briefly write about the Aridity of Subtropics Causes, locations, etc. Solution The Aridity of Subtropics: the differential air temperature at some specific latitudes makes warmer weather than & some cold air currents may also trigger aridity & advection fog whereas some warm air currents may trigger more air temperature The main cause of aridity is due to the formation of desert weather through \"water deficiency\" & dry climate. These causes are going to form sub-topical desert (BWh) and steppe (BSh) as semi-arid locations in both tropical & temperate regions. The other causes are elevated temperatures with cloudless sky and locations are Chile\'s Atacama Desert or Middle-Latitude Desert. Ocean conveyor, El Nino Southern Oscillation (ENSO): This effcet further increases the oceanic atmospheric pressure in Pacific and finally warmer winds associated with much warmer water leading global climate change..
