Discussion Meeting
Thierry Dauxois, Sylvain Joubaud, Manikandan Mathur, Philippe Odier and Anubhab Roy
15 March 2021 to 19 March 2021
Ramanujan Lecture Hall, ICTS Bangalore

The program is postponed. Revised dates will be announced soon.



Waves are ubiquitous in natural fluid systems like the Earth's ocean, planetary atmosphere, and the interior of stars and planets. Stratification (owing to spatial variations of temperature, salinity, gravity or magnetic field) and/or Coriolis effects (owing to the rotation of planets & stars) represent key physical ingredients of wave generation, propagation and dissipation in many of these large-scale systems. Together with the significant amounts of energy input into them, the ability of waves to transport energy and momentum (and maybe mass too) through large spatial extents has significant implications for (i) global flow features like oceanic or atmospheric circulation, mean temperature distribution in planets/stars etc., (ii) the overall energy budget, and (iii) biological activity in the ocean. Furthermore, it is now widely recognized that wave dissipation mechanisms (and the resulting generation of heat and mixing) have to be accurately parameterized in global scale numerical models like the Earth's climate model. Finally, an understanding of various small and large-scale wave phenomena in idealized models of complex large-scale systems like the ocean paves way for improved observation, understanding and prediction of the evolving global climate.

The proposed program would cover topics pertaining to the generation, propagation and dissipation of waves in stratified and rotating fluids, with applications focused on (but not restricted to) the Earth's oceans. Related applications to the Earth's atmosphere, and other planetary/astrophysical systems will also be encouraged to foster exchange of ideas.

This meeting would bring together physicists, mathematicians, fluid dynamicists, and oceanographers with three main objectives:

  1. to deliver pedagogical lectures on the aforementioned topics
  2. to identify important problems that the overall community could focus on in the next decade
  3. to exchange ideas and tools between the various research communities
