Most of the territory of the United States is situated in the zone of the westerly prevailing surface winds. These winds are found in the latitudes between 30 and 60 degrees, both north and south of the Equator. In the northern hemisphere they are associated with the temperate climate region.

ANSWER:

Most of the US is located in the 'Westerlies zone' of prevailing winds.

EXPLANATION:

The prevailing winds or trade winds are the winds on the 'surface of the earth' that blow from a particular direction. Westerlies are the trade winds that blow from the 'west direction'. These winds are more dominant in the mid-latitudes and blow from 'west to east'. The westerlies also lead to the 'development of strong ocean currents' in the northern as well as southern hemisphere.
