How weather apps are trying to be more accurate

Travelling the world by bicycle for two years might be too physically challenging for most of us, but Zoe Ashbridge has found a way to make the pedalling a little bit easier.
She and her partner and travelling companion Stewart use an app called Windy to track the direction of the wind.
"We use it daily," says Zoe, a 33-year-old from Shropshire. "It saves us wasting time and energy.
"Our bikes weigh around 30 to 40kg, and if we're going against the wind, we can get sore knees. It prevents all that. Why spend two hours cycling when the next day it would take 30 minutes":[]}
