I admit to being an enthusiastic novice but I am puzzled by the range of emotions on here. Some clearly have an agenda and skew the model output to fit...clearly unhelpful. In my simplistic view until much nearer the time of trop response, say at least 10 days, then the actual pressure set up will not be known within probably a few hundred miles or more so obviously as the models react to data their output will vary considerably. This was observed I believe in the few weeks preceding the March 2018 BFTE. So I really cannot see the point of writing off the effects of the SSW for the UK based on data models that will. Inevitably change.
When the trop block between the vortices occurs it’s effect on the NH will be felt and influence our little island considerable, it could well be that our resident hp system at the time will be forced to migrate...so why all the pessimistic views based on current output?
just my pennies worth, with my limited understanding of the science involved. The experts on here are not throwing in the towel and that’s good enough for me.
