Do GCMs predict the climate ... or macroweather? [PDF]
Earth System Dynamics, 2013 We are used to the weather–climate dichotomy, yet the great majority of the spectral variance of atmospheric fields is in the continuous "background" and this defines instead a trichotomy with a "macroweather" regime in the intermediate range from ≈10 ...

Skillful prediction of multidecadal variations in volcanic forcing [PDF]
Geophysical Research Letters, 2017 AbstractStratospheric sulfate injections from explosive volcanic eruptions are a primary natural climate forcing. Improved statistical models can now capture and simulate dynamical relationships in temporal variations of binary data. Leveraging these new techniques, the presented analysis clearly indicates that the number of large eruptions in the most

A regional climate palaeosimulation for Europe in the period 1500–1990 – Part 1: Model validation [PDF]
Climate of the Past, 2013 We present and analyse a high-resolution regional climate palaeosimulation encompassing the European region for the period 1500–1990. We use the regional model MM5 driven at the boundaries by the global model ECHO-G.

Monitoring diffuse volcanic degassing with seismic ambient noise [PDF]
Natural Hazards and Earth System SciencesDiffuse volcanic degassing is a persistent and often underestimated natural hazard, with potential impacts on air quality, ecosystem health, and volcanic risk management.

Stratospheric age of air variations between 1600 and 2100
Geophysical Research Letters, 2016 The current understanding of preindustrial stratospheric age of air (AoA), its variability, and the potential natural forcing imprint on AoA is very limited.

The Detection and Attribution Model Intercomparison Project (DAMIP v1.0) contribution to CMIP6 [PDF]
Geoscientific Model Development, 2016 Detection and attribution (D&A) simulations were important components of CMIP5 and underpinned the climate change detection and attribution assessments of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. The primary goals

Volcanic forcing of the Lomagundi–Jatuli carbon isotope excursion [PDF]
Proceedings of the National Academy of SciencesThe Lomagundi–Jatuli Event (LJE), Earth’s most pronounced and prolonged positive carbon isotope excursion, followed the Great Oxidation Event and remains enigmatic in origin. We present a Pb–Pb isochron age of 2,194 ± 5 Ma for black shales from the Francevillian FB Formation, Gabon—an LJE type locality—coinciding with the ...

Timing and climate forcing of volcanic eruptions for the past 2,500 years [PDF]
Nature, 2015 Volcanic eruptions contribute to climate variability, but quantifying these contributions has been limited by inconsistencies in the timing of atmospheric volcanic aerosol loading determined from ice cores and subsequent cooling from climate proxies such as tree rings.

The impact of volcanic aerosol on the Northern Hemisphere stratospheric polar vortex: mechanisms and sensitivity to forcing structure [PDF]
Atmospheric Chemistry and Physics, 2014 Observations and simple theoretical arguments suggest that the Northern Hemisphere (NH) stratospheric polar vortex is stronger in winters following major volcanic eruptions.
