Past and Future Collaboration with ECMWF, Evaluation of Re-analyses and
NWP
Previous and Current Work
• Member State Special ProjectsProvide access to ECMWF resources, super computer, storage and MARS archive, to conduct studies of mutual interest.Several previous special projects in collaboration with Hamburg (Bengtsson, Keenlyside):-1. Sensitivity of ERA40 to different observing systems and the determination of the
global water cycle. Evaluation of climate trends.2. Predictability studies with emphasis on extra-tropical and tropical storm tracks and
their dependence on the global observing systems. Lizzie Froude.3. Changes in Precipitation Extremes Associated with Extra-tropical Cyclones: System
Centered Dynamical Downscaling. Adrian Champion.
Examples-Observing System Experiments
NH Z500 SH Z500
Previous and Current Work
• Other ProjectsMake extensive use of MARS archive for accessing re-analysis and operational analysis data.1. ERA-Interim, faster to use MARS than the web pages. Studies of hydrological
cycle, high latitude moisture and energy budgets, tropical and extra-tropical cyclones, polar lows.
2. Operational data, predictability studies of ensemble and deterministic systems for extra-tropical cyclones (Lizzie Froude), tropical cyclones (Emerton, Hodges), polar lows (Zappa).
3. ATHENA, collaboration with Thomas Jung and COLA. Integrations for decadel periods, including climate change, using simulations of the IFS at resolutions from T159(125km)-T1279(16km). Studies of tropical and extra-tropical cyclones.
4. Matt Hawcroft (PhD), “Evaluating latent heat release in extratropical cyclones from high-resolution climate models, remote sensing and global reanalyses”, collaborating with Richard Forbes (ECMWF) to produce output from the ERA-Interim system for input to COSP (CLOUDSAT, ISCCP).
5. TIGGE, easier to access via MARS for large quantities of data:1. Lizzie Froude, predictability studies of extra-tropical cyclones in TIGGE.2. Predictability studies of tropical cyclones in TIGGE (Emerton, Hodges).
Examples-TIGGE (Extra-tropical cyclones)
Examples-TIGGE (Tropical cyclones)
Future Work
1. Special project continuation on downscaling for hydrological models (DEMON).
2. Further observing system experiments with ERA-Interim and ERA-CLIM.3. Predictability studies with ERA-Interim and ERA-CLIM, i.e. experiments
with both the deterministic and ensemble systems.4. Possible collaboration on MINERVA, the follow up to ATHENA.5. Further studies of predictability using data from the operational system
and TIGGE, extra-tropical transition, meso-cyclones (polar lows, medicanes)
