Led by Dietmar Dommenget

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 more than CLEX 100 subscribers. To join our list, please contact Andrea Taschetto ( Email: a.taschetto@unsw.edu.au ). Due to a large number of members, we have decided to cycle the meetings through four themes:

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 the theme leaders above.
