But Chen says it could be a big problem for many industries-like utilities, which have to estimate household heating and cooling needs in order to meet electricity demand. After all, weather is notoriously unpredictable. Subpar forecasts may sound like little more than a headache. The results are in the journal Geophysical Research Letters. Europe made out better, thanks to its dense network of ground-based weather stations. and China, were also affected because fewer flights means less data. In Greenland, for example, the accuracy of temperature forecasts has decreased by as much as 3.5 degrees Fahrenheit.Īreas with heavy air traffic, like the U.S. And I see temperature, wind speed-forecast accuracy all goes down.”įorecast quality declined the most for long-range projections and over remote areas where planes are one of the few sources of data. “I analyzed three months of spring, which is March, April and May. But with the coronavirus grounding flights around the world, meteorologists are feeling the loss. And planes are one of the best ways to get such info, since they sample the atmosphere at different altitudes and locations. To create weather forecasts, meteorologists need to feed accurate information about current weather conditions into their models. Ying Chen, a meteorologist at the University of Lancaster in England. So you can imagine the gap of observations.” So currently, possibly, we just have one quarter of aircraft running. “In February, let’s say, we have 100 percent. During the pandemic, however, air travel has come almost to a halt. ![]() As jetliners carry passengers around the world, they also collect vital weather measurements, like air temperature and wind speed. But there is a link: commercial air travel. Here are two things that you probably didn’t think were connected: the COVID-19 pandemic and weather forecasts.
