What caused the roaring 40s?
The Roaring Forties take shape as warm air near the equator rises and moves toward the poles. Here, as the temperature gradient decreases, air is deflected toward the poles by the Earth’s rotation, causing strong westerly and prevailing winds at approximately 40 degrees. These winds are the Roaring Forties.
