Sick & tired of the heat & humidity & you need a cool, refreshing break? How about a free article on the polar vortex & how it's fickle nature is bringing surprising winter temperature trends to the US, including warming to some parts & cooling to others: www.science.org/doi/10.1126/...
Cold-air outbreaks in the continental US: Connections with stratospheric variations
Extreme US cold linked to two variations of a stretched stratospheric polar vortex can explain a Northwest US cooling trend.

In 2018 I took part in the excellent BBC&STV #Scotland Expert Voices #mediatraining day. The next day I was on the telly talking about the life and scientific legacy of Stephen Hawking who had passed away overnight. The call is open for this year's programme - if you're in 🏴 you should apply! 👇

Excited about our new review paper (Ye et al., 2025) on the relationship between snow/ice variability & weather extremes. I will highlight our analysis that shows a strong relationship between fall Siberian #snow cover & cold extremes in eastern North America:
