I know the pilots are required to report turbulence experienced in the aircraft via PIREPs. The data for turbulence with lat,long,alt and the severity is available. I am wondering if the PIREPs are somehow used to modify operations? Or do pilots of other aircraft that will fly through the same region in the future just look out for it without any rerouting?
Also, are there any heuristics on how long the turbulence reported is likely to linger?
