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.

Parameterization of Entrainment Rate for Cumulus Clouds with WRF Simulation

Atmosphere, 2023
By using Weather Research and Forecasting Model (WRF) to simulate a southwest vortex precipitation process, this work studies the correlations between entrainment rate (λ) and dynamical parameters in the cloud and further fit λ. We relate the probability

Parameterizing deep convection using the assumed probability density function method [PDF]

Geoscientific Model Development, 2015
Due to their coarse horizontal resolution, present-day climate models must parameterize deep convection. This paper presents single-column simulations of deep convection using a probability density function (PDF) parameterization.

Model Sensitive in Numerical of the Formation of Typhoon Robyn (1993)

Terrestrial, Atmospheric and Oceanic Sciences, 2006
The PSU-NCAR mesoscale model MM5 with an 81-km (27-km) resolution coarse (fine) grid is used to simulate the formation of Typhoon Robyn (1993) in the western North Pacific. This study examines the roles of mesoscale convective system (MCS) during Robyn’s

Sensitivity of Tropical Cyclone Idai Simulations to Cumulus Parametrization Schemes

Atmosphere, 2021
Weather simulations are sensitive to subgrid processes that are parameterized in numerical weather prediction (NWP) models. In this study, we investigated the response of tropical cyclone Idai simulations to different cumulus parameterization schemes ...

A new approach to the cumulus parameterization issue [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 2003
Can the superensemble methodology provide improved precipitation forecasts by combining existing physical parameterizations? We recently addressed this question in the context of Numerical Weather Prediction (NWP).We feel, however, that the information provided here may be useful for seasonal climate modeling as well.

Atmospheric transport and chemistry of trace gases in LMDz5B: evaluation and implications for inverse modelling [PDF]

, 2014
Representation of atmospheric transport is a major source of error in the estimation of greenhouse gas sources and sinks by inverse modelling. Here we assess the impact on trace gas mole fractions of the new physical parameterizations recently ...
