Climate variability poses growing threats to human lives and socio-economic activities through changes in frequency and intensity of abnormal weather such as cold/heat waves and floods/droughts. This involves several climate phenomena with a wide range of timescales from subseasonal to decadal variations (e.g. MJO, IOD, ENSO, PDV, AMV). Many efforts have been made for understanding and predicting climate variations on each timescale, but there remain large uncertainties in simulation and prediction of subseasonal to decadal climate variations. This highlights lack of understanding of weather and climate interaction across different spatial and temporal timescales (e.g. tropical cyclones and ENSO) as well as multiple physical processes underlying climate variations (e.g. troposphere-stratosphere coupling, air-sea-ice interaction). This session aims to share current knowledge of subseasonal to decadal climate variability and predictability in order to identify the unresolved issues for better understanding and accurate prediction. This session invites all the abstracts related to the observational, theoretical, process-level and modelling research on subseasonal to decadal climate variability and predictability.
