Spatial Patterns of Shallow Clouds: Challenging the Concept of Defined Regimes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Tropical shallow clouds are a major source of uncertainty in Earth's climate sensitivity, especially through their spatial arrangement, which global climate models do not represent. Efforts to understand their organization have partly relied on classifying observed scenes, identifying four patterns as archetypal regimes.

Can Terrain Induce Moist Absolutely Unstable Layers and Enhance Extreme Rainfall?

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Extreme rainfall events in Taiwan pose significant forecasting challenges due to complex multiscale interactions. Although orographic lifting is known to trigger convection, its role in modifying atmospheric stability, specifically through the formation of moist absolutely unstable layers (MAULs), remains underexplored. This study presents the

Assessing the Performance of the WRF Model in Simulating Squall Line Processes over the South African Highveld

Atmosphere
Squall lines are some of the most common types of mesoscale cloud systems in tropical and subtropical regions. Thunderstorms associated with these systems are among the major causes of weather-related disasters and socio-economic losses in many regions ...

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

A radar study of a squall-line at Agartala

MAUSAM, 1963
The results of the study of a typical squall-line thunderstorm of the pre-monsoon season from the time of its formation to its decay, with the aid of the storm-warning radar at Agartala airport are presented in this paper.

A short review of numerical cloud-resolving models

Tellus: Series A, Dynamic Meteorology and Oceanography, 2017
A cloud-resolving model (CRM) allows performing numerical simulations of convective clouds, such as shallow cumulus and stratocumulus, or storms and squall-lines with a resolution on the order of a few tens of metres to a few kilometres over a limited ...

External Drivers and Mesoscale Self‐Organization of Shallow Cold Pools in the Trade‐Wind Regime

Journal of Advances in Modeling Earth Systems
Recent observations of the trade‐wind regions highlight the covariability between cold‐pool properties and mesoscale cloud organization. Given the covariability of organization with cloud cover and albedo, this suggests a potential impact of cold pools ...

Dynamics of a developing squall line

Meteorologische Zeitschrift, 1994
Four kinds of severe, mesoscale convective-line development have been identified. One type, back-building, involves the periodic appearance of a new cell upstream of the existing line. Ultimately this new cell merges with the line, as new cells continue to form in the upstream direction.

Explicit Prediction of Continental Convection in a Skillful Variable‐Resolution Global Model

Journal of Advances in Modeling Earth Systems, 2019
We present a new global‐to‐regional model, cfvGFS, able to explicitly (without parameterization) represent convection over part of the Earth. This model couples the Geophysical Fluid Dynamics Laboratory Finite‐Volume Cubed‐Sphere Dynamical Core (FV3) to ...
