3. Deliverables 1.Extension and improvement of the climate record Priority Actions: -Support regional and international reanalysis efforts -Facilitate the recovery of historical terrestrial and marine global observations -Compile well-dated proxy-based paleo-climate records of seasonal to multi-decadal resolution over the last two millennia for the Arctic and all continents including the adjacent ocean regions

4. Priority Actions (cont): –Produce regional-scale reconstructions of seasonal variations in temperature, precipitation, and atmospheric pressure fields –Compare climate reconstructions with the results of transient simulations of state-of-the-art General Circulation Models Leads (tentative): WCRP, IGBP, Japan, USA, ECMWF, GCOS

5. Priority Actions: Continue to carry out the activities outlined in the Year of Tropical Convection (YOTC) Implementation Plan (www.ucar.edu/yotc).www.ucar.edu/yotc Further progress the objectives of the YOTC Task Force on the Madden Julian Oscillation (YOTC MJO TF) including further development of process oriented diagnostics/metrics that provide insight into the physical mechanisms for robust simulation of the MJO Initiate the sub-seasonal to seasonal prediction project Initiate the polar prediction project - see final meeting report at www.wmo.int/thorpex www.wmo.int/thorpex Leads (tentative): WMO, WCRP Deliverable 2. Weather, Climate, Earth-System Prediction Systems

6. Deliverables 3.A global climate information service Priority Actions: - Ensure the delivery of climate information needed for adaptation through the GEO Portal Build on existing climate services such as the US climate portal (climate.gov), WMO Climate Services Framework To be implemented in connection with IN-01 (GCI) Leads: TBC

7. Deliverables 4.Availability of Essential Climate Variables Priority Actions: -Accelerate the implementation of the Global Climate Observing System -Strengthen the climate-related functions and activities of global atmospheric, oceanic and terrestrial observing systems Leads (tentative): GCOS, USA, CEOS

11. Tropical Cyclone Occurrence during YOTC (courtesy of Julian Hemming, UK Met Office) Nargis, landfall over Myanmar, huge storm surge, 100,000 lives 3 landfalls in Mexico Ike - Largest size & Marko - smallest TC ever in this basin El Nino modulation Parma, torrential rainfall Rick, 2 nd strongest in E. Pacific ever Grace, heavy rainfall over Europe

12. The tropical atmosphere-ocean-land systems have never been so well observed. Modeling resources are rapidly improving. Satellite Observations ( e.g., EOS ) In-Situ Networks ( ARM, CEOP ) GOOS ( e.g., TAO, PRADA, drifters) IOPs ( e.g., VOCALS, T-PARC, AMY ) High-Resolution Deterministic Forecast Models & Global Analyses Research e.g., regional to global Cloud-system Resolving Models (CRM), theoretical-dynamical models New/Improved Resources T-PARC

16. Inclusion of New Proposals Sub-seasonal to seasonal prediction (WMO/WCRP) Polar prediction programme (WMO/WCRP)

17. Resources Available for Implementation (current status and in planning) YOTC Programme Office Participating Organisations and Universities (research)

18. Issues and Gaps In terms of climate prediction, it needs to formulate and initiate the polar and seasonal activities for the weather and climate prediction system. Workshops have identified key actions these now need to be taken forward. Global observations (ECVs) will be represented across the Work Plan

19. Issues and Gaps On the climate information service, it is suggested that the term of service would be replaced by system to make the deliverable be more specific and explicit, and to avoid the duplication with other initiatives. Potentially, the 5 th deliverable can be suggested with the title of Climate Change Adaptation Measure.
