Tropical Cirrus in Global Storm‐Resolving Models: 1. Role of Deep Convection
Earth and Space Science, 2022 Pervasive cirrus clouds in the upper troposphere and tropical tropopause layer (TTL) influence the climate by altering the top‐of‐atmosphere radiation balance and stratospheric water vapor budget.

Earth and Space Science, 2022 Cirrus clouds of various thicknesses and radiative characteristics extend over much of the tropics, especially around deep convection. They are difficult to observe due to their high altitude and sometimes small optical depths. They are also difficult to

Aircraft observations of gravity wave activity and turbulence in the tropical tropopause layer: prevalence, influence on cirrus clouds, and comparison with global storm-resolving models [PDF]
Atmospheric Chemistry and Physics, 2023 The tropical tropopause layer (TTL) is a sea of vertical motions. Convectively generated gravity waves create vertical winds on scales of a few to thousands of kilometers as they propagate in a stable atmosphere.

Journal of Advances in Modeling Earth Systems, 2021 Reducing the model spread in free‐tropospheric relative humidity (RH) and its response to warming is a crucial step toward reducing the uncertainty in clear‐sky climate sensitivity, a step that is hoped to be taken with recently developed global storm ...

Comparing storm resolving models and climates via unsupervised machine learning [PDF]
Scientific Reports, 2023 Global storm-resolving models (GSRMs) have gained widespread interest because of the unprecedented detail with which they resolve the global climate. However, it remains difficult to quantify objective differences in how GSRMs resolve complex atmospheric

A protocol and analysis of year-long simulations of global storm-resolving models and beyond
Progress in Earth and Planetary ScienceWe propose a protocol to evaluate and analyze year-long simulations of global storm-resolving models (GSRMs). The proposed protocol complements an earlier 40-day simulation protocol under the DYAMOND (DYnamics of the Atmospheric general circulation ...

A causal intercomparison framework unravels precipitation drivers in Global Storm-Resolving Models
npj Climate and Atmospheric ScienceCorrectly representing convective precipitation remains a long-standing problem in climate models, due to its highly parameterized nature and unclear role of drivers interacting over a wide range of spatial scales.

On the Realism of Tropical Cyclone Intensification in Global Storm‐Resolving Climate Models
Geophysical Research LettersThe physical processes governing a tropical cyclone's lifecycle are largely understood, but key processes occur at scales below those resolved by global climate models. Increased resolution may help simulate realistic tropical cyclone intensification. We
