Westerlies, or prevailing westerlies.

Westerlies are prevailing winds from west to east that are found in the middle latitudes between 30 and 60 degrees latitude. These winds are stronger in the winter hemisphere and times when the pressure is lower over the poles, while they are weaker in the summer hemisphere and when pressures are higher over the poles.

The westerlies are important in carrying the warm, equatorial waters and winds to the western coasts of continents.
