Explore NASA's NURTURE mission unfolding in Labrador, where scientists fly into the Arctic to study small tropospheric polar vortices (TPVs) and their impact on winter weather. Learn how dropsondes, a modified Gulfstream III, and real-time data assimilation are helping meteorologists reduce forecast uncertainty and improve winter storm predictions for North America and Europe. A beginner-friendly look at why upstream weather matters and how this research translates to everyday forecasts.
