The Large-Scale Atmospheric Circulation: Confronting Model Biases and Uncovering Mechanisms
Persistent biases in forecast and climate prediction systems hinder our ability to model circulation changes, both in seasonal forecasting and in climate projections.
SPARC Dynvar has established a set of diagnostics (DynVarMIP, endorsed by CMIP6) to enable a mechanistic approach to confront model biases and understand the underlying causes behind circulation changes.
This workshop is an action to launch this effort and reinforce connections between the modeling centers involved in DynVarMIP and the wider research community. As atmospheric reanalyses provide a vital connection between models and the real Earth, we will meet jointly with a subset of the SPARC Reanalysis Intercomparison Project (S-RIP) focused on the Brewer-Dobson Circulation and the Stratospheric-Tropospheric Coupling.
Presentations are called for analysis of seasonal prediction, CMIP, and idealized models on:
- The origin and consequences of systematic models biases in the context of atmospheric dynamics; with a focus on: tropical – extratropical connections, storm tracks, polar vortex and sea ice variability.
- The role of atmospheric dynamics in shaping the climate response to anthropogenic forcing (e.g. global warming, ozone depletion).
- How dynamical processes contribute to uncertainty in climate prediction at seasonal and decadal time scales.
The workshop will provide a forum for:
- Discussion on how best analyze the CMIP6 diagnostics that will be available via DynVarMIP, which targets the DECK experiments (AMIP, abrupt4xCO2 and 1pctCO2), the CMIP6 historical and the ScenarioMIP RCP8.5 experiments, as well as selected experiments within VolMIP, AeroChemMIP, and HiResMIP, where there is natural overlap in scientific interest.
- Explore the possibility of coordinated idealized experiments on dynamical processes
Invited Speakers and Discussion Leaders will introduce presentation topics and stir discussion.
DynVar is a working group of the Stratosphere-troposphere Processes and their Role in Climate (SPARC) Project.
SPARC is a core project of the World Climate Research Program (WCRP).
We thank the Finnish Meteorological Institute for hosting the workshop and anticipate that limited funding will be available to support the attendance of early career scientists.
DynVar Conveners: Ed Gerber, Alexey Karpechko and Elisa Manzini
We would like to bring to your attention a SPARC workshop on "Stratospheric Change and its Role in Climate Prediction (SHARP)" to be held from 16-19 February 2016 in Berlin, Germany.
The SPARC-SHARP workshop aims at addressing relevant issues of stratospheric change, the interaction between atmospheric chemistry and climate change, and the implications for climate and weather in observations and model studies.
The workshop will be organized around four major topics:
- How is the Brewer-Dobson circulation affected by climate change, and which processes are relevant?
- How is the evolution of stratospheric ozone affected by climate change, and how strong is the feedback?
- How is stratospheric water vapour affected by climate change, and which processes are responsible?
- How is the coupling between the stratosphere and troposphere affected by climate change, and how strong is the feedback on climate and weather?
More detailed information on the scientific program, abstract submission, and registration check the official workshop website: http://www.geo.fu-berlin.de/en/met/sharp/news/1st-Announcement-on-SPARC-Workshop.html.
We look forward to welcoming you in Berlin!

We would like to announce a SPARC regional workshop on "Chemical and Physical Processes in the Climate System". The workshop will be held at NCAR in Boulder, CO from Nov 9-10 (directly followed by the SPARC SSG meeting on Nov 10-13).
The purpose of this workshop is to highlight SPARC-related science themes in the Colorado front-range region, and to promote interaction among a broad scale of local and international researchers. The local workshop will focus on 3 SPARC scientific themes:
1) Atmospheric Dynamics and Predictability
2) Chemistry and Climate
3) Long-term records for Climate Understanding
Abstracts are due on Oct. 2nd, and registration is due on Oct. 9th. Early career scientists are especially encouraged to participate.
The website is: https://www2.acom.ucar.edu/sparc.
Hope to see you there!
Find the SPARC bulletin 9/2015 that is sent by email every two months.
Registration deadline extended to 16 September 2015
The CLIVAR Research Focus on Decadal Climate Variability and Predictability (DCVP) is organising a workshop on this theme at the International Centre for Theoretical Physics (ICTP) in Trieste, Italy on 16-20 November 2015. An outline agenda is available on the workshop website, based on the confirmed speakers so far.
The registration has been extended to 16th September there have been funds from the PAGES Project awarded recently to support the participation of scientists from the paleoscience community.
The agenda (oral and poster) will be updated later in September, once the submitted abstracts have been reviewed.
