Greetings, Original ger designs have a roof hole, at the peak, with a flap of material that is the same as the rest of the wall/roof material, for covering and exposing purposes. This, combined with the ability to have air coming in, at the base of the walls, provides a lovely cool convection flow of air, cooling the space. Normally this is achieved by lifting the cloth walls, and flipping aside the roof hole cover, but I've seen it work in a hexayurt with a series of low to the ground vent holes (with plug, for the nighttime) sealed with furnace filters, and a close to peak vent, designed the same way.
It's amazing how much that helps, and combine that with a swamp cooler, and you have quite a lovely space. Of course, if you find yourself an artist/engineer with an interest in history, there are stone window covers, which take advantage of the cooling effect of forcing the air through narrower apatures, thereby speeding and cooling the air. Carving something like that, or casting it, or even 3-D printing it ... might make one quite popular.

We put a candy cane of bendable duct through the roof and wrapped the open end in some scrap filter. Inside the yurt, the vent had a small flip door. We'd flip that vent open up during the day to get the hot air out and close it at night to keep the warm air in. No swamp cooler; nothing tricky. Granted, last year was mild but this totally did the trick for us.
