Special Issue "Precipitation Variability and Change in Africa"
Deadline for manuscript submissions: closed (28 February 2018)
Sub-Saharan Africa is one of the most vulnerable regions to climate change, while, at the same time, several aspects of regional climate dynamics are still poorly understood. Projections of climate change using global circulation models (GCMs) generally agree on a temperature increase of 3 to 4 °C by the end of the 21st century. However, the projections of precipitation patterns, arguably the most important single climate variable in large parts of Africa, differ considerably between models due to model physics, resolution and the parameterization of subgrid-scale (e.g., convective) processes. In particular, differences in the treatment of soil moisture between models seem to play a crucial role. Changes in the onset and decay of the rainy season(s) have been documented, and some models even project a transition from a unimodal rainfall region (characterizing the inner tropics under present-day climate) to a bimodal regime with two dry and two wet seasons. As farming in most regions of sub-Saharan Africa is closely linked to the occurrence and timing of sufficient rainfall, the onset, length, precipitation amount and reliability of the rainy season will have a large effect on crop productivity and harvest.
This Special Issue aims at advancing our current knowledge on African precipitation and its past and future changes. Articles addressing modeling issues, both with GCMs or downscaled regional scenarios, as well as aspects of model physics and parameterization are welcome. As there is a lack of observations in many parts of Africa, analyses of observations or of historical data are especially encouraged. Further, articles on precipitation characteristics, such as timing of dry and wet seasons, rainfall regimes, and their changes are welcome.

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 papers will be 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 1400 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.
