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.

Basic convective element: bubble or plume? A historical review [PDF]

Atmospheric Chemistry and Physics, 2014
During the 1950s and 1960s, when intensive investigations on atmospheric moist convection were launched, two possibilities were identified for the basic element of moist convection: bubble and plume.

Multi‐Grid Nesting Ability to Represent Convections Across the Gray Zone

Journal of Advances in Modeling Earth Systems, 2019
This study investigated the multi‐grid nesting ability of a limited area model to effectively represent convections across the gray zone, the resolution around 1–10 km where both cumulus parameterization and explicit convection are problematic.

Dependence of Convective Cloud Properties and Their Transport on Cloud Fraction and GCM Resolution Diagnosed from a Cloud-Resolving Model Simulation

Journal of Marine Science and Engineering, 2022
The scale-aware convective parameterization for high resolution global climate models must satisfy the requirement that the parameterized subgrid convective transport diminishes as the model resolution increases to convection-resolving resolutions.

Multiple Equilibria in a Single-Column Model of the Tropical Atmosphere

, 2007
A single-column model run under the weak temperature gradient approximation, a parameterization of large-scale dynamics appropriate for the tropical atmosphere, is shown to have multiple stable equilibria.

A novel technique to infer ionic charge states of solar energetic particles [PDF]

, 2008
In some large solar energetic particle (SEP) events, the intensities of higher energy SEPs decay more rapidly than at lower energies. This energy dependence varies with particle species, as would be expected if the decay timescale depended on a rigidity ...

Variability of Tropical Cyclone Frequency Over the Western North Pacific in 2018–2020

Frontiers in Climate, 2021
In this study, we examine the tropical cyclone (TC) activity over the western North Pacific (WNP) in 2018–2020 and its relationship with planetary scale convection and circulation anomalies, which play an important role for TC genesis.

Improving precipitation simulations in CIESM through a new entrainment rate parameterization

npj Climate and Atmospheric Science
Entrainment rate parameterization is important for convection schemes but uncertain in climate models. A new deep convective entrainment rate (λ) parameterization (HL parameterization) is developed from aircraft observations and implemented into the ...
