With reference to the sub-tropical high pressure belt, consider the following statements:
1. It is affected by Earth's rotation and descent of winds from higher altitudes.
2. It is dynamically induced and characterized with anti-cyclonic conditions.
Which of the statement(s) given above is/are correct?

Solution (By Examveda Team)

Sub-tropical high pressure belt is dynamically induced and characterized with anti-cyclonic conditions. This is why this zone is characterized by anticyclonic con­ditions which cause atmospheric stability and aridity. The conver­gence of winds at higher altitude above this zone results in the subsidence of air from higher altitudes. Thus, descent of winds results in the contraction of their volume and ultimately causes high pressure. This is one of the reasons for the presence of hot deserts of the world in the western parts of the continents in a zone extending between 25°-35° in both the hemi­spheres. This zone of high pressure is called ‘horse latitude’ because of prevalence of frequent calms.
