Hallett‐Mossop Rime Splintering Dims Cumulus Clouds Over the Southern Ocean: New Insight From Nudged Global Storm‐Resolving Simulations

AGU Advances, 2022
In clouds containing both liquid and ice with temperatures between −3°C and −8°C, liquid droplets collide with large ice crystals, freeze, and shatter, producing a plethora of small ice splinters.

Kilometer-scale global warming simulations and active sensors reveal changes in tropical deep convection

npj Climate and Atmospheric Science, 2023
Changes in tropical deep convection with global warming are a leading source of uncertainty for future climate projections. A comparison of the responses of active sensor measurements of cloud ice to interannual variability and next-generation global ...

Advancements and continued challenges in observations and global modelling of atmospheric ice mass [PDF]

Atmospheric Chemistry and Physics
We assess the current status of atmospheric ice mass estimates by first critically comparing satellite-based datasets, then examining global circulation and global storm-resolving models. The analysis focuses on the frozen water path, which offers a more

Evaluation of Global Climate and Storm-Resolving Model Representations of Mixed-Phase Clouds and Their Hemispheric Contrasts

Atmosphere
Mixed-phase clouds, in which liquid droplets and ice crystals coexist at temperatures between −38 °C and 0 °C, play a critical role in Earth’s radiation budget.

The Sensitivity of Moisture Flux Partitioning in the Cold‐Point Tropopause to External Forcing

Geophysical Research Letters, 2023
The dryness of the stratosphere is the result of air entering through the cold tropical tropopause layer (TTL). However, our understanding of the moisture flux partitioning into water vapor and frozen hydrometeors is incomplete.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Tropical Convection Overshoots the Cold Point Tropopause Nearly as Often Over Warm Oceans as Over Land

Geophysical Research Letters, 2023
Tropical convection that overshoots the cold point tropopause can impact the climate by directly influencing water vapor, temperatures, and thin cirrus in the upper troposphere‐lower stratosphere (UTLS) region.

Impact of Warmer Sea Surface Temperature on the Global Pattern of Intense Convection: Insights From a Global Storm Resolving Model

Geophysical Research Letters, 2022
Intense convection (updrafts exceeding 10 m s−1) plays an essential role in severe weather and Earth's energy balance. Despite its importance, how the global pattern of intense convection changes in response to warmed climates remains unclear, as ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Impact of Domain Size on Tropical Precipitation Within Explicit Convection Simulations

Geophysical Research Letters, 2023
We investigate the sensitivity of modeled tropical precipitation accumulation, intensity and structures to the extent of convection‐permitting limited area model (LAM) domain size.
