GPUs open the potential to forecast urban weather for drones and air taxis

Winds blowing through downtown Dallas

Scientists at NCAR have demonstrated that a new kind of model built entirely to run on graphical processing units, or GPUs, has the potential to produce useful, street-level forecasts of atmospheric flow in urban areas using far fewer computing resources and on a timeline that makes real-time weather forecasting for drones and other urban aircraft plausible.
