From Glossary of Meteorology

Atmospheric ducting

An anomalous mode of electromagnetic wave propagation where waves are bent back toward Earth’s surface due to significant decreases in atmospheric refractivity, generally found in the lower atmosphere or atmospheric boundary layer environment.
See radio duct.
