Topic: climate variability

The annual meeting brings together research on weather, climate, hydrology, oceans and related environmental systems. Its conferences and symposia cover atmospheric chemistry, climate variability, observing systems, satellite measurements, modelling and communication of scientific information. The 2027 theme emphasizes education and the use of Earth-system knowledge by people and communities. Scientific sessions, professional exchanges and short courses are offered alongside in-person and online participation.

Atmospheric gravity waves arise from processes including flow over mountains, moist convection and geostrophic imbalance. They connect atmospheric layers, influence tropospheric jet streams and play a major dynamical role in the stratosphere and mesosphere. Yet much of their spectrum is unresolved by typical climate models, and observations provide limited constraints. Aditi Sheshadri presents research combining observations, high-resolution simulations and data-informed methods to understand their effects on climate variability and improve their representation in global models.
