Fog is the second most common cause of weather-related aviation accidents behind strong winds. The impact of fog on the operations of the national airspace system can cost as much as $200,000 for just one single airport. Air traffic safety and efficiency would be improved if fog events were more accurately forecast by weather service providers. This improvement would give aviation operations and transportation departments enough lead time for alerts and avoidance measures to be put in place.

NCAR scientists recruiting the public to help ground-truth hurricane risk app

Output from a wind forecast

A team of researchers is test-piloting the first phase of a web application that will ultimately allow users to get tailored information about the likely storm impacts at their specific locations, including information on the likelihood of high winds, when those winds will arrive, and how much damage they may cause to their homes.

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.
