Surface layer characteristics of thunderstorm outflow [PDF]

open access: yes, 1997
The objective of this study is to define the turbulent characteristics of thunderstorm outflow winds in the surface layer. Thunderstorms are one of the most common types of severe weather, and the climatological record for many stations shows many ...

Impact of Convective Intensity on Mixed‐Phase Evolution and Upper Positive Charge Region Formation in an Isolated Convective Cloud

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning initiation depends on the charge separation within the mixed‐phase areas of convective clouds, where graupel, ice, and supercooled water interact. However, the specific mixed‐phase structures that enhance charge separation remain unclear.

Electrical thunderstorm nowcasting using

open access: yes, 2008
This paper presents a study developed at SIMEPAR (Paran state weather service) using lightning data for electrical thunderstorm nowcasting. Thunderstorm electrical data collected at SIMEPAR such as lightning location, time of occurrence, current ...

The Role of Lightning in Atmospheric Chemistry

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Compound weather systems of cyclones, fronts and thunderstorms in global reanalysis

open access: yesEnvironmental Research Letters
Many studies have examined the climatology of individual types of impactful weather systems such as cyclones, fronts and thunderstorms, with some recent studies also considering compound weather systems where more than one type occur at the same time and

Convection‐Permitting Projections of Low‐Level Jets and Mesoscale Convective Systems in South America

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Anthropogenic warming is expected to substantially modify the hydroclimate of South America, a region in which low‐level jets (LLJs) and mesoscale convective systems (MCSs) are key components of moisture transport and precipitation. However, the responses of these systems to future climate change, including the relative roles of thermodynamic ...

An Integrated Process‐Based Approach for Interpreting Precipitation Isotopes Using North‐Central Texas as a Testbed

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The isotopic composition of precipitation reflects the combined influences of moisture sources, rainout history, and convective intensity, but the relative importance of these controls varies among regions and remains poorly understood in continental settings.
