JM 2 - CLIMATE VARIABILITY AND CHANGE ON ALL SCALES (IAMAS, IAPSO)

Convenor – Fei Fei Jin
Co-convenors - Andrew Charlton-Perez, Seok-Woo Son, Hisashi Nakamura, Noel Keenlyside, Babatunde Abiodun

Instrument records revealed that our earth climate system features rich climate variability dominated by climatic modes from sub seasonal to multi-decadal timescales. They include, but not limited to, El Niño and Southern Oscillation (ENSO), ENSO and Annual Cycle Combination mode, Pacific Decadal and Inter-decadal Oscillation/Variability, Pacific Meridional Modes, Indian Ocean Dipole and Indian Ocean Basin modes, Atlantic Meridional mode and Atlantic Multi-decadal Oscillations, as well as Arctic Oscillation and Antarctic Oscillations, North Pacific Oscillation, North Atlantic Oscillations, Pacific North/South America Patterns, Madden Julian Oscillation etc.  These modes, dominating natural climate variability and mostly subjecting to and projecting on climate change, have great global impacts including the upper atmosphere, and form the main sources for sub-seasonal to decadal climate predictability.

In this session, we welcome papers of observational, diagnostic, and theoretical analyses, modelling, prediction and predictability studies of the modes of climate variability.  We also welcome studies on the interaction of climatic modes their changes under global warming, and their global and regional impacts.
