The Fractal Nature of Clouds in Global Storm‐Resolving Models [PDF]

Geophysical Research Letters, 2021
AbstractClouds in observations are fractals: they show self‐similarity across scales ranging from 1 to 1,000 km. This includes individual storms and large‐scale cloud structures typical of organized convection. It is not known whether global storm‐resolving models reproduce the observed fractal scaling laws for clouds and organized convection.

Global Cloud-Resolving Models [PDF]

Current Climate Change Reports, 2019
Global cloud-resolving models (GCRMs) are a new type of atmospheric model which resolve nonhydrostatic accelerations globally with kilometer-scale resolution. This review explains what distinguishes GCRMs from other types of models, the problems they solve, and the questions their more commonplace use is raising.

The impact of aerosols on cloud and precipitation processes: cloud-resolving model simulations [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
• For all three cases, higher CCN produces smaller cloud droplets and a narrower spectrum. Dirty conditions delay rain formation, increase latent heat release above the freezing level, and enhance vertical velocities at higher altitude for all cases. Stronger updrafts, deeper mixed-phase regions, and more ice particles are simulated with higher CCN in ...

Comparison of the simulated outcomes of aerosol–cloud interaction by a meteorological model with and without an interactive chemistry module

Scientific Reports, 2023
With the general rise of computational capacities and the continued efforts to improve computational efficiencies, more and more studies have been utilizing state-of-the-art atmospheric models that enable cloud-resolving simulations over a global domain.

Intensification of Precipitation Extremes with Warming in a Cloud-Resolving Model [PDF]

Journal of Climate, 2011
Abstract A cloud-resolving model is used to investigate the effect of warming on high percentiles of precipitation (precipitation extremes) in the idealized setting of radiative-convective equilibrium. While this idealized setting does not allow for several factors that influence precipitation in the tropics, it does allow for an ...

Statistical properties of cloud lifecycles in cloud-resolving models [PDF]

Atmospheric Chemistry and Physics, 2008
Abstract. A new technique is described for the analysis of cloud-resolving model simulations, which allows one to investigate the statistics of the lifecycles of cumulus clouds. Clouds are tracked from timestep to timestep within the model run. This allows for a very simple method of tracking, but one which is both comprehensive and robust. An approach

Modeling Land‐Atmosphere Coupling at Cloud‐Resolving Scale Within the Multiple Atmosphere Multiple Land (MAML) Framework in SP‐E3SM

Journal of Advances in Modeling Earth Systems, 2023
Representing subgrid variabilities of land surface processes and their upscaled effects is crucial for global climate modeling. Here, we implement a multiple atmosphere multiple land (MAML) framework in the superparamaterized version of E3SM (SP‐E3SM) to

What Controls the Mesoscale Variations in Water Isotopic Composition Within Tropical Cyclones and Squall Lines? Cloud Resolving Model Simulations in Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems, 2023
Water isotopes are tracers of convective processes and are often used as proxies for past precipitation. These applications require a better understanding of the impact of convective processes on the isotopic composition of water vapor and precipitation.

Cloud Resolving Modeling of Contrail Evolution

, 2012
Contrails are ice clouds that form behind aircraft. As a result of burning kerosene in the engines, water vapor is emitted that rapidly freezes and forms ice crystals. If the atmosphere is sufficiently moist and cold, these contrails expand and persist for many hours.

Impact of different definitions of clear-sky flux on the determination of longwave cloud radiative forcing: NICAM simulation results [PDF]

Atmospheric Chemistry and Physics, 2010
Using one month of the cloud-resolving Nonhydrostatic Icosahedral Atmospheric Model (NICAM) simulations, we examined the impact of different definitions of clear-sky flux on the determination of longwave cloud radiative forcing (CRF).
