Thursday 24 January 2002
0800-0830 Continental breakfast
0830-1200 Breakout groups. Topics suggested so far:
 
  • Simulation of major climate anomalies, 1950 (1900?) - 1998
  • Quality of SST data
  • Predictability of seasonal to decadal mean fields
  • Seasonal to interannual variability of the Asian monsoon, PNA, NAO (AO), PDO, etc.
  • Role of land surface conditions in prolonged drought
  • How should we use AGCMs and CGCMs together to study modes of climate variability?
1200-1400 Lunch
1400-1530 Reports of breakout groups
1530-1600 Break
1600-1730 Issues for future C20C investigations and diagnostics. Topics suggested so far:
 

INTEGRATIONS:

 
  • More complete forcing: changes in GHG, solar irradiation, volcanic effects, sulphate aerosols, etc.
  • Prescribing land surface characteristics (vegetation type and fraction, surface albedo, soil moisture)
  • Comparison of CGCM and AGCM integrations
  • Simple parameterization for sub-monthly SST variation
  DIAGNOSES:
 
  • Diagnosis of trends in extremes
  • Downscaling from large scale predictors
  • Validating interannual variability in AGCM simulations
  • Potentially predictable patterns of interannual variability
  ORGANIZATIONAL:
 
  • Interactions with CLIVAR program
