Detailed explanation-1: -30° N and 30° S. Only at these latitudes in the north and the south can these dry areas be found.
Detailed explanation-2: -The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for winds to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds).
Detailed explanation-3: -As air above the equator rises, it cools and is unable to hold all of the moisture–so it rains at the equator, creating the climate and moisture conducive for tropical rainforests (known as the intertropical convergence). The air that rises at the solar equator descends near 30 degrees N or S.
Detailed explanation-4: -Due to the rotation of the earth, there is a build up of air at about 30° north latitude. (The same phenomenon occurs in the Southern Hemisphere). Some of the air sinks, causing a belt of high-pressure at this latitude. The sinking air reaches the surface and flows north and south.
Detailed explanation-5: -At 30 degrees latitude, the dry air creates deserts. Major deserts of the world, including the Sahara, Arabian, Gobi, Great Victoria, Kalahari, Atacama, and the Chihuahuan/Sonoran deserts occur around 30° N or 30° S.
