I'm not familiar enough with the correct terms I need to use, so forgive me if I ask this poorly. I'm building a fantasy world in which my MC is a healer, and I thought it would be fun to put her in a rainforest, since a lot of cool healing herbs can be found there. So I'm basing the rainforest loosely on what's in the Amazon, and the country she is in is based roughly on Peru in the sense that there are both mountains and a rainforest, only I've flipped it mirror image with the ocean and the mountains on the east and the rainforest to the west.
However, after studying prevailing winds and the Coriolus effect, I realized I have a problem. At latitudes between 0 and 30 degrees, where a rainforest needs to be, prevailing winds are easterlies - that is, they blow from the east. On our Earth, that means the prevailing winds bring a lot of rain into the Amazon. But with my world's mountain range being on the East, they're going to block the prevailing winds, and I'll have no rainforest.
So I'm wondering, if a habitable planet were tipped 23.5 degrees in the opposite direction of how our Earth is tilted, would that make the prevailing winds between 0 and 30 degrees latitude blow from the west? If not, what effect would a reverse axis tilt have?
