Special Announcements

Open Call for SPARC SSG Membership
SPARC leadership is composed of experts from around the world who dedicate their time to SPARC's international activities. These include the SPARC Scientific Steering Group (SSG), who serve to guide SPARC's scientific focus. SPARC is now accepting nominations (or self-nominations) for SSG membership to serve from January 2018 - December 2020 (initial three-year term can be extended by two additional years). If you are interested please complete the online form available here. The deadline for nominations is 30 September 2016.

WCRP-SPARC Workshop: Challenges for Climate Science - Synergies between SPARC and the WCRP Grand Challenges

Berlin, Germany, 31 November – 1 December 2016 
Held back-to-back with the annual meeting of the SPARC scientific steering group, this workshop brings together scientists active in Grand Challenge research, in different SPARC activities, and scientists that so far have had fewer links to WCRP. 
The workshop has the following aims: (1) To discuss the state of the science in the areas of Grand Challenges and SPARC themes; (2) To define improved collaborations between SPARC and the Grand Challenges; (3) To discuss the role of SPARC and Grand Challenges in WCRP priorities.
Find more information; registration deadline: 30 September.

Summer School on Atmospheric Composition and Dynamics

Reunion Island, 28 November – 3 December 2016
The Maïdo Observatory Summer School (MOSS) will focus on troposphere‐stratosphere composition and dynamics. The MOSS is intended to further develop understanding of monitoring techniques, processes and changes in the Earth's atmosphere (troposphere and stratosphere) with emphasis on dynamics, long‐term evolution of atmospheric composition, and climate change. The academic activities will be based on courses and training in accordance with SPARC (Stratosphere‐ troposphere Processes And their Role in Climate) activities and with its strategy in terms of capacity development.
The School is scheduled for 6 days of coursework and is open to PhD students and early career researchers in the field of instrumentation and atmospheric sciences.
See the summer school website for further information.

An unexpected disruption of the atmospheric quasi-biennial oscillation.
By S. M. Osprey et al. in Science.

One of the most repeatable phenomena seen in the atmosphere, the quasi-biennial oscillation (QBO) between prevailing eastward and westward wind-jets in the equatorial stratosphere (~16-50 km altitude), was unexpectedly disrupted in February 2016. An unprecedented westward jet formed within the eastward phase in the lower stratosphere and cannot be accounted for by the standard QBO paradigm based on vertical momentum transport. Instead the primary cause was waves transporting momentum from the Northern Hemisphere. Seasonal forecasts did not predict the disruption but analogous QBO disruptions are seen very occasionally in some climate simulations. A return to more typical QBO behavior within the next year is forecast, though the possibility of more frequent occurrences of similar disruptions is projected for a warming climate.
