1. World Climate Research Programme Progress and Plans Ghassem R. Asrar & Antonio J. Busalacchi

2. Background WCRP Independent Review by its Sponsors- 2008-2009 WMO Planning for the Global Framework for Climate Services- 2009-Present ICSU Visioning for Environmental research and Global Sustainability, Future Earth- 2010-Present IOC/UNESCO OcenObservation Symposium leading to development of Integrated Framework for Sustained Ocean Observations (IFSOO) – 2009-Present The WCRP Joint Scientific Committee initiated strategic planning and consultation- 2008-Present Shaping plans and priorities for next decade.

3. Research Contributions: Way Forward Maintain scientific objectivity and excellence as a foundation for science-based climate information. Establish an effective dialogue with users of climate information to understand their needs and to obtain their feedback on use of available knowledge, and required new information. Facilitate the holistic approach to Earth climate system research to include socioeconomic aspects of the problems, and decision processes. Provide greater support to research capacity development with special focus on regional aspects of climate variability and change. Promote solution-based approach to addressing challenges and opportunities in developing, evaluating and disseminating climate information for risk management, adaptation planning and global sustainability and development.

4. Urgent need for actionable climate information based on sound science The need for “symbiotic” relationship between providers and users of climate information to ensure climate information is timely, accessible, easy to understand Urgent need for training and development of next generation of scientists and decision makers who pursue and promote the use of actionable climate/environmental information Stakeholders and User Perspective

5. WCRP Grand Science Challenges Provision of skillful future climate information on regional scales Sea-Level Change and its regional implications Cryosphere response to climate change The role of clouds, aerosols, precipitation, and radiation in climate sensitivity Water availability and distribution in a changing climate Science foundation for prediction and attribution of extreme events

6. Mission & Objectives World Climate Research Programme coordinates international climate research to improve; (1)climate predictions and (2)our understanding of human influence on climate “for use in an increasing range of practical applications of direct relevance, benefit and value to society” (WCRP Strategic Framework 2005-2015).

7. Emerging Structure Post-2013 The WCRP will focus on four fundamental interactions of the Earth/climate system: –Ocean-atmosphere –Land-atmosphere –Stratosphere-troposphere –Cryosphere and Climate WCRP Overarching/Unifying themes: - Observation and Analysis - Process understanding -Model development, projections and prediction -Climate Information and Application

10. Opportunities and Challenges; Support development of climate information for decision makers; Develop seamless regional and intera-seasonal to inter-annual, and decadal climate prediction/projection; Promote and enable timely, reliable, and easy to access climate information and knowledge; and Support education, training and development of next generation of climate experts and networks. International cooperation and Coordination is key to success. Summary

12. WMO Background/Rationale Executive Council Task Team on Research Aspects of an Enhanced Climate, Weather, Water and Environmental Prediction Framework, 2009 – Coordinate and Accelerate Prediction Research: develop a unified approach to multidisciplinary weather, climate, water and environmental prediction research, step up high-performance computing investments to accommodate the increasing complexity and detail of models, accelerate the development, validation and use of prediction models – Link Research, Operation and Service Delivery: Develop closer linkages between research, operations and users through Forecast Demonstration Projects (FDPs) that accelerate technology transfer – The Role of WMO Commissions: Implement a process to review and rationalise the roles and mandates of the Commissions, and to improve their effectiveness in enhancing WMO Member capabilities in research, observations, prediction and services

15. WMO Polar Prediction Project (PPP)  Objective:  “Promote cooperative international research enabling development of improved weather and environmental prediction services for the polar regions, on time scales from hourly to seasonal” (contribution to WMO GIPPS)  Research components:  observations, modeling, data assimilation, ensemble forecasting  predictability, diagnostics, teleconnections  societal and economic research applications, verification  Implementation: Year of Polar Prediction (YOPP) – period 2017-2018  Synergies with the WCRP Polar Climate Predictability Initiative (PCPI)  Project Office: under discussion  Trust fund: contributions welcome Courtesy T. Jung, AWI Side Event on Monday!

16. WCRP Polar Climate Predictability Initiative (PCPI) WMO GIPPS (G lobal I ntegrated P olar P rediction S ystem ) Research on Ice Sheets and Sea Level WWRP Polar Prediction Project (PPP) Research Tasks Understand past polar climate variations, (palaeo, up to 100 years) Assess re-analyses products in polar regions Understand polar climate predictability on seasonal to decadal timescales Assess perfor- mance of CMIP5 models in polar regions Model error Understand how jets and non- zonal circulation couple to the rest of the climate system in the Southern Hemisphere Days -> Months -> Years -> Decades -> Centuries

17. 17 Sand and Dust Storm Warning and Advisory System(SDS-WAS)  Objectives :  To enhance the ability of countries to deliver timely and quality forecasts of sand and dust storms, observations of aerosols; sand and dust information and knowledge to users through an international partnership of research and operational experts and users  MERIT Meningitis Project and TIGGE/Meningitis web-page http://tparc.mri-jma.go.jp/TIGGE/tigge_meningitis.html  New SDS-WAS Node is in USA  UNEP-WMO Collaboration on SDS-WAS in West Asia  The SDS-WAS Research Implementation Plan : in final stage  Financial Support : Currently from the regular WMO budget, but in future from the voluntary contributions (via trust fund).
