Key Takeaways:

  • Reduced airline operations globally have significantly impacted the World Meteorological Organization's Global Observing System for weather reporting.
  • In-flight measurements of ambient temperature and wind speed/direction, crucial data points for weather prediction and climate monitoring, have notably decreased due to fewer commercial flights.
  • This reduction in vital high-altitude data can lead to less accurate numerical weather predictions, potentially causing issues like over-warning or failing to predict major weather events.

The drop in airline operations across the US and around the world has had an impact on weather reporting, particular with the input flight crews make to the World Meteorological Organization’s Global Observing System, part of the World Weather Watch program. The WMO provides part of the architecture through which 193 member countries can build weather forecasts as well as monitor atmospheric and climate conditions.
