Final answer:
The wind band located between the horse latitudes and the doldrums in the Southern Hemisphere is called the trade winds, characterized by consistent east-west direction and speed.
Step-by-step explanation:
The wind band located in the Southern Hemisphere between the horse latitudes and the doldrums is called the trade winds.
These are the prevailing east-west wind patterns that are found in the Earth's equatorial region. The trade winds in the Southern Hemisphere blow from the southeast to the northwest and are known for their consistency in direction and speed.
Similar patterns of east-west wind movement can be observed in the atmospheres of the giant planets, such as Jupiter and Saturn, with their jet streams and alternating wind streams.
