I suggest you read up on Rossby waves Paul as it is they that determine

whether something is retrogression or not. This case wasn't as the waves are

in a progressive mode. Dynamical meteorology is a specialised subject (which

I taught many years ago) but there is plenty of stuff on the Net about

Rossby waves.

Thank you Will and good to see you posting again. I knew you wouldn't be able to resist in the end.

So between 12th and 16th March, did the surface high retrogress?
