Led by Dietmar Dommenget and Andrea Taschetto

The CLEX Tropical Variability group meets every 2 – 3 months via videoconference to share research on atmospheric sciences, physical oceanography and climate from subseasonal to multidecadal timescales and beyond.

The meetings occur on the second Tuesday of the month at 10am as a part of the CLEX Weather and Climate Interactions (WACI) meetings. See schedule below. Meeting announcements are sent to the WACI email list.

Whenever possible we will organise the meetings around topics that feed into the overall aims of CLEX Climate and Weather Interactions and may contribute to other CLEX research programs, such as Attribution and Risk and Drought.

We are aiming for one or two speakers each month. Talks are flexible and should allow time for discussions and feedback afterwards.

We welcome volunteers to talk in the meetings. If you want to give a talk at the Tropical Variability meeting, please contact Andrea Taschetto (Email: a.taschetto@unsw.edu.au ), Dietmar Dommenget (dietmar.dommenget@monash.edu) or Malcolm King (malcolm.king@monash.edu). In particular, we would like to encourage students to present in those meetings. These are informal meetings, you do not need to have a full publication when you present. In fact, these meetings should work as a way to receive feedback before you publish or present to a larger meeting. So, please come with your current study, a few plots, and show to the group.
