Why is the Patagonian Desert dry?

In southern South America the zonal air flow is from west to east. Moisture picked up from the Pacific Ocean moves eastward and the Andes Mountains force it upwards where the moisture condenses and falls as rain on the western side of the mountains. The air passing into the eastern, or leeward, side of the mountains is dry and has little to no moisture to drop there. The Patagonian Desert is located in this dry area as well as the Monte Desert
