Hot deserts like Sahara, Arabia etc. receive very negligible amount of rainfall. This is because they :

Hot deserts like the Sahara and Arabia are primarily characterized by their location within the Sub-Tropical High-Pressure Belts, also known as the Horse Latitudes [c5]. In these regions, the descending limb of the Hadley Cell creates stable atmospheric conditions where air sinks and warms adiabatically [t1][t6]. This subsidence suppresses convection and cloud formation, making it the least favorable condition for precipitation [c5]. Additionally, these deserts are often situated on the western margins of continents where trade winds are off-shore, meaning they blow from land to sea and carry little moisture [c1][c4]. While the lack of moisture-bearing winds and cold ocean currents contribute to aridity [c3][c4], the fundamental meteorological cause for the negligible rainfall in these specific tropical latitudes is the persistent high-pressure system that prevents the ascent of air necessary for condensation [c3][t4].
