In the southern hemisphere there is very little land between 40 and 60 degrees south latitude, so the westerlies blow with great strength. Between 40 and 50 degrees they are called the Roaring Forties, and between 50 and 60 degrees the Furious Fifties or Shrieking Sixties. Trade winds blow from the subtropical highs toward the equator, and the doldrums are a calm region near the equator.
