The Two‐Energies Turbulence Scheme Coupled to the Assumed PDF Method
Journal of Advances in Modeling Earth Systems, 2022 An update of the two‐energy turbulence scheme is presented, the 2TE + APDF scheme. The original version of the two‐energy scheme is able to successfully model shallow convection without the need of an additional parameterization for non‐local fluxes ...

Geophysical Monograph Series, Page 435-447., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Global climate impacts of stochastic deep convection parameterization in the NCAR CAM5
Journal of Advances in Modeling Earth Systems, 2016 In this study, the stochastic deep convection parameterization of Plant and Craig (PC) is implemented in the Community Atmospheric Model version 5 (CAM5) to incorporate the stochastic processes of convection into the Zhang‐McFarlane (ZM) deterministic ...

Evaluating Shallow Convection Parameterization Assumptions With a qt–w Quadrant Analysis
Journal of Advances in Modeling Earth Systems, 2023 Uncertainties associated with the response of shallow clouds to global warming remain a great challenge for climate projection. Due to the small size of these clouds, parameterizations are required to represent them in both current‐ and next‐generation ...

On bulk models of shallow cumulus convection [PDF]
Journal of the Atmospheric Sciences, 2005 Abstract Two-layer bulk models of the cloudy boundary layer are investigated, focusing on the consistency issues between common assumptions on the turbulent mixing and the thermodynamic profiles. Simplifications of the vertical structure of the conserved variables are shown to lead to inconsistent steady states. First, linear profiles in

The Role of Passive Cloud Volumes in the Transition From Shallow to Deep Atmospheric Convection
Geophysical Research Letters, 2023 Properly capturing the transition from shallow to deep convection remains a major shortcoming of numerical weather and climate models due to poor understanding of the physical processes controlling this transition. Although recent studies suggest shallow
