Shallow and Deep convection by Geet George

Program: Moist convective dynamics of Monsoons
ORGANIZERS: Gilles Bellon (CNRM Toulouse, France), Vishal Dixit (IIT Bombay, India), Bishakhdatta Gayen (IISc, India) and Jim Thomas (ICTS-TIFR & TIFR-CAM, India)
DATE & TIME: 18 November 2024 to 29 November 2024
VENUE: Ramanujan Lecture Hall (Week 1) & Madhava Lecture Hall (Week 2)
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:
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.
Physics of convective organization: Basics of convection, radiation, Convective aggregation, Idealised modeling, Observations of convective organization, Using simulations to understand physics of convection.
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
