The number of aircrafts operating has considerably reduced as a result of the coronavirus pandemic, and this is affecting the input gotten by the sophisticated computer programmes needed to make large-scale weather forecasts.
The quality of the output of these programmes depend on the quality of the input it receives, and the input from aircrafts, which feeds back real-time wind data, is second only to satellite inputs in weather forecasts.

As a result of the outbreak of coronavirus, there have been a significant decrease in the number of aircrafts flying, and therefore, in Europe, there have been about 65% decrease in the report usually received from aircrafts, while globally, we have seen about a 42% reduction. These factors will therefore affect the accuracy of weather predictions.
