I am a Postdoctoral Research Scientist at Columbia University in New York, working with Lorenzo Polvani. I study large-scale climate dynamics and variability, stratosphere-troposphere coupling, subseasonal-to-seasonal predictability and its applications. I am also Co-Editor-in-Chief of the RMetS Weather journal.
In October 2021, I completed a PhD in the Department of Meteorology at the University of Reading, UK. My PhD, “Stratosphere-Troposphere Coupling on Subseasonal Timescales”, was supervised by Andrew Charlton-Perez and Steve Woolnough at the University of Reading, and Jason Furtado at the University of Oklahoma. The project developed an understanding of the influence of the Scandinavia-Greenland pattern on the stratospheric polar vortex and its representation within current S2S forecast models, and characterised the influence of the stratospheric state on North American weather regimes. The results of the work can be found in three published papers (https://doi.org/10.1029/2019JD030940, https://doi.org/10.1002/qj.3892, https://doi.org/10.1029/2019GL085592) and a fourth currently under revision.
Prior to my PhD, I gained a first-class Master’s degree in Meteorology and Climate (MMet) from Reading, during which I spent a year at the University of Oklahoma. My MMet dissertation research was supervised by Paul Williams and Tom Frame and spawned a Nature paper on increases in vertical wind shear at aircraft cruising altitudes over the North Atlantic and its consequences for clear-air turbulence.
In July 2018, I went viral on Twitter by comparing the UK heatwaves of 2018 and 1976, which showed how the event in 2018 was less unusual with respect to the global background climate.
I am originally from North Yorkshire, and have a fondness for outdoor activities including running, hiking, and a bit of birdwatching. I also enjoy storm chasing in the US Great Plains, and have seen several tornadoes. My photo of a tornado near Forgan, OK on 17 May 2019 features in the frontispiece of the second edition of Introducing Meteorology: A Guide to Weather by Jon Shonk.
