Special Issue Information
Dear Colleagues,
Understanding and predicting the dynamic of the stable boundary layer is of paramount importance for the PBL community.
The stable boundary layer is an intricate pattern of turbulent and non-turbulent motions on different scales. The balance of the turbulent kinetic energy production and buoyancy destruction drive the transition between turbulent and non-turbulent states in which a wide range of phenomena, known as the submeso motions, interact, giving rise to intermittent turbulent episodes. In cases of very stable stratification, pollutants are trapped near the ground, strongly affecting air quality. Further, the very stable boundary layer is always associated with low-wind speed episodes, which are important for wind power assessment. Unfortunately, our understanding is still limited, and atmospheric and dispersion models poorly perform in the VSBL because submeso motions are not correctly resolved. The vertical decoupling of the boundary layer complicates the parameterization of the turbulent fluxes with the Monin–Obukhov similarity theory.
This Special Issue aims to address the following topics: Submeso–turbulence interaction, the transition between a weakly and very stable boundary layer, the role of radiation and clouds in triggering the VSBL, and the original parameterization of the VSBL dynamics.

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.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 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.
