Comparison of Characteristics and Extreme Gale Mechanisms of Two Strong Squall Lines in Zhejiang During Spring

应用气象学报
Two significant squall line events occurred in Zhejiang from afternoon until nightfall on 25 March and 2 April in 2024. In order to deepen the understanding of characteristics of the spring squall line and the mechanism of extreme wind, two processes are

Evaluating the Performance of a Convection-Permitting Model by Using Dual-Polarimetric Radar Parameters: Case Study of SoWMEX IOP8

Remote Sensing, 2020
In this study, a dual-polarimetric radar observation operator is established and modified for the Taiwan area for the purpose of model verification. A severe squall line case during the Southwest Monsoon Experiment Intensive Observing Period 8 (SoWMEX ...

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

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 ...

Mesoscale and microphysical processes leading to extreme hourly rainfall prior to the merger of two mesoscale convective systems in Central China

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
Short‐term extreme rainfall can be produced by the variation of low‐level warm moist airflow during mesoscale convective systems (MCSs) approaching another. The cold outflow of the rapidly moving MCS intensifies the warm moist airflow in front, enhancing the convergence and ascending motion in the quasi‐stationary MCS.

Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 777, April 2026 Part B.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...
