Abstract

Quasi‐periodic oscillations of period 10–15min, observed in net flux of long‐wave radiation, surface temperature and wind during the development of a radiation fog on 7 December 1971, were found to have a significant phase relationship which persisted for about three hours. An interpretation of this phenomenon is suggested in terms of the evidence given by Roach, Brown, Caughey, Garland and Readings (1976) and Brown and Roach (1976) that the development of radiation fog is controlled by a (fluctuating) balance between radiative cooling and turbulent diffusion.

## Abstract Quasi‐periodic oscillations with a period of about 40 min are observed in visibility, temperature, water vapour, wind speed and long‐wave radiation during the fully developed stage of a shallow radiation fog. These oscillations were observed up to a height of about 60 m, whereas the fog
