What distinguishes Tertiary Winds from primary and secondary winds?

Tertiary Winds are small‑scale, short‑lived, and driven by local geographic factors such as topography and temperature differences, whereas primary winds are global circulation patterns and secondary winds are seasonal monsoonal systems.

Which local wind is known as the "snow eater" and where does it occur?

The Chinook wind, occurring on the leeward side of the Rocky Mountains, is called the "snow eater" because it rapidly raises temperatures and melts snowpacks.
