Climate if West and East patterns flipped?

Something like Seattle or Portland I would guess. Maybe a bit colder winters.

climate scientists have done computer simulations of this:

I'm rather surprised; I thought the east coast of the US would warm, west coast would cool.

for US East Coast:

Perhaps the gulf stream shutdown cancels out the warming from ending most of the cold continental flow. Seasonal temperature range and precipitation would be very different of course.

for US West Coast:

The cold Pacific waters currently keeping the west coast cool but the average temperatures are fairly warm for its latitude. But the colder continental flow [flow over Cascades & Sierra would create a warm foehn effect blocking the coldest air so won't be that cold] must not matter much since the Pacific is currently so cold, so oceanic flow doesn't warm much when the wind direction switches [does it exactly switch?]. Upwelling of cold water should stop if the earth's rotation switch, so coastal waters would get much warmer outside of winter.

East Asia warms a lot; unsurprisingly, it has the coldest winters for its latitude in the world currently so it has the most potential to warm, but does it still have monsoonal flow from the Pacific? Its mainly driven by a Thermal Low on the continent, which should be there regardless of circulation, but the wind direction would still be altered. I'd need to think about this more. The continent highs & low vs ocean would still be somewhat similar to today because continents warm & cool faster but the wind flow around pressure systems would be reverse of today. Would this mean northeasterlies from a Bermuda High?

Gulf stream shutdown + prevailing easterlies from the Eurasian continent rather than Atlantic drastically cools northwest Europe of course. Another interesting find, though of course it's just a model:

North African rainfall went up, and the Mediterranean received so much river input it became almost fresh. The reorganisation of the world’s hydrological cycle that we initiated might have frozen Europe

Norwegian mountains would probably get an ice cap; dunno how big it would be
