Another important indicator, for identical measurement conditions, arises from the calculation of the fractal dimensions of the meteorological variables and that of the pollutants, which allows for comparative studies between the two periods. These indicators are conclusive in pointing out that, in a large city with basin geographical characteristics, subjected to an intensive urbanization process, there is no micrometeorological resilience and a great variation occurs in the initial conditions.
