Over which part of the globe did the prevailing winds blow east to west?

The prevailing winds that blow east to west are known as the trade winds. These winds blow from the subtropical high-pressure regions towards the equator across the tropical regions of the globe. The trade winds are found predominantly in the tropics, between 30 degrees north and south of the equator. This means that they blow over regions such as the Caribbean, Central America, Africa, and Southeast Asia.
