The stratosphere is a fascinating place; a lid on the turbulent lower atmosphere, a realm of alien dynamics that defy our everyday experiences, and home to the most violent events in the entire atmosphere. Every now and again the stratosphere reaches down and completely changes the weather we experience on the surface. When the stratosphere comes into town, extreme weather changes lives for many of us. It may well play a key role in the single most dangerous experiment humanity ever attempts. So, in short, you really should understand a bit more about what’s going on up there.
In this talk I will give an introduction to the key features, dynamics, and impacts of the stratosphere. In particular I’ll be discussing sudden stratospheric warmings and their impacts on surface weather, the subject of my PhD, and also the potential use of the stratosphere in geoengineering
