2025 Halley Public Lecture: Cloud mesoscale organisation and climate

Cloud mesoscale organisation and climate: new insights from models and observations
Sandrine Bony (LMD, CNRS, Sorbonne University, Paris)
 

Abstract: Clouds display striking forms of organization on the mesoscale (a scale ranging typically from 2 to 200 km). Far from being a mere curiosity, this organization challenges our understanding of atmospheric physics and climate. What processes control cloud patterns and organizations? How much does the mesoscale organization of convection matter for climate? I will show how new observations from satellites and field campaigns shed light on how and why clouds organize at the mesoscale. Then, based on simulations from a new generation of climate models, I will explore the role that this mesoscale organisation might play in climate and climate change

The talk will be followed by a drinks reception. The event is free and open to all; register now via the link below to attend.
