Title:  Advancing Understanding of Monsoons: Two Distinct but Complementary Approaches

Abstract:  Monsoons play a starring role in Earth’s general circulation and in the livelihoods of billions of people. Accurate predictions of monsoon rainfall variations from intraseasonal to centennial timescales, both natural and human-induced, would be of tremendous value but have proved vexing. This isn’t shocking, given that our conceptual understanding of some of the most basic characteristics of monsoonal overturning circulations generally and of real-world systems such as the Indian monsoon remains incomplete. In this talk, I describe two approaches, one highly theoretical and the other highly empirical, I have employed in recent years to attack this knowledge gap. The first combines analytical theory and simulations in idealized climate models to develop a new theory for the extent of the ascending and descending branches of zonally averaged monsoonal circulations (i.e. the solsticial Hadley cell). The second uses gauge-based rainfall data in India to delineate the mechanisms linking interannual variability in Indian summer monsoon rainfall within sub-regions of the subcontinent.

Time: 3:30 PM, Thursday, Feb. 18, 2021

Zoom Link:  https://fsu.zoom.us/j/92495409312?pwd=VklzSHdVY0JOUzdDODg4TzJGbnhkdz09

It is noted that the pre-seminar session, "Meeting the Speaker," will start at 3:00 PM with the same zoom link.  A post-seminar student only session will starts immediately after seminar. Look forward to seeing you then.
