  • Trade winds received there name when traders sailed through those parts so the could trade
  • the Horse Latitudes are areas of calm winds or no wind at all
  • the Horse Latitudes got their name from ships caught in these calm wind areas had to throw horses over board
  • prevailing westerlies blow from the Horse Latitudes to the North and South poles
