Climate Scenarios:What are they ? A climate scenario is a plausible representation of future climate that has been constructed for explicit use in investigating the potential impacts of anthropogenic climate change. NATCOM Project Mid-term Evaluation - 27.02.2003
Uncertainties in Climate Scenarios • Specifying alternative emissions futures • Uncertainties in converting emissions to concentrations • Uncertainties in converting concentrations to radiative forcing • Uncertainties in modelling the climate response to a given radiative forcing • Uncertainties in converting model response into inputs for impact studies NATCOM Project Mid-term Evaluation - 27.02.2003
Climate System NATCOM Project Mid-term Evaluation - 27.02.2003
Climate Models • Simplified mathematical representation of the Earth’s climate system • Skill depends on the level of our understanding of the physical, geophysical, chemical and biological processes that govern the climate system • Substantial improvements over the last two decades • Sub-models : atmosphere, ocean, land surface, cryosphere, biosphere • Typical Resolution of global models (atmosphere) : Horizontal - 250 km; Vertical – 1 km • Small-scale processes : Parameterization • Coupled models (e.g., atmosphere-ocean) • Sensitivity studies/Future projections • Internal variability/Ensemble runs NATCOM Project Mid-term Evaluation - 27.02.2003
IS92A Scenarios of Rainfall and Temperature over India Using greenhouse gas forced (following IS92A scenarios) simulations of 8 different coupled ocean-atmopshere general circulation models, the rainfall and temperature scenarios for 2061-80 compared to the baseline period of 1961-90 are presented in the following figures for the Indian region. The simulations of eight models used are: 1. Canadian Center for Climate modeling (CCC) model. 2. Center for Climate Research studies (CCSR) model. 3. Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO) model. 4. Deutsches Kilma Rechen Zentrum (DKRZ) model. 5. Geophysical Fluid Dynamics Laboratory (GFDL) model. 6. Hadley Centered model.(HadCM3) 7. Max-planck Institute(MPI) model. 8. National Center for Atmospheric Research (NCAR) model. NATCOM Project Mid-term Evaluation - 27.02.2003
