When I compare wind speed (km/h) in the web, android app and Weather Underground (WU), there are mismatches. I understand that the zoom factor applied affects the averaging per time unit displayed for a given device.
However the web data in this - admittedly - small sample never gets beyond 13 km/h for gusts, whereas WU will show gusts up to 36.4 km/h and the android app has several hits above 40 km/h. No zoom factor combinations can provide better agreement between devices.
Can somebody please explain to me why the web data differs so much from the other two devices.
