Cloud clusters cover a wide range of scales: from the turbulent cloud cluster that we observe in the sky with our naked eyes to the gigantic organized cloud bands such as Monsoons, The Inter-Tropical Convergence Zone (ITCZ), Cyclones,  the Madden-Julian oscillation (MJO) etc. that satellites observe. On these different scales clouds either aggregate through their own local cloud-circulation feedbacks or sometimes they are seen to ride on top of vortices linked to waves and instabilities. Although the monsoon dynamics has been studied for a long time, how monsoon convection organizes on a variety of time-scales is an unresolved enigma. This program will be organized around this unresolved scientific direction.

Topics covered will include:

  1. Geophysical fluid dynamics of moist flows: Intro to GFD, Shallow Water equations, Two-layer models, Moist dynamics on equatorial beta plane, Waves and Instabilities, Idealised modeling, parameterisation of precipitation in GFD models.
  2. Physics of convective organization: Basics of convection, radiation, Convective aggregation, Idealised modeling, Observations of convective organization, Using simulations to understand physics of convection.
  3. Understanding variability in monsoon convection: Meteorology of monsoon convection, Microphysics, Structure of monsoon convection, Cloud resolving models, Convective parameterisation in weather and climate models, Data-driven approaches to monsoon variability, Understanding forecasting methods, Limitations of current methods

Accommodation will be provided for outstation participants at our on campus guest house.


Students and PhD holders working on the following 3 themes are eligible to apply. All participants are required to present at least a poster of their work.

  1. Geophysical fluid dynamics of moist flows
  2. Physics of convective organization
  3.  Understanding variability in monsoon convection 

ICTS is committed to building an environment that is inclusive, non discriminatory and welcoming of diverse individuals. We especially encourage the participation of women and other under-represented groups.
