SUPERPARAMETERIZATION OF LOW-TEMPERATURE VIBRATIONAL DATA FOR LANTHANIDE HEXAHALIDE ANIONS

Spectrochimica Acta Part A: Molecular Spectroscopy, 1994
A complete dataset is presented for the modes of vibration of LnCl63- in CsNaLnCl6, from low temperature Raman and vibronic spectroscopy. Conventional force constant calculations with this dataset are unsatisfactory since, although the datafits are quite

Reproducibility of Equatorial Kelvin Waves in a Superparameterized MIROC: 1. Implementation and Verification of Blockwise‐Coupled SP‐MIROC

Journal of Advances in Modeling Earth Systems
The potential scope of superparameterization (SP) was extended to higher resolutions of the global climate model (GCM) component by devising a technique called blockwise coupling.

Reproducibility of Equatorial Kelvin Waves in a Super‐Parameterized MIROC: 2. Linear Stability Analysis of In‐Model Kelvin Waves

Journal of Advances in Modeling Earth Systems
While low‐resolution climate models at present struggle to appropriately simulate convectively coupled large‐scale atmospheric disturbances such as equatorial Kelvin waves (EKWs), superparameterization helps better reproduce such phenomena.

Predictive Proxies of Present and Future Lightning in a Superparameterized Model [PDF]

Journal of Geophysical Research: Atmospheres, 2021
AbstractA superparameterized climate model is used to assess the global performance of several previously proposed proxies for lightning. In particular, predictors incorporating hydrometeor (ice, graupel) profiles and convective vertical velocities are compared to observations, then used to estimate changes in flash rates with global warming.

Efficient stochastic superparameterization for geophysical turbulence [PDF]

Proceedings of the National Academy of Sciences, 2013
Efficient computation of geophysical turbulence, such as occurs in the atmosphere and ocean, is a formidable challenge for the following reasons: the complex combination of waves, jets, and vortices; significant energetic backscatter from unresolved small scales to resolved large scales; a lack of dynamical scale separation between large ...

Potential Predictability of the Madden‐Julian Oscillation in a Superparameterized Model

Geophysical Research Letters, 2023
The Madden‐Julian Oscillation (MJO) is a promising target for improving sub‐seasonal weather forecasts. Current forecast models struggle to simulate the MJO due to imperfect convective parameterizations and mean state biases, degrading their forecast ...

Effects of the Horizontal Scales of the Cloud‐Resolving Model on Tropical Cyclones in the Superparameterized Community Atmosphere Model

Earth and Space Science, 2023
In this study, the Superparameterized Community Atmosphere Model (SPCAM) is used to simulate tropical cyclones (TCs) using the hindcast approach. Three hindcast experiments are conducted with 32‐km (D32), 128‐km (D128), and 1,024‐km (D1024) horizontal ...

Load‐Balancing Intense Physics Calculations to Embed Regionalized High‐Resolution Cloud Resolving Models in the E3SM and CESM Climate Models

Journal of Advances in Modeling Earth Systems, 2022
We design a new strategy to load‐balance high‐intensity sub‐grid atmospheric physics calculations restricted to a small fraction of a global climate simulation's domain.

Microphysical Sensitivity of Superparameterized Precipitation Extremes in the Contiguous United States Due to Feedbacks on Large‐Scale Circulation

Earth and Space Science, 2020
Superparameterized (SP) global climate models have been shown to better simulate various features of precipitation relative to conventional models, including its diurnal cycle as well as its extremes.

Understanding the Response of Tropical Ascent to Warming Using an Energy Balance Framework

Journal of Advances in Modeling Earth Systems, 2020
Previous work has established that warming is associated with an increase in dry static stability, a weakening of the tropical circulation, and a decrease in the convective mass flux.
