Contribution of personal weather stations to the observation of deep-convection features near the ground [PDF]

Natural Hazards and Earth System Sciences, 2020
The lack of observations near the surface is often cited as a limiting factor in the observation and prediction of deep convection. Recently, networks of personal weather stations (PWSs) measuring pressure, temperature and humidity in near-real time have

On the Dependence of Squall-Line Characteristics on Surface Conditions

Journal of the Atmospheric Sciences, 2017
Abstract The influence of surface conditions in the form of changing surface temperatures on fully developed mesoscale convective systems (MCSs) is investigated using a cloud-system-resolving setup of the Icosahedral Nonhydrostatic (ICON) model (1-km grid spacing). The simulated MCSs take the form of squall lines with trailing stratiform

Unmothered at Work: Organizational Silence Around Reproductive Loss

Gender, Work &Organization, EarlyView.
ABSTRACT An identity transition refers to changes in self‐concept that can result from professional or personal shifts. Although organizations increasingly support institutionally legible and culturally normative nonwork transitions, others remain professionally stigmatized or culturally unspeakable.

Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Buoyancy Flux and Its Environmental Modulation in the Vertical Development of Shallow Cumulus in the Central Amazon

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract This study investigates the vertical development of shallow cumulus (ShCu) clouds in the Central Amazon (CAMZ) by combining large‐eddy simulations (LES) with observational data from the GoAmazon2014/5 campaign. Analyses of turbulent kinetic energy budgets, updraft mass flux, moisture flux, and surface fluxes across cloud sizes indicate that ...

An Analysis of Hurricane Eyewall Ice Using a Novel Lagrangian Trajectory and Growth Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Ice crystals in tropical cyclones (TCs) remain infrequently observed and difficult to model using Eulerian microphysics parameterizations. To better understand TC eyewall ice crystal processes, the Ice Crystal Trajectory Growth (ICTG) model, previously applied to an idealized squall line, was used to simulate Lagrangian ice crystal ...

Analysis of Dual-Polarimetric Radar Variables and Quantitative Precipitation Estimators for Landfall Typhoons and Squall Lines Based on Disdrometer Data in Southern China

Atmosphere, 2019
Typhoon rainstorms often cause disasters in southern China. Quantitative precipitation estimation (QPE) with the use of polarimetric radar can improve the accuracy of precipitation estimation and enhance typhoon defense ability.

Impact of Moist Thermodynamic Formulations on Climatological Temperature Fields in a Global Cloud‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract This study investigates how climatological temperature fields in simulations are influenced by the choice of moist thermodynamic formulations. Two formulations were compared: one developed to ensure internal thermodynamic consistency, and a simpler approximation similar to those commonly used in meteorological and climate models.
