The objective of the session is to connect different communities in touch with "extreme clouds" (convective and volcanic clouds) and to promote discussions between scientists on future developments, in understanding, monitoring and forecasting the extreme clouds, studying their impact and to extend the discussion with the end-users for improving air safety.

This session solicits the latest studies from the spectrum of:
- detection, monitoring and modeling of extreme clouds,

- understanding the extreme clouds structure,

- forecasting and nowcasting extreme weather events,
- understanding the impact of extreme clouds on air traffic management,
- proposal of new products or services focused on the end-users prospective,
- forecasting tools to support air traffic management improving the limits of the present science and new products/tools providing better services to the end-users,
- extreme clouds remote sensing with novel techniques and new sensors,
- novel techniques to detect overshooting.
