Poster (Non-Student) / Affiche (Non-étudiant(e))

Travelling ionospheric disturbances are plasma density fluctuations usually driven by atmospheric gravity waves generated by sources in the upper or lower atmosphere. Eastward to southeastward propagating medium-scale traveling ionospheric disturbances (MSTIDs) are commonly observed at mid latitudes over Europe by the GNSS total electron content (TEC) mapping technique and the multipoint and...

Poster not-in-competition (Graduate Student) / Affiche non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The RADICALS Space mission will consist of a satellite with a suite of detectors designed to study the effects of incoming space radiation on the atmosphere where one of the goals is to measure the flux of precipitating electrons entering the upper atmosphere. This quantitative data will allow better modeling of the physical processes that couple the magnetosphere, ionosphere, and...

369. (POS-9) Occurrence of tornado outbreaks in the context of solar wind coupling to magnetosphere-ionosphere-atmosphere

Poster (Non-Student) / Affiche (Non-étudiant(e))

The National Oceanic and Atmospheric Administration National Weather Service database of tornadoes provided by the Storm Prediction Center is used to investigate the occurrence of tornado outbreaks in the United States from 1963 to 2023 in the context of solar wind that impacts the Earth’s magnetosphere. The superposed epoch analysis of daily occurrence of tornadoes reveals a peak in the...
