Jonny Day

Jonny Day is an academic researcher at the University of Bristol, specializing in Arctic climate dynamics, climate modeling, and cryosphere studies. His work focuses on Arctic cyclones, sea ice predictability, and climate change impacts. He holds a PhD from the University of Bristol (2011) and has contributed to projects like the APPOSITE dataset. Key collaborations include work with the Polar Prediction Project and institutions globally. His research spans seasonal forecasting, climate model development, and historical climate reconstructions.

Research interests include Arctic sea ice variability, cyclone intensification mechanisms, and the interplay between temperature gradients and atmospheric dynamics. Major contributions include studies on Arctic shipping risks and the impact of a seasonally ice-free Arctic on Greenland ice sheets. He has authored/co-authored over 25 peer-reviewed articles and contributed to international climate initiatives.

Day has explored multi-decadal climate variability, model predictability, and the role of Northern Hemisphere snow in Arctic systems. His work bridges climate science with practical applications, such as improving seasonal Arctic navigation forecasts. Collaborations span disciplines from atmospheric science to oceanography, reflecting his interdisciplinary approach to polar research.
