Description:

Spatio-temporal variations in the ionosphere-thermosphere (IT) system are well-known manifestations of variability in space weather conditions. However, in recent times, different lower atmosphere processes and terrestrial weather have also been shown to produce variabilities that can directly or indirectly impact the upper atmosphere and ionosphere on a wide range of spatial and temporal scales, and couple with the effects driven by space weather. The focus of this session is to discuss this connection between space weather and terrestrial weather. Relevant topics include but are not limited to planetary waves and tides, acoustic and gravity waves, multi-layer observation and/or model-based studies of the different lower atmospheric contributions to the dynamics and variability of the near-earth space environment.
