WEATHER forecasts may become less accurate due to the coronavirus pandemic, according to scientists.
That's because forecasters rely on delicate instruments strapped onto commercial aircraft – scores of which have been grounded by the global outbreak.

The stark warning was issued last week by US meteorologist Ryan Finn.
In a blog post on Spectrum News, he explained how planes are vital to the creation of long-range weather predictions.
"Along with radiosondes attached to weather balloons, [atmospheric] data is collected from buoys, satellites, and aircraft," Ryan said. "This includes commercial aircraft."
"Outside of satellite data, aircraft data is the most important source of data in terms of increasing forecast accuracy."
Before the coronavirus outbreak, which has forced a third of the world's population into lockdown and cancelled most commercial flights, more than 1million weather data reports were being sent to these agencies on a daily basis.
According to Stanley Benjamin of NOAA's Earth System Research Laboratory, that number has now dropped by more than 50 per cent.
It's likely that this will have a significant effects on our weather forecasts, Ryan said.
"I'm not trying to make an excuse for any future forecast busts, but less air traffic equals less data to incorporate into weather models meteorologists look at," Ryan wrot.
"This could, in turn, make for a decline in forecast accuracy in the coming weeks and/or months."
According to the NOAA scientist Stanley, a similar effect occurred in 2010.
