Observation of Tropospheric Deep Convection in Mid-Latitudes with Potential Impact up to Ionospheric Heights

Our case study investigates the coincidental occurrence of intense tropospheric convection and upper atmospheric variability.It focuses on the generation of gravity waves (GWs) at tropospheric heights and their potential impact on the ionosphere.Our analysis presents an organised mesoscale convective system (MCS) associated with a derecho event and air-mass severe thunderstorms with supercells occurring.In both cases, sporadic ionospheric E layer was recorded.A significant reduction in electron density, which was expected after the passage of an extensive MCS, was also observed in the case of very intensive but spatially limited supercell thunderstorms.
