What does a name of a wind tell us?

A name of a wind can tell us a lot about the characteristics of the wind. For example a sea breeze is typically a local wind that blows from the sea to the land while a land breeze is the opposite.

The following list provides a more detailed explanation of what a name of a wind can tell us: Local or regional origin (e.g. sea breeze land breeze) Strength (e.g. gale breeze) Direction (e.g. northwesterly) Season (e.g. summer sea breeze monsoon wind) Time of day (e.g. morning breeze sunset breeze)In addition some wind names are based on mythological or folkloric sources such as the witch wind or devil wind.
