WCRP/SPARC workshop announcement: Challenges for Climate Science – Synergies between SPARC and the WCRP Grand Challenges

Place and dates: Berlin, Germany – 31 October to 1 November 2016
Abstract submission and registration deadline: 30 Sep 2016


Motivation and goals

In recent years the World Climate Research Program (WCRP) has identified several Grand Science Challenges (http://www.wcrp-climate.org/grand-challenges) representing areas of emphasis in scientific research for WCRP in the coming decade. Progress in these areas should lead to “actionable information” for decision makers. More broadly, WCRP supports climate science via its Core Projects, among them the SPARC project on “Stratosphere-troposphere processes and their role in climate” .

Held back-to-back with the annual meeting of the SPARC scientific steering group, this workshop tries to bring 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.


Contributions

We call for scientific contributions related to

  • the Grand Challenges on “Clouds, circulation & climate sensitivity”, “Climate extremes”, “Near-term predictability”, and “Carbon feedbacks in the climate system”,

and/or

  • the SPARC themes “Atmospheric dynamics and predictability”, “Chemistry and climate”, and “Long-term records for climate understanding”.

Please submit a short abstract by 30 September 2016 by email to .

Most contributions will be presented in poster format.


Confirmed invited speakers

Guy Brasseur, Andrew Charlton-Perez, Bill Collins, Dim Coumou, George Craig, Daniela Domeisen, Hella Garny, Corinna Hoose, Wolfgang Müller, Olivia Romppainen, Gabriele Stiller, Claudia Timmreck, Ted Shepherd

Application deadline: 30 Aug 2016

The Max Planck Institute for Meteorology (MPI-M) is a multidisciplinary centre for climate research located in Hamburg, Germany. It has an internationally recognised reputation in climate modelling. The MPI-M is located in the heart of one of Europe’s most livable and vibrant cities. It provides a highly international and interdisciplinary environment for conducting scientific research as well as access to state-of-the-art scientific and computational facilities.

Within the German Ministry for Education and Research (BMBF) funded collaborative JPI Climate-Belmont project “The potential of seasonal-to-decadal-scale inter-regional linkages to advance climate predictions” (InterDec-MPI), the department for The Ocean in the Earth System (Director’s research group) is looking for a

Postdoctoral Scientist/Research Scientist (m/f, Ref. W029)

to investigate the inter-linkages among seasonal-to-decadal scale variability in the Arctic, mid-latitudes and tropics, their mechanisms and their implications for reliable climate predictions through coordinated multi-model sensitivity experiments and suites of initialized climate predictions. The project InterDec-MPI coordinates the research activities of an international consortium of European and Asian elite universities and research climate centers within the Belmont Forum/JPI-Climate initiative "Climate services collaborative
research action on climate predictability and inter-regional linkages" (http://www.jpi-climate.eu/2015projects/interdec).

Specific objectives of InterDec are

  • To investigate the mechanisms that govern the fast atmospheric linkages through both tropospheric and stratospheric processes between polar and lower latitudes and explore the potential for predictions on sub-seasonal to seasonal time scales.
  • To advance our understanding of how frequency and amplitude of extreme weather events can be modulated by decadal-multidecadal changes in the background climate conditions.
  • To explore the role of the ocean for low frequency signal communication between high and low latitudes and the implications for decadal predictability.
  • To explore the added value of increased climate model resolution for a more realistic representation of processes linking high and low latitudes and for enhancing the predictability of high-impact climate and extreme weather events on regional scales.

Responsibilities

  • Develop original research and analysis strategy to address research questions relevant to the InterDec project objectives.
  • Conduct and analyze coordinated sensitivity and hindcast climate simulations with the Max Planck Earth System Model aimed at improving our understanding of Arctic-Midlatitude-Tropics linkages at seasonal-to-decadal time scale and their potential predictability, with a focus on monsoon systems, Eurasian climate extremes and hiatus like events.
  • Contribute to project and task coordination, as well as to the writing and assembling of project reports.
  • Disseminate the results through publications in high-impact peer-reviewed journals and presentations at project annual meetings, national and international conferences.
  • Attend training, coordination, and dissemination activities that are organized by InterDec.

Qualifications /experience

  • A PhD in Meteorology, Oceanography, Physics, or a related area is required for this position.
  • Good knowledge of climate dynamics and predictability, in particular of atmospheric and/or ocean dynamics, atmosphere/ocean interactions and teleconnections. Expertise in initialising and evaluating the skill of seasonal-to-decadal climate predictions is an advantage.
  • Experience in performing and evaluating coupled atmosphere-ocean
system simulations is desired.
  • Programming skills in Fortran and statistical post-processing (e.g. cdo, R) and visualization software (e.g. MATLAB, FERRET, NCL, IDL, GRADS), as well as experience in handling large climate data sets.

Call for Abstracts: Atmospheric Chemistry in the Anthropocene: Faraday Discussion in York, UK – 22-24 May 2017

Oral abstracts submission deadline: 5 Sep 2016


Introduction

Human activities have greatly impacted the Earth system so much so that it has ushered in a new epoch – the Anthropocene. The consequent changes – observed and predicted – occur in the oceans, the terrestrial regions, and the biosphere, and have raised important societal issues such as climate change, ocean acidification, air quality degradation, and ozone layer depletion.

The central component that leads to changes and impacts are the processes that alter the composition of the atmosphere. It is time to take a closer look at the processes that change the composition the Earth’s atmosphere to ensure that they are understood and represented accurately in models, whose predictions underpin societal actions.

This Discussion will focus on emerging issues such as interactions between anthropogenic and biogenic emissions, new mechanisms important for atmospheric chemistry, the impacts of climate on air quality, and new instrumental tools and platforms for atmospheric chemistry.


Aims

This meeting aims to bring together a global network of experimentalists, field scientists, theoreticians, chemists, physicists and environmental scientists working at the forefront of these emerging issues, providing a forum for cross-disciplinary exchange and discussion of ideas on the processes that control the composition of the atmosphere.


Themes

Atmospheric chemistry and the biosphere
In this session we will explore ocean-atmosphere and land-atmosphere interactions; new emission mechanisms and feedbacks.

Atmospheric chemistry processes

In this session we will discuss new mechanisms of importance for atmospheric chemistry, including radical chemistry and recycling, Criegee intermediates, gas phase precursors to SOA, and nitrogen cycling.

The air we breathe: Past, present, and future

This session will look at air quality-climate interactions; developing world issues; short-lived climate forcers. We will discuss air pollution extremes in the 21st century, the benefits of reducing short-lived climate pollutants, environmental pollution in developing nations.

New tools for Atmospheric Chemistry
In this final session we aim to explore the new tools and strategies available, including new measurement techniques, platforms, modelling tools and paradigms.
