Two-dimensional Moist Stratified Turbulence and the Emergence of Vertically Sheared Horizontal Flows

, 2011
Moist stratified turbulence is studied in a two-dimensional Boussinesq system influenced by condensation and evaporation. The problem is set in a periodic domain and employs simple evaporation and condensation schemes, wherein both the processes push ...

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

Microphysical Characteristics of a Squall Line Modulated by the Northeast China Cold Vortex Using Polarimetric Radar and Disdrometer Observations

Remote Sensing
Heavy precipitation in Northeast China is frequently modulated by the Northeast China Cold Vortex (NCCV), although the microphysical processes within squall lines under such conditions remain insufficiently understood. This study presents a comprehensive

Observations of the temporal variability in aerosol properties and their relationships to meteorology in the summer monsoonal South China Sea/East Sea: the scale-dependent role of monsoonal flows, the Madden–Julian Oscillation, tropical cyclones, squall lines and cold pools [PDF]

Atmospheric Chemistry and Physics, 2015
In a joint NRL/Manila Observatory mission, as part of the Seven SouthEast Asian Studies program (7-SEAS), a 2-week, late September 2011 research cruise in the northern Palawan archipelago was undertaken to observe the nature of southwest monsoonal ...

A Novel Approach for the Global Detection and Nowcasting of Deep Convection and Thunderstorms

Remote Sensing, 2022
Thunderstorms are among the most common and most dangerous meteorological hazards in the world. They cause lightning and can lead to strong wind gusts, squall lines, hail and heavy precipitation combined with flooding, and therefore pose a threat to ...

Characteristics of Intense Multi‐Day Wet Spells Over West Africa

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
The study reveals a significant increase in intense wet spells, particularly in KASS‐D, emphasising the value of dense rain‐gauge networks. Larger‐sized events have grown, while smaller ones declined, boosting 3‐day and 5‐day wet spells' contribution to annual rainfall, with the Guinea Coast showing the highest increase and the Sahel the lowest ...

The Improved NRL Tropical Cyclone Monitoring System with a Unified Microwave Brightness Temperature Calibration Scheme

Remote Sensing, 2014
The near real-time NRL global tropical cyclone (TC) monitoring system based on multiple satellite passive microwave (PMW) sensors is improved with a new inter-sensor calibration scheme to correct the biases caused by differences in these sensor’s high ...

Convective Organization in African Easterly Waves Observed During the NAMMA and CPEX‐CV Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Fundamental questions remain about where and when convection will occur within African easterly waves. In this study, we aim to better understand the dynamical processes that govern moist convective organization at the meso‐alpha scale in tropical easterly waves using NASA airborne field campaigns and satellite observations.

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
