Why is there little to no rain at the STHPB?

• Air cools as it moves further from the equator to higher latitudes

• Cold air is dense hence cold air subsides at the STHPB/Horse Latitude, resulting in high pressure and suppressing vertical movement for air and a
  lack of mechanism for uplift

• Thus STHPB experiences minimal evaporation for cloud formation and precipitation.
