Located in the subtropical latitudes, these deserts are caused by permanent subtropical anticyclones that bring warm and dry air masses. The summers are extremely hot, winter is much better for hiking. Another characteristic of these deserts is the large difference in temperature between the day and night.
The most well-known subtropical desert is the Sahara in the Northern hemisphere, which joins the Arabian and Iranian desert and the beautiful Thar desert in India. In the Southern hemisphere, we can cite the Kalahari desert in Africa and the Simpson desert in Australia.
