Session A3: Statistical Methods/Machine Learning techniques for regional climate modelling/downscaling
Tuesday 26 September 15.30-17.15 CEST
Location: SISSA Main Auditorium
Session co-chairs: Fatima Driouech, Jason Evans and Douglas Maraun
Rapporteurs: Peace Olubukunmi Awoleye and AJ Komkoua Mbienda
Empirical statistical downscaling (ESD) methods follow a wide range of approaches (PP, MOS and bias adjustment, weather generators) and techniques (analogs, regression, machine learning). . These are applied individually or in combination to produce regional/local information from global or regional model outputs. Hybrid RCM-ESD methods (such as emulators) are an emergent topic boosted by developments in deep machine learning. Some key questions:
Can we evaluate the suitability and added value of statistical downscaling methods for climate change applications? Can we produce comprehensive intercomparisons to understand their benefits and limitations? Can we build RCM emulators suitable for certain tasks (e.g. emulating CPRCM runs or producing large ensembles)? How do we solve distillation issues from ESD/RCM/GCM ensembles?
