Morphology

prevailing + westerly

The meaning 'a wind that blows predominantly from the west' is directly derivable from combining 'prevailing' (most widespread) with 'westerly' (coming from the west). This straightforward adjectival composition is common in weather vocabulary and across languages, so a B1 learner who knows the constituents should be able to understand the MWE.

Etymology

Prevailing westerly comes from sailors and weather watchers who noticed a wind that usually blew from the west. The word westerly means a wind 'from the west' and prevailing means 'most common', so the phrase names the wind that most often blows from the west and shapes the local weather.
