Well I worked for over 25 years in ATC at the airport that probably gets the most snow in the UK,and our snow team was excellent.As minimal disruption as possible,and if we had more machines even less closures.
Oslo's team for clearing the ramp is more than we had for the whole airport,so if you have enough machines you can operate normally.
It just the end of the world stuff you hear from the south.It's called Winter,so deal with it,and stop saying ''We're not used to it''.Get some proper clothes and start shovelling.
Ps I'll go back to watching Ice Pilots.Funny how their runways always seem to be clear.
