Stellar Convective Penetration: Parameterized Theory and Dynamical Simulations
The Astrophysical Journal, 2022 Abstract Most stars host convection zones in which heat is transported directly by fluid motion, but the behavior of convective boundaries is not well-understood. Here, we present 3D numerical simulations that exhibit penetration zones: regions where the entire luminosity could be carried by radiation, but where the temperature gradient ...

Control vector parameterization with sensitivity based refinement applied to baking optimization [PDF]
, 2007 In bakery production, product quality attributes as crispness, brownness, crumb and water content are developed by the transformations that occur during baking and which are initiated by heating. A quality driven procedure requires process optimization

Can We Use 1D Models to Predict 3D Model Response to Forcing in an Idealized Framework?
Journal of Advances in Modeling Earth Systems, 2022 Single‐column models (SCMs) simulations are sometimes used to evaluate model physics and aid parameterization development. However, few studies have systematically compared SCM behavior—where column boundary conditions are specified—with that of ...

A unified parameterization of clouds and turbulence using CLUBB and subcolumns in the Community Atmosphere Model [PDF]
Geoscientific Model Development, 2015 Most global climate models parameterize separate cloud types using separate parameterizations. This approach has several disadvantages, including obscure interactions between parameterizations and inaccurate triggering of cumulus parameterizations ...

Improving the representation of shallow cumulus convection with the simplified-higher-order-closure–mass-flux (SHOC+MF v1.0) approach [PDF]
Geoscientific Model Development, 2023 Parameterized boundary layer turbulence and moist convection remain some of the largest sources of uncertainty in general circulation models. High-resolution climate modeling aims to reduce that uncertainty by explicitly attempting to resolve deep moist ...

A Cloud Model to Parameterize Convection [PDF]
Journal of Applied Meteorology, 1973 Abstract This paper describes a parameterization of convection developed for use with a multi-level primitive equation model of the atmosphere. This parameterization is similar in form to that of Kuo, who postulates that boundary layer air rises moist adiabatically before mixing with the large-scale flow.

Dependence of MJO Predictability on Convective Parameterizations [PDF]
Journal of Climate, 2020 AbstractThis study revisits MJO predictability based on the “perfect model” approach with a contemporary model. Experiments are performed to address the reasons for substantial uncertainties in current estimates of MJO predictability, with a focus on the influence of atmospheric convection parameterization.

Impact of multiple radar reflectivity data assimilation on the numerical simulation of a flash flood event during the HyMeX campaign [PDF]
, 2017 An analysis to evaluate the impact of multiple radar reflectivity data with a three-dimensional variational (3-D-Var) assimilation system on a heavy precipitation event is presented. The main goal is to build a regionally tuned numerical prediction model
