We use data collected on 9 January 2015 to evaluate relationships between ice fog and turbulence variables. A very shallow (about 10 m) ice fog was observed due to radiative cooling along with the mountain circulation from 0710 MST to 0915 MST. This ice fog event occurred when air temperature were of -9 °C, which is relatively warm for the ice fog to occur. Relative humidity with respect to ice was ≈105% before and during the fog episode. The results show a constant longwave radiative cooling of -45 Wm-2 throughout the night. Observed particle concentrations indicate that that bigger particles (0.1 10.0 μm) were formed through the transformation of smaller particles (0.3 1.0 μm). An extremely low wind speed (mostly < 0.5 m s-1) was measured as well during the observational period. Quasi-periodic oscillations were observed before and during the fog event with a time period of about 30 minutes. These oscillations were detected in liquid water content, temperature, wind direction, relative humidity, and turbulent kinetic energy. A significant phase correlation between wind direction and visibility was found where a rapid decrease in visibility always following a rapid change of wind direction.
