The Predictability of the Southern England 23 October 2022 Severe Downbursts

open access: yesAtmospheric Science Letters
Accurate prediction of damaging straight‐line wind events from convective storms relies heavily on storm morphology and nowcasting. Utilising the Microburst Wind Potential Index in ensemble forecasts we examine the predictability of its different ...

Vagus Nerve Stimulation in Movement Disorders, from Principles to a Systematic Review of Evidence. [PDF]

open access: yesMov Disord
Abstract Background The vagus nerve (VN), the principal component of the parasympathetic branch of the autonomic nervous system (ANS), mediates bidirec communication between the central nervous system (CNS) and peripheral organs. Vagus nerve stimulation (VNS), delivered through invasive (iVNS) or non‐invasive (transcutaneous cervical [tcVNS] and ...

Relativistic Microburst Scale Size Induced by a Single Point‐Source Chorus Element

open access: yesGeophysical Research Letters, 2022
Relativistic microbursts are impulsive, sub‐second precipitation bursts of relativistic electrons. They are one of the main loss mechanisms of outer radiation belt electrons, and are driven by chorus waves.

The Repetition Period of MeV Electron Microbursts as Measured by SAMPEX/HILT

open access: yesGeophysical Research Letters, 2023
Here we examine properties of MeV electron microbursts to better understand their generation mechanisms. Using 15 years of data from Solar, Anomalous, Magnetospheric Particles Explorer/Heavy Ion Large Telescope, >1 MeV microburst repetition periods (time

Convective Density Current Circulations That Modulated Meso-γ Surface Winds near the Yarnell Hill Fire

open access: yesFire, 2023
On 30 June 2013, 19 Granite Mountain Hotshots firefighters were killed fighting a wildfire near Yarnell in the mountains of Central Arizona. They succumbed when the wildfire, driven by erratic winds, blocked their escape route and overran their location.

Observation of an Electron Microburst With an Inverse Time‐Of‐Flight Energy Dispersion

open access: yesGeophysical Research Letters, 2023
Interactions between whistler mode chorus waves and electrons are a dominant mechanism for particle acceleration and loss in the outer radiation belt.

Large-Eddy Simulation of a microburst [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
The three-dimensional structure and evolution of an isolated and stationary microburst are simulated using a time-dependent, high resolution Large-Eddy-Simulation (LES) model.

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

Flight Dynamic Characteristics of Wide-Body Aircraft with Wind Gust and Turbulence

open access: yesFluids, 2023
In this research, a wide-body aircraft was analyzed with critical monitoring of its states, a function of several control inputs (wind gust, turbulence, and microburst).
