Basics of Geophysical Fluid Dynamics by Jim Thomas
DISCUSSION MEETING: PEDAGOGICAL PROGRAM
MATHEMATICAL MODELING OF CLIMATE, OCEAN, AND ATMOSPHERE PROCESSES
ORGANIZERS: Jim Thomas (ICTS-TIFR, India), Ashwin K Seshadri (IISc, India) and Aman Gupta (Stanford University, USA)
DATE & TIME: 26 June 2023 to 30 June 2023
VENUE: Madhava Lecture Hall, ICTS Bengaluru
This pedagogical program is aimed at students across the country, with special emphasis on Masters students and final year undergraduate degree students. Lecturers at this program will discuss fluid dynamics of the atmosphere and the ocean and its impact on climate scale processes. No prior background in climate-atmosphere-ocean dynamics is expected of participants. Topics that will be discussed include turbulent dynamics and convection in the ocean, monsoon dynamics, dynamical sys...

Fluids in Motion: Crash Course Physics #15
Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawnmowers.
In this episode of Crash Course Physics, Shini talks to us about how fluids in motion are really, really, REALLY powerful things.

The ultimate fluid mechanics tier list
Fluids can do really cool things, but which things are the coolest? Soon-to-be-Dr Kat from the University of Bath, studying for a PhD in fluid mechanics, put fluid effects including laminar flow, vortex streets, and the Kaye effect.
What's this based on? Almost entirely just vibes.

Geophysical Fluid Dynamics- Geometry & Ecology
Techniques uncovering transport barriers and structures in environmental flows are poised to make a considerable impact on the field of ecology. Here we discuss some results relevant for real-time analysis and prediction of geophysical transport structures, which have arisen from applications to fluid-borne microbial ecology. Focusing on aeroecology, we consider challenges involved in forecasting atmospheric Lagrangian coherent structures, including the effect of subgrid turbulence and ensemble averaging. We also consider notions that may be relevant in an ecological context, such as persistent barriers, which may lead to the most diverse populations (in terms of origins) sampled sequentially at a geographically fixed location.

Spectral methods for geophysical fluid dynamics
I will survey recent transfer operator theory and methods for analysing geophysical fluid flows. These include a selection from: tracking coherent features from the meso-scale to the
global scale using models and observations, computing optimal stochastic and deterministic perturbations to enhance fluid mixing, rigorous computation of statistical limit laws, and theory for quenched random limit laws.

Techniques uncovering transport barriers and structures in environmental flows are poised to make a considerable impact on the field of ecology. Here we discuss some results relevant for real-time analysis and prediction of geophysical transport structures, which have arisen from applications to fluid-borne microbial ecology. Focusing on aeroecology, we consider challenges involved in forecasting atmospheric Lagrangian coherent structures, including the effect of subgrid turbulence and ensemble averaging. We also consider notions that may be relevant in an ecological context, such as persistent barriers, which may lead to the most diverse populations (in terms of origins) sampled sequentially at a geographically fixed location.
