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.

Forced changes in a Tibetan lake ecosystem over the past millennium [PDF]
Nature CommunicationsAquatic ecosystems have changed dramatically, but the relative roles of external forcings and internal atmospheric variability remain unclear. Here, using Tibetan lake ecological reconstructions and Earth system simulations, we reveal how shared external

Role of volcanic forcing on future global carbon cycle [PDF]
Earth System Dynamics, 2011 Using a fully coupled global climate-carbon cycle model, we assess the potential role of volcanic eruptions on future projection of climate change and its associated carbon cycle feedback.

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.

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

Frontiers in Plant Science, 2023 The vegetation carbon uptake plays an important role in the terrestrial carbon cycle on the Qinghai–Tibet Plateau (QTP), while it is extremely sensitive to the impact of natural external forcings.

On the detection of the solar signal in the tropical stratosphere [PDF]
Atmospheric Chemistry and Physics, 2014 We investigate the relative role of volcanic eruptions, El Niño–Southern Oscillation (ENSO), and the quasi-biennial oscillation (QBO) in the quasi-decadal signal in the tropical stratosphere with regard to temperature and ozone commonly attributed ...

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 ...

Impact of solar versus volcanic activity variations on tropospheric temperatures and precipitation during the Dalton Minimum [PDF]
Climate of the Past, 2014 The aim of this work is to elucidate the impact of changes in solar irradiance and energetic particles versus volcanic eruptions on tropospheric global climate during the Dalton Minimum (DM, AD 1780–1840).

Investigation of weather anomalies in the low-latitude islands of the Indian Ocean in 1991 [PDF]
Annales Geophysicae, 2015 Temperature, precipitation and sunshine duration measurements at meteorological stations across the southern Indian Ocean have been analysed to try to differentiate the possible influence of the Mount Pinatubo volcanic eruption in the Philippines in ...
