Climate Modes in the Past
Convenors
Ed Hathorne, Nerilie Abram, Manish Tiwari, Thomas Felis
Description
Important climate modes such as the El Niño-Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), the Indian Ocean Dipole (IOD), the Pacific Decadal Oscillation (PDO), the Southern Hemisphere Annual Mode (SAM), and the monsoon systems are characterised by seasonal, inter-annual, decadal and centennial variability. Improving our understanding of these natural modes of variability is essential as they modulate droughts and floods on time scales relevant to society.
Reconstructing this high frequency variability is a challenge that can be addressed with analyses of annually banded archives such as coral skeletons, trees or bivalves as well as with ice cores, speleothems and various components of high accumulation rate or varved sediments. Other studies are applying geochemical analyses of many individual foraminifera shells to investigate seasonal and inter-annual variability in the past ocean. This session welcomes contributions investigating seasonal to centennial climate modes in the past, whether through modeling or high resolution proxy records extracted from marine or terrestrial climate archives. In particular, we encourage contributions combining different archives and climate model simulations.
