Answer:
It is true that subtropical deserts are centered around 20 degrees to 30 degrees north and south latitude.
Step-by-step explanation:
The atmospheric environment of subtropical climate inhibits precipitation as the air always descends with clear skies, elevated inversions. Most of the Earth's tropical desert climate occurs between 15 to 30 degrees north and South latitude.
Temperatures are usually high (21-32) and on a daily basis variations are extreme. The deserts are subject to frequent fog and low-level clouds. The cooling results from the oceans and coastal waters give rise to cold currents. The maritime air penetrates less frequently as the high and low sun-monsoonal winds blow along the coast.
