Special Issue Information
Dear Colleagues,
We have seen an enormous increase in the attention paid to isotropic turbulence in recent years. However, research in this field is divided into many different topics, each with its own group of adherents, which leads to a lack of informed consensus. In fact, it could be said that, when considered overall, the subject lacks both focus and direction. Of course, this is not really surprising, given the heterogeneous nature of the community studying it, which ranges from applied scientists and applied mathematicians to theoretical physicists and, more recently, pure mathematicians. Naturally, the topics studied exhibit a similar diversity, and, for this reason, we think that it will be helpful to divide them up into three broad strands. These are as follows:
- Fundamentals (thermodynamic aspects, validity of equations and the continuum limit, Taylor’s dissipation surrogate, Onsager’s conjecture and related physics, limit of infinite Reynolds numbers, Euler and Navier–Stokes equations driven by random inputs, and the relevance of intermittency).
- Phenomenology (conservation of energy, asymptotic behaviour with increasing Reynolds number, Kolmogorov (1941) theory, Onsager’s model and scale invariance of the energy flux, dimensionless dissipation, two-time correlations and temporal spectra, and finite Reynolds number effects).
- Statistical Theory (Eddy viscosity models, renormalized perturbation theories, Eulerian DIA and LET theories, Lagrangian theories, single-time Markovian models, mode elimination and sub-grid models, and renormalization group).
The aim of this Special Issue is to publish papers which can help to identify the most recent advances and what the current challenges are. Thus, we ask for submissions which have both a pedagogical and a review perspective. That is, they should be written to be intelligible to those outside your own subject area, and they should eschew experimental details and mathematical derivations alike, as these may be covered by references to your other published work.

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.
