DynVar Workshop 3: April 2013
Invitation to participate in the
3rd SPARC / Dynamical Variability (DynVar) Workshop
22-24 April 2013, Reading, England, UK
1st SPARC / Stratospheric Network for the Assessment of Predictability (SNAP) Workshop
24-26 April 2013, Reading, England, UK
A joint DynVar/SNAP session will be held on 24 April
The SPARC DynVar Activity will hold its 3rd workshop, 22-24 April 2013, jointly with the 1st SPARC SNAP workshop, 24-26 April 2013, in Reading, England, UK. The first 2 days of the DynVar workshop will consist of presentations (oral and posters) and open discussions including DynVar Research Topics. The 3rd day will be a joint DynVar/SNAP session focused on work on stratospheric predictability common to both initiatives. The last 2 days of the SNAP workshop will focus on the design of a new multi-model experiment on stratospheric predictability on sub-seasonal timescales. Participants are encouraged to attend both events. University of Reading will kindly host both the DynVar and SNAP workshops.
The aims of the SPARC/DynVar Workshop are two-fold, first to provide a forum for:
• discussion of the role of stratospheric dynamics and variability in CMIP5 and SHFP models
• identifying the most critical deficiencies in the representation of the stratosphere in current models. Where and how can models be improved?
• bringing insights from theory and observations to model development and consequently to prediction efforts.
and secod to discuss the future direction of the DynVar Activity. The DynVar Workshop is organized around the DynVar Research Topics.
Keynote speakers: Joan Alexander and Ted Shepherd
Invited speakers: Thomas Birner, Amy Butler, Chiara Cagnazzo, Natalia Calvo, Alexey Karpechko, Thomas Krismer, Scott Osprey, Judith Perlwitz, Thomas Reichler, Tiffany Shaw, and Isla Simpson
We call for submission on (but not limited to) the following research areas:
• Stratospheric dynamical processes (mean, variability and change) and their representation in climate models
• Mechanisms of two-way stratosphere-troposphere coupling
• Influence of stratospheric dynamics on the mean state and variability of the troposphere, ocean, sea ice and carbon fluxes
• Role of stratospheric dynamics in tropospheric climate change and its implications
Single and multi-model analyses of CMIP5 and SHFP simulations are welcome. Expected outcomes of the DynVar workshop will be (1) publications on the status of modeling the stratosphere and stratosphere-troposphere dynamical coupling as benchmarked by the CMIP5 and SHFP simulations, covering the DynVar Research Topics; (2) requirements for advancing stratospheric modeling; (3) input for the implementation plan of DynVar next phase.
The Stratospheric Network for the Assessment of Predictability (SNAP) is a new SPARC initiative to investigate stratospheric predictability and its impact on the skill of medium-range to sub-seasonal forecasts throughout the troposphere and stratosphere. The project will seek to gain insight into stratospheric predictability by the design, execution and analysis of new multi-model stratospheric predictability experiments. The project is funded by the UK Natural Environment Research Council and SPARC and has initial project partners in five weather forecasting centres. The aim of the first SNAP workshop is to design this experiment and to build a network of researchers interested in stratospheric predictability, who will contribute to the analysis of results from the experiments.
We call for participation in the SNAP workshop from:
• Researchers who would like to present recent work on stratospheric predictability and stratosphere-troposphere coupling as a talk or poster to inform development of the network and experiment design
• Researchers with an interest in the SNAP project who would like to contribute to the experimental design and who have an interest in scientific analysis of the pooled output of the experiments.

DynVar Workshop 2 (November 2010)
The SPARC DynVar Activity has held its 2nd workshop in Boulder, Colorado, USA, 3-5 November 2010. The Workshop was kindly hosted by the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory’s (ESRL) Physical Sciences Division in collaboration with the Cooperative Institute for Research in Environmental Sciences (CIRES) at University of Colorado, and was held at NOAA ESRL David Skaggs Research Center.
The outcomes of the workshop are reported on the SPARC Newsletter 36 (Manzini et al, p 19) January 2011.
Background: The SPARC DynVar Activity long-term goals are to determine the dependence of the mean climate, climate variability, and climate change on stratospheric dynamics as represented in Climate Models. Since the planning of the DynVar Workshop 1 (held in Toronto, Canada, 27-28 March 2008), a number of new works have appeared in the literature contributing to our knowledge on how stratospheric representation operates in climate models. In part because of these advancements, a few climate modeling groups are now planning to undertake the Coupled Model Intercomparison Project Phase 5 (CMIP5) experiments with models that include a well-resolved stratosphere. Interest in models with a well-resolved stratosphere has also led to the Stratosphere resolving Historical Forecast Project (SHFP), part of WCRP’s Climate Variability and Predictability Project (CLIVAR), aimed at quantify improvements in actual predictability by initialising and resolving the stratosphere in seasonal forecast systems.
The aim of the SPARC DynVar Workshop 2 was to provide a forum for discussing the scientific advancements in the key areas central to the Activity and for planning on how best the Activity can continue to advance the inclusion of a well-resolved dynamical stratosphere in Climate Models (coupled atmosphere ocean-seaice models) and Earth System Models (including also atmospheric chemistry and/or biogeochemical cycles).
Presentations were called for (but not restricted to) the following highlighted key areas:
- Influence of the stratosphere on the tropospheric circulation, on the ocean circulation via air-sea interactions, and on the cryosphere (in particular the sea ice field);
- Role of the stratosphere in the tropospheric circulation response to climate change, and the implications of this for oceanic and cryospheric climate change responses;
- Mechanisms of two-way stratosphere-troposphere coupling in climate models, to understand why the behaviors of models differ between each other.
Participation from modeling groups was called for:
- Presentation of the status of the CMIP5 runs with models with a well-resolved stratosphere;
- Discussion on how to best analyze, make full use, and exchange knowledge from the ensembles of CMIP5 runs, with the role of the stratosphere in focus;
- Discussion how to best analyze CLIVAR’s SHFP runs;
- New results and reports on experience gained from the analysis of the SPARC Chemistry-Climate Model
COMBINE project side event: The SPARC DynVar Workshop 2 is organized in collaboration with the COMBINE EC project. A COMBINE side event (by invitation) took place the day before the workshop, 2 November 2010. The COMBINE side event was kindly hosted by the National Center for Atmospheric Research (NCAR).
SPONSORS: CIRES, COMBINE, NOAA, NCAR, and SPARC’s WCRP.
DynVar Workshop Committe: E Manzini, M A Giorgetta, J Perlwitz, L M Polvani, F Sassi, and A Scaife
