This is, I am sure, more than coincidence as I have seen this pattern for
many years. Scandinavian countries dominate. Es is not exclusively Scandinavian stations, but these are far more common than earlier in the Es season here. It is almost like there is some other Es mechanism in play.

Hi Roger,
ReplyDeleteEven here in Southern Scandinavia (Denmark) I have noticed a similar trend over the years.
Agreed, our sample is a bit small, so I would also like to hear the observations of more people at our latitudes.
