CORDEX Science Advisory Team 2nd Session
25-27 February 2015
SMHI, Norrkoping, Sweden
Outline
Development Activities and Applications
• Coordination of CORDEX South Asia
• Dissemination of CORDEX South Asia data sets
assessments and development of adaptation strategies
for
impact
• Development of an Earth System Grid (ESG) node at CCCR-IITM
Basic Research and Development of Regional Capacity
• The role of the Indo-Pacific sea surface temperature anomalies on the
heavy precipitation over northwest India-Pakistan region
• Recent Past Summer Monsoon Season Climate Response to Anthropogenic
Forcings
• Observed changes in western disturbances over the Western Himalayas in
recent decades
CORDEX South Asia Co-ordination
• Development of multi-model ensemble projections of high resolution (50km)
regional climate change scenarios for South Asia
• Generation of regional climate projections at CCCR-IITM
• LMDZ variable grid global climate model
• RegCM4 regional climate model
• Co-ordination with partner institutions for multi-model
ensemble projections – SMHI, IAES, CSC, CSIRO, ICTP…
• Development of an Earth System Grid (ESG) node at
CCCR-IITM for CORDEX South Asia
• Archival, Management, Retrieval, Dissemination of CORDEX South Asia data
• Evaluation of regional climate projections over South Asia
• to provide relevant and reliable regional climate change information for
effective harnessing of science-based climate information by Vulnerability,
Impact & Adaptation (VIA) community
• Development of regional capacity for assessment of regional climate change

Summary
• Better identification and illustration of the added value of regional
downscaling in the framework of CORDEX South Asia
• Process-based analysis and validation with observations
• Uncertainty estimation of regional climate projections from ensemble
simulations
• Improved representation of the effects of regional forcing, such as
land-use and aerosols
• Data dissemination through ESGF, regional capacity building and training
workshops
• Development of end-to-end (climate to end-users) projects.
Thank you very much
