Observationally Constrained Cloud Phase Unmasks Orbitally Driven Climate Feedbacks
Geophysical Research Letters, 2021 The mechanisms which amplify orbitally driven changes in insolation and drive the glacial cycles of the past 2.6 million years, the Pleistocene, are poorly understood.

Environmental Research Communications, 2023 In the Earth system models (ESMs) participating in the Coupled Models Intercomparison Project phase 6 (CMIP6), the tropical low-cloud feedback is 50% more positive than its predecessors (CMIP5) and continues to dominate the spread in simulated climate ...

Acidity and the multiphase chemistry of atmospheric aqueous particles and clouds [PDF]
Atmospheric Chemistry and Physics, 2021 The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry.

Investigating the impact of cloud-radiative feedbacks on tropical precipitation extremes
npj Climate and Atmospheric Science, 2021 Although societally important, extreme precipitation is difficult to represent in climate models. This study shows one robust aspect of extreme precipitation across models: extreme precipitation over tropical oceans is strengthened through a positive ...

The impact of parametrized convection on cloud feedback [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 We investigate the sensitivity of cloud feedbacks to the use of convective parametrizations by repeating the CMIP5/CFMIP-2 AMIP/AMIP + 4K uniform sea surface temperature perturbation experiments with 10 climate models which have had their convective parametrizations turned off.

An underestimated negative cloud feedback from cloud lifetime changes
Nature Climate Change, 2021 As the atmosphere warms, part of the cloud population shifts from ice and mixed-phase (‘cold’) to liquid (‘warm’) clouds. Because warm clouds are more reflective and longer-lived, this phase change reduces the solar flux absorbed by the Earth and constitutes a negative radiative feedback.

A cloud feedback emulator (CFE, version 1.0) for an intermediate complexity model [PDF]
Geoscientific Model Development, 2017 The dominant source of inter-model differences in comprehensive global climate models (GCMs) are cloud radiative effects on Earth's energy budget. Intermediate complexity models, while able to run more efficiently, often lack cloud feedbacks.

Journal of Advances in Modeling Earth Systems, 2023 Radiative‐convective equilibrium (RCE) is particularly well suited for studying tropical deep‐convection, a regime of clouds that contributes some of the highest uncertainties to the estimates of total cloud feedback.

Technical note: Recommendations for diagnosing cloud feedbacks and rapid cloud adjustments using cloud radiative kernels [PDF]
Atmospheric Chemistry and PhysicsThe cloud radiative kernel method is a popular approach to quantify cloud feedbacks and rapid cloud adjustments to increased CO2 concentrations and to partition contributions from changes in cloud amount, altitude, and optical depth.

Molecular cloud evolution – V. Cloud destruction by stellar feedback [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We present a numerical study of the evolution of molecular clouds, from their formation by converging flows in the warm ISM, to their destruction by the ionizing feedback of the massive stars they form. We improve with respect to our previous simulations by including a different stellar-particle formation algorithm, which allows them to have masses ...
