Led by Dietmar Dommenget, Andrea Taschetto, Chen Li, Christine Chung, Claire Vincent & Giovanni Liguori.

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

The meetings occur every second Tuesday at 10am. Meeting reminders are sent to the group email list (clex-variability-tropical@lists.unsw.edu.au) on the Thursday and Monday before the meeting.

We have 6 leaders for the tropical variability meetings:

Each leader is responsible for organising for one month. Whenever possible we will organise the meetings around topics that feed into the overall aims of the CLEX Variability Program and may contribute to other CLEX research programs, such as rainfall extremes and drought.

We are aiming for one or two speakers each month. Talks will be around 15 to 20min to allow time for discussions after.

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 ) –  or one of the leaders above. 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.
