Special Issue Information
Dear Colleagues,
As one of the most radical phenomena in the climate system, sudden stratospheric warming (SSW) mainly occurs in the Northern Hemisphere in midwinter, when the Arctic stratosphere warms by tens of degrees within a week. SSWs and some early find warmings (SFWs) are a period of strong stratosphere-troposphere coupling, and the negative northern annular mode (NAM) signal associated with SSWs and SFWs can propagate downward from the stratosphere to the troposphere, which possibly increases the possibility of the continental cold surge and its predictability on the sub-seasonal to seasonal timescale. One recent example is the persistent continental cold surge in Eurasia and North America following the January 2021 SSW. Due to the possible downward impact of SSWs, their predictability has attracted wide attention in the community in past years. Further, underrepresentation of SSWs is still a common bias for some CMIP5/6 models, which partially contributes to uncertainty in the future projection of SSWs. Divergence still exists in the literature for the projected future change in the frequency, intensity, and possible near-surface impact of SSWs. As some SSWs were observed in the Southern Hemisphere in spring, a possible impact of SSWs in the Southern Hemisphere also rouses wide interest. However, it is still unknown what the (especially the minor) SSW in the Southern Hemisphere will change in the future. Due to those limitations of SSW studies, we are pleased to announce the Special Issue “Observation, Prediction, Simulation and Future Projection of Sudden Stratospheric Warming and Its Impact”.
Manuscripts solicited for this Special Issue are in research areas including, but not limited to, the following topics:
- Observational characteristics of SSWs in both hemispheres in reanalysis and satellite datasets;
- The possible impact of SSWs on regional rainfall (drought and flood), near-surface temperature (cold surge and heat wave), and PM2.5 concentration;
- Case or composite studies of the SSW predictability using sub-seasonal to seasonal (S2S) reforecasts/forecasts;
- The reproducibility of the stratospheric polar vortex and SSWs in some individual models or multiple models from a series of CMIPs, especially the most recent CMIP6;
- Possible changes and future projection of SSW’s impacts.
Other topics related to stratospheric dynamics, physics (especially radiation), and chemistry are also 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 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).
