How would a mountain range in the Persian Gulf impact the climate?

So in the map of my current world building project, the Indian plate never collided with Asia and it, Australia, Antarctica, and Madagascar stayed together as a singular continent. It sits roughly where Australia is, but spans from the tropics all the way down to the polar circle.

However, the Arabian plate collided with Iran, creating a massive mountain range along where the Persian gulf is and raising the Iranian plateau. Also, the Nubian African plate has broken off and moved Westward, making the Mediterranean much larger. I've been trying to figure out how this would impact weather and climate patterns in the region and the globe, but I'd like some more opinions.
