Seasonal and regional jet stream changes, their drivers, and how to connect them.

The mid-latitude jet streams play a defining role in shaping regional weather and climate, making it crucial to understand their current state as well as future changes under anthropogenic forcing. While model uncertainties have reduced over time, significant spread in projections still exists. The problem is exacerbated by a multitude of different jet stream drivers whose influence varies with season and region. This talk will discuss some work in trying to constrain future jet projections and give an overview of regional and seasonal characteristics of jet streams and their drivers. It will further discuss potential new avenues for establishing meaningful physical relationships within the high-dimensional frameworks of jet streams and drivers to better understand regional impacts.
