Subtropical deserts are centered around 20-30 degrees north and south latitude, true or false?

It is true that subtropical deserts are centered around 20 degrees to 30 degrees north and south latitude.

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.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
