Cross-valley wind

From Glossary of Meteorology

cross-valley wind

A wind that blows across the longitudinal axis of a valley from one sidewall to another.

This term is usually applied to a thermally driven (anabatic or katabatic) wind arising when unequal insolation on the two sidewalls causes a strong cross-valley temperature difference. Air then flows toward the more strongly heated sidewall.
See mountain–valley wind systems.
