How warm Mediterranean sea will be if we cut off inflow from Atlantic a replace them with inflow from tropical Indian ocean? Red sea is now massive strait. A lot deeper and larger than Gibraltar in real world. Red sea in summer has SST around 32C/90F degrees and remain above 20C even in the winter. And this water will now fed mediterranean. Instead of relatively cool Atlantic waters which barely have SST 20+ C/70+ F in late summer. And what about other impacts? Formation of warm core cyclones, precipitation, etc.

Discuss now.
The warmer SSTs in the Mediterranean would likely cause more convection and thunderstorms in summer. The Mediterranean might even have more tropical cyclones.
Presumably ocean water would still flow in at the surface and would be concentrated by evaporation, become more saline, sink and flow out underneath the surface inflow.
It would be more interesting I think if the Mediterranean was open at both ends. Probably this would cause the whole world to warm somewhat as it would re-establish more circulation between the warmer parts of the oceans that was cut off when the exchange between the Pacific and Atlantic was severed by the formation of the isthmus of Panama.
The climate wouldn't be much different as nothing is there to diminish the influence of the Sahara Desert which dominates the Mediterranean during the summer. So it would still be a Med climate. I imagine that winter would be quite warmer though and probably more stormy. I think that the warmer water with cold storms coming over it in the winter would mean that instead of having a maximum precipitation in October, it would occur in December/January like it does in CA.
The Baltics would no longer have a cold winter and Greece would be much warmer in the winter, as would Turkey. It's possible places like Greece/Turkey would be as hot as Iraq.
The fish stock would change from Atlantic based types of fish to Red Sea type of fish. This would mean the cuisine would change greatly.
So you would have countries like Italy eating cornetfish instead of European Seabass. I would presume that the Middle Eastern way (or Southern US way) of preparing fish would prevail from Spain to Egypt instead of the European way. Cod would virtually be eliminated, Italy would not eat it at all. France and Spain could still eat it because of their Atlantic coastline.
It would be great because Red Sea catfish would live all over the Mediterranean. You'd be able to get really great fried catfish, it would be like the American South.
Another effect of this would be that Egypt would have many more cities along the Red Sea and I believe the climate of Cairo would be fully Mediterranean not Desert. Egypt would basically be many times its current population.
I also estimate that they would've been a SpanMoro Canal in between Spain and Morocco so the effects would be mitigated slightly, just like how the Suez Canal brings some Red Sea water into the Eastern Mediterranean.

I expect something similar. Evaporation across semi-enclosed Medi. will naturally create pressure gradient which will help draw waters from south to the north. And dense salty waters from Medi. will flow beneath to the Indien ocean. Same like in the Gibraltar strait. And Indian ocean already exchange its waters with Atlantic around southern tip of Africa

I think Cairo will be still desertic because of winds. Low presssure areas will be still coming from the west and prefrontal winds will blow from Sahara and all moisture will be pushed towards Turkey. Btw. Interesting note on the food.
And why Baltics will be winter free? They are still far away from Medi. Maybe more moisture from south will support heavier snowstorms in conjunction with continental air from Siberia.

The Arabian Sea and Persian Gulf have 90°F+ water in summer, yet that is the dry season in that region, due to high pressure
Yes. Increase in t-storm frequency in summer will be most prominent in the northern outskirts (Generally north of 40°) where t-storms are relatively common or they are common (north Adriatic, Po valley). But cities like Naples, Firenze, Roma have only borderline Csa/Cfa climate instead of pure Csa and slight increase of t-storm should result in shift to the Cfa climate. For example. Tirana (capital of Albania) has mediterranean rainfall pattern, but rainfall even in the summer is still to heavy to recognise this city as Csa climate
