Explore the fascinating journey of a raindrop in this 1-hour 15-minute lecture by Rama Govindarajan from the International Centre for Theoretical Sciences. Delve into the fluid dynamics of cloud formation, examining how raindrops and turbulence interact within clouds. Learn about the formation and growth of raindrops, their impact on surrounding turbulence, and why understanding this process is crucial. Cover topics such as the Indian monsoon, the water cycle, cloud droplet formation, and the challenges of droplet growth. Investigate the role of turbulence in cloud dynamics, including its mixing effects and potential for non-uniform distribution. Gain insights into ongoing research in related areas, such as flexible filaments on fluid interfaces and collisions in viscous fluids. Conclude with a Q&A session to further explore this intriguing subject.

The life history of a raindrop
Work of S. Ravichandran "Dr."
The Indian monsoon
The Water Cycle
Can the puff rise through several kilometers?
Is the wetness "enough"?
Then, condensation only if
Summary
That was easy - now comes the hard part: Cloud drop to rain drop
Droplets growing too fast - The bottleneck question
Why don't they fall?
Droplets growing too fast
Turbulence: ubiquitous at large scales, made up of vortices
Turbulence mixes
Does turbulence "uniformise" everything?
But ....... simulations of Samriddhi Sankara Ray
Evolution with phase change
First become Turbulence in a cloud
Flexible filaments on fluid interfaces: Ganga Prasath
Collision in viscous fluid: Summit Birwa - Shallow water theory predicts
