Interesting. Is there other research on this? How well tested is the mode?

It is something i have wondered about because proximity to the heat in the sea is clearly an important factor too, so i am interested. Surely the Gulf Stream must have some impact?

The article doesn’t say that the ocean is irrelevant just that it’s not the oceanic currents that dominate. The main thing is just having an ocean at all coupled with prevailing winds being west to east. Hence Seattle, which is mild but does not benefit from Gulf Stream like currents

Yes, I get that. To clarify I meant proximity to heat in the sea "stored" from warmer times of the year without the effect of the Gulf Stream is clearly an important factor.
