The coronavirus pandemic has topped over 380,000 cases globally, with nearly 2 billion people worldwide affected by a lock-down, curfew or other movement restrictions.
Now, it could impact weather forecasts too.
Amid the spread of Covid-19, airlines have had to suspend passenger flights and cut schedules. Experts have found this has led to a severe decrease in aircraft-based observations, which help with weather predictions.
Weather data collected by aircraft are crucial in forecast models that control daily weather predictions. Aircraft-based observations also help in greatly reducing errors in weather forecasts.
There has been a 42% reduction between March 1 to 23 in the number of aircraft reports received all over the world, the European Centre for Medium-Range Weather Forecasts (ECMWF) said in a news release on Tuesday.
