Citizen science data reveals winter warming delays cherry bloom in the Pacific Northwest, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is altering ecological systems, including the phenology of flowering plants. Shifts in the bloom date of cherry trees are a global concern considering their cultural, agricultural, and horticultural importance. Ornamental cherry is a prominent component of the University of Washington campus (Seattle, USA), providing an opportunity to ...

Convergence of forecast distributions on the synoptic scale

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether convergence of sampling uncertainty with ensemble size, as seen in convective‐scale models, is also seen in global ensembles where synoptic‐scale weather systems play a greater role. The nature of convergence was indeed similar, as shown in this figure where the 50‐member ensemble from a single grid point was large enough for the

Resilient Timed Elastic Band Planner for Collision‐Free Navigation in Unknown Environments

Journal of Field Robotics, EarlyView.
ABSTRACT In autonomous navigation, trajectory replanning, refinement, and control command generation are essential for effective motion planning. This paper presents a resilient approach to trajectory replanning addressing scenarios where the initial planner's solution becomes infeasible.
