Scaling regimes and linear/nonlinear responses of last millennium climate to volcanic and solar forcings [PDF]
Earth System Dynamics, 2016 At scales much longer than the deterministic predictability limits (about 10 days), the statistics of the atmosphere undergoes a drastic transition, the high-frequency weather acts as a random forcing on the lower-frequency macroweather.

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.

Radiative Forcing From the 2014–2022 Volcanic and Wildfire Injections
Geophysical Research Letters, 2023 Volcanic and wildfire events between 2014 and 2022 injected ∼3.2 Tg of sulfur dioxide and 0.8 Tg of smoke aerosols into the stratosphere. With injections at higher altitudes and lower latitudes, the simulated stratospheric lifetime of the 2014–2022 ...

Solar and volcanic forcing of North Atlantic climate inferred from a process-based reconstruction [PDF]
Climate of the Past, 2018 The effect of external forcings on atmospheric circulation is debated. Due to the short observational period, the analysis of the role of external forcings is hampered, making it difficult to assess the sensitivity of atmospheric circulation to ...

Geophysical Research Letters, 2019 Radiative forcing from volcanic aerosol impacts surface temperatures; however, the background climate state also affects the response. A key question thus concerns whether constraining forcing estimates is more important than constraining initial ...

Holocene glacier variations and their potential orbital, solar, volcanic and anthropogenic forcings
Лëд и снег, 2015 The magnitude of glacier advances generally increased in the Northern Hemisphere and decreased in the Southern Hemisphere over the Holocene. This trend can be explained be the orbital forcings. The exceptions are in some regions of the high Asia. 10–4 ka

Unraveling volcanic impacts in semi-arid climates: machine learning and CMIP6 insights from Krakatau and Santa Maria [PDF]
Scientific ReportsVolcanic eruptions are among the strongest natural climate forcings, yet their regional impacts remain poorly resolved, particularly in semi-arid hotspots.

Historical Simulations With HadGEM3‐GC3.1 for CMIP6
Journal of Advances in Modeling Earth Systems, 2020 We describe and evaluate historical simulations which use the third Hadley Centre Global Environment Model in the Global Coupled configuration 3.1 (HadGEM3‐GC3.1) and which form part of the UK's contribution to the sixth Coupled Model Intercomparison ...

Out-of-phase tropical Atlantic–Pacific response after volcanic eruptions over the Last Millennium in PMIP4/past1000 simulations [PDF]
Scientific ReportsThe Atlantic Niño, a key mode of tropical Atlantic variability, strongly influences precipitation over South America and Africa and interacts with Pacific El Niño through intricate ocean-atmosphere dynamics. Despite its significance, the Atlantic-Pacific
