Quantifying finite range plasma turbulence [PDF]

open access: yes
Turbulence is a highly non-linear process ubiquitous in Nature. The nonlinearity is responsible for the coupling of many degrees of freedom leading to an unpredictable dynamical evolution of a turbulent system.

The Role of Terrain and Convection on Microfront Formation Leading to Severe Low-Level Turbulence

open access: yes, 2003
Two low-level convectively-induced turbulence (CIT) events east of the Appalachian Mountains are investigated utilizing observations, satellite, radar, and numerical simulations. Both events had an inordinate amount of low-level turbulence reported, but

Design Spectra for Evaluating the Dynamic Response of Buildings Under Thunderstorm Downbursts

open access: yesBuildings
This paper presents a spectral method to determine the effect of thunderstorm downbursts on structures. The method integrates the dynamic response of single oscillators subject to input accelerations induced by wind, based on classical earthquake ...

Fire‐Atmosphere Coupling Starts Upwind: Selective Redistribution of Turbulence at the Fire‐Induced Rear Inflow

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Wildfires alter local atmospheric conditions, yet the spatial extent and frequency‐dependent characteristics of fire‐induced inflow perturbations remain largely unquantified. This study applies Multivariate Empirical Mode Decomposition (MEMD) to analyze high‐frequency horizontal wind speed data from a tower positioned at varying distances (∼80–

Adjustment of a turbulent boundary layer to a 'canopy' of roughness elements [PDF]

open access: yes, 2003
A model is developed for the adjustment of the spatially averaged time-mean flow of a deep turbulent boundary layer over small roughness elements to a canopy of larger three-dimensional roughness elements.

A Compensated Structure‐Function Approach to Measuring TKE Dissipation in the Atmospheric Boundary Layer

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Despite the importance of turbulence measurements to atmospheric dynamics and modeling, developing objective, accurate schemes to estimate TKE dissipation ε from velocity time‐series has proven elusive. Objective schemes can be automated, as needed for large data sets generated by today's field programs.

GAM-STTD: a spatiotemporal tropospheric delay correction model for time-series InSAR in complex mountainous regions

open access: yesInternational Journal of Digital Earth
Tropospheric delay remains a critical error source in time-series interferometric synthetic aperture radar (TS-InSAR), particularly in mountainous and plateau regions where seasonal stratification and stochastic turbulence coexist.

Meteorological and Emission Drivers of Compound Heat and Ozone Pollution Episodes in Oklahoma City During Periods Influenced by Atlantic Tropical Cyclones

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Compound heat and ozone (O3) pollution events are widespread and pose significant health risks in urban areas. In the Southern Great Plains (SGP), where heat waves are becoming more frequent and intense, these compound events represent a growing environmental and public health concern, underscoring the need for improved process‐based ...

Evaluation of Riming in the P3‐2ice Microphysics Scheme: A Case Study of Cold‐Air Outbreak Snowfall in Eastern China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using the multi‐frequency radar suite, ground‐based observations, and the Weather Research and Forecasting (WRF) model with the Predicted Particle Properties microphysics scheme with the version of two‐ice category (P3‐2ice), we study the characteristics of a cold‐air outbreak (CAO) snowfall event on 6–7 December 2024.
