Welcome to the 4th Gravity Wave Workshop in Prague, Czech Republic 19–21 AUG 2024

Unresolved processes in climate models present a major source of uncertainty in future climate projections. This workshop will get together experts on GW dynamics, observations, modelling and climate effects to discuss recent developments and frame future research avenues.

Date

19 – 21.8. 2024

Agenda

Presenters shall allocate around 1/3 of their slot for the open discussion.

Abstract submission

CLOSED

As there is no registration fee and a limited capacity of the venue (around 80 participants), we cannot guarantee to accept each submission.
