Amarok GTI, I would strongly encourage you and your affected colleagues to submit an AMIR for each one of those incidents that affected your operations. You can also make it part of your internal company safety report process related to any incident.
I have had reason to submit one in the past under similar circumstances when conditions went from above alternate minima to below landing minima enroute and I had to make an in-flight diversion, refueling, and wait conditions out before proceeding to the destination. It was internally investigated and a decent completed report summary came back to me a few months later. The incident was going to be used for training forecasting staff in future scenarios where the same conditions and phenomenon could develop again.
