Mountain events could improve safety with ultra-high resolution weather models

American Geophysical Union

Ultra-high-resolution weather models should be used for forecasts for athletic events held in mountainous terrain, as highlighted by a new study in JGR Atmospheres that uses the 2021 Gansu ultramarathon as a case study. Credit: David Marcu/Unsplash
