The Sahara and Australian deserts among others are associated with the subtropical high?

Yes, the Sahara and Australian deserts are among the many regions worldwide influenced by the subtropical high-pressure zones found between 20 to 30 degrees latitude in both the Northern and Southern Hemispheres. The Sahara, located in Northern Africa, experiences the influence of the subtropical high of the Northern Hemisphere, characterized by clear skies, stable atmospheric conditions, and descending air masses, contributing to the extremely dry and arid desert conditions. Similarly, the Australian desert also encounters the influence of the subtropical high in the Southern Hemisphere, exhibiting hot and dry climatic conditions.
